This guide dives deep into the discontinued but still widely used Murrelektronik M8 female cordset with part number 7000-08061-2210500. We’ll unpack its electrical ratings, mechanical design, cable construction, installation guidelines, and the most sensible replacement options now that it has reached end of life (EOL). Along the way, you’ll see how understanding the details behind a Murrelektronik M8 female cordset can help you make smarter decisions about uptime, safety, and long‑term maintainability.
Whether you’re maintaining an existing machine, standardising on new cable assemblies, or reviewing legacy components, this article will help you treat the Murrelektronik M8 female cordset not just as a catalogue line, but as a carefully engineered part of a larger system.
Overview of the Murrelektronik M8 female cordset 7000-08061-2210500
At its core, the Murrelektronik M8 female cordset with article number 7000-08061-2210500 is a pre‑moulded single‑ended sensor/actuator cable. On one side, you have a straight (0°) M8 female A‑coded 4‑pole connector that mates with common sensor ports. On the other, you have flying leads: a free cable end that can be terminated into terminal blocks, I/O modules, junction boxes, or custom harnesses. That combination is exactly why this Murrelektronik M8 female cordset has been a workhorse in countless machines.
The cable itself is a 5 m long PUR‑jacketed, grey cable with four conductors of 0.25 mm² each. This construction aligns with the typical needs of low‑power sensor and actuator circuits. When you specify this Murrelektronik M8 female cordset, you’re getting a compact connector interface plus a robust, flexible cable designed for industrial environments rather than office‑grade wiring.
From a logistics point of view, the product carries the manufacturer number 7000-08061-2210500, with additional commercial identifiers such as a GTIN/EAN code and a defined customs tariff. The cordset is manufactured in the Czech Republic and has a mass around 0.165 kg. These small details are often overlooked, but in many projects the exact article number and country of origin for a Murrelektronik M8 female cordset matter for documentation, approvals, and spare‑parts management.
One important status note: in the latest manufacturer documentation, this article is now flagged as EOL / discontinued. That means the Murrelektronik M8 female cordset 7000-08061-2210500 is no longer promoted for new designs, and engineers are encouraged to evaluate recommended alternatives. However, it is still very relevant when you’re supporting existing systems that already use this exact Murrelektronik M8 female cordset, or when you’re trying to choose the most compatible successor.
Electrical ratings of the Murrelektronik M8 female cordset
Before you drop any component into a control system, you need to understand its electrical limits. The Murrelektronik M8 female cordset is rated up to 50 VAC and 60 VDC, with a maximum of 4 A per contact according to the manufacturer datasheet. For many sensor and small actuator applications, actual loads are far lower than these limits, but keeping enough headroom is a key part of good design when using a Murrelektronik M8 female cordset.
Some distributor‑hosted datasheets add an extra nuance: for UL‑listed use, the operating voltage is limited to 30 VAC/DC. This doesn’t mean the Murrelektronik M8 female cordset suddenly behaves differently; it simply reflects how certification bodies draw their safety boundaries. If your machine is being evaluated under North American standards, it’s wise to configure your circuits so that the Murrelektronik M8 female cordset never sees more than 30 VAC or 30 VDC in UL‑critical segments.
The product carries a rated surge voltage of 1.5 kV, falls into material group I under IEC 60664‑1, and is defined for pollution degree 3 environments. Put simply, the Murrelektronik M8 female cordset is designed for typical industrial atmospheres where conductive dust, moisture, or mild contaminants may be present. Keeping the assembly within its specified voltage limits and creepage/clearance assumptions helps ensure the Murrelektronik M8 female cordset delivers long‑term, trouble‑free operation.
It’s also important to distinguish between the ratings of the connector and the properties of the cable itself. The internal copper conductors and insulation in the cable are specified for up to 300 V nominal in the cable table, but the connector assembly as a whole is rated for 50 VAC / 60 VDC. In design reviews, you should always size the circuit based on the lower of these values. That way, the Murrelektronik M8 female cordset is always operating inside a conservative envelope.
Finally, remember that this is a passive component with no LED indication. The Murrelektronik M8 female cordset won’t tell you if a sensor is powered or not; it simply provides a low‑resistance path for current. For diagnostics, you’ll still rely on IO modules, test equipment, or advanced fieldbus devices, even though the humble Murrelektronik M8 female cordset is doing crucial work behind the scenes.
Mechanical and environmental design of the Murrelektronik M8 female cordset
From a mechanical point of view, the Murrelektronik M8 female cordset is engineered for secure, repeatable connections in harsh environments. The connector uses a standard M8 × 1 screw coupling, with a recommended tightening torque of 0.4 N·m and a width‑across‑flats of SW9. That may sound like a small detail, but in practice it means you can use common torque tools and sockets to tighten the Murrelektronik M8 female cordset consistently across an entire line.
Ingress protection is stated as IP65, IP66K, and IP67 when the connector is properly inserted and tightened. In other words, the Murrelektronik M8 female cordset is designed to withstand dust, water jets, and temporary immersion, provided you respect the torque specification and use a compatible mating connector. If connections are left loose, even the best Murrelektronik M8 female cordset cannot guarantee its IP rating, which can lead to moisture ingress, corrosion, or intermittent faults.
Material choices also play a big role in durability. The contact base is made from copper alloy with gold‑plated surfaces, giving the Murrelektronik M8 female cordset excellent contact reliability and corrosion resistance. The sealing gasket uses FKM, a material known for its chemical and temperature stability. The locking hardware is made from zinc die‑casting with a nickel‑plated finish, and the overmould is specified as PUR. Together, these materials help the Murrelektronik M8 female cordset survive vibration, mechanical shocks, and cleaning processes in industrial settings.
On the installation side, the assembly is listed as suitable for use in corrugated tube with an internal diameter around 6.5 mm. This compatibility makes it easier to route the Murrelektronik M8 female cordset through protective conduit in cable chains, machine frames, or panels. When combined with proper strain relief at both ends, the Murrelektronik M8 female cordset can remain mechanically stable even when the connected machine elements are in motion.
Temperature range is another key environmental aspect. The overall operating range for the Murrelektronik M8 female cordset is typically −30 °C to +85 °C, assuming the cable stays within its own defined limits. This covers a wide spectrum of normal factory environments, though extreme cold or hot applications may warrant newer variants or different cable families. Knowing these environmental boundaries helps you avoid using a Murrelektronik M8 female cordset in conditions where the materials could be overstressed.
Inside the cable: how the Murrelektronik M8 female cordset is built
A connector is only as good as the cable behind it, so it’s worth looking closely at how the cable in the Murrelektronik M8 female cordset is constructed. The manufacturer describes the cable with identification number 221 and type 2, featuring a grey PUR outer jacket with an approximate outer diameter of 4.6 mm. That jacket is not just cosmetic; it’s the first line of defence for the Murrelektronik M8 female cordset against abrasion, oil, and mechanical stress.
Inside the jacket, the Murrelektronik M8 female cordset uses four conductors of 0.25 mm² each, which roughly corresponds to AWG 24 in many documentation systems. The conductors are bare, stranded copper built with 32 strands of 0.1 mm wire per core. This fine‑stranded design gives the Murrelektronik M8 female cordset a good balance between flexibility and robustness, making it suitable for installations with moderate motion or cable routing around tight spaces.
Each conductor is insulated with PVC, with carefully controlled dimensions and hardness values. The cores are colour‑coded brown, white, blue, and black, and they are twisted together. Twisting reduces crosstalk and helps stabilise impedance in signal circuits, which is important when the Murrelektronik M8 female cordset is used with fast‑switching sensors or high‑frequency signals. The cable weight is about 32 g per metre, which makes the Murrelektronik M8 female cordset reasonably light while still feeling solid in hand.
Electrically, the cable portion of the Murrelektronik M8 female cordset is rated up to 300 V in nominal cable terms. The line resistance is specified around 79 Ω/km at 20 °C, which is typical for conductors of this size. The insulation withstands 2 kV for 60 seconds in wire‑to‑wire and wire‑to‑jacket tests, underscoring the quality of the insulating system that supports the Murrelektronik M8 female cordset in demanding industrial conditions.
The manufacturer also calls out key resistance properties: flame behaviour tested to standards such as IEC 60332‑2‑2 and UL 1581 FT2, and oil resistance according to DIN EN 60811‑404. These characteristics mean that the Murrelektronik M8 female cordset can be deployed in control cabinets, machines, or lines where moderate oil exposure or flame‑propagation requirements exist. Taken together, these features show that the Murrelektronik M8 female cordset is more than just a generic extension; it’s a carefully specified cable assembly.
Installing the Murrelektronik M8 female cordset correctly
Even a well‑designed component can fail early if it’s installed badly. To get the most from a Murrelektronik M8 female cordset, you need to respect its torque, bending, and wiring guidelines. The manufacturer recommends a tightening torque of 0.4 N·m for the M8 screw coupling. Using an appropriate torque wrench—such as Murrelektronik’s dedicated M8 AF9 tool—helps ensure every Murrelektronik M8 female cordset on a machine is tightened consistently, reducing the risk of leakage or thread damage.
Bend radius is another critical parameter. For static applications, the minimum bending radius for the Murrelektronik M8 female cordset is 10 times the cable’s outer diameter. With a 4.6 mm OD, that means about 46 mm minimum. For dynamic applications, where the cable is flexing, the guideline is 15 times the diameter, or roughly 69 mm. Staying within these radii helps preserve the integrity of the insulation and jacket, protecting the Murrelektronik M8 female cordset from premature failure.
The manufacturer also emphasises strain relief and mechanical protection. Wherever the Murrelektronik M8 female cordset transitions from moving to fixed parts, or enters a cabinet, you should secure it with cable ties, clamps, or glands to prevent the connector from carrying mechanical loads. When combined with corrugated tube or drag‑chain systems, proper strain relief allows the Murrelektronik M8 female cordset to survive millions of motion cycles within its defined limits.
On the wiring side, the pin assignment is clearly documented: pin 1 is brown, pin 2 is white, pin 3 is blue, and pin 4 is black. However, this colour mapping only tells you how the Murrelektronik M8 female cordset is constructed internally, not what each core should do in your circuit. Many systems follow conventions such as brown = supply +, blue = supply −, and the remaining colours as signal lines, but you should always follow the device and PLC/I/O manuals. Mis‑assigning functions while using a Murrelektronik M8 female cordset can lead to very tricky faults.
The free cable end is designed to be stripped with about 20 mm of jacket removal, which exposes enough core length for easy termination. When you strip and ferrule the conductors of the Murrelektronik M8 female cordset, avoid nicking the copper strands and select ferrule sizes that match the 0.25 mm² cross‑section. Clean terminations and correct tightening torque at terminal blocks will help your Murrelektronik M8 female cordset maintain low contact resistance over its entire lifetime.
Choosing alternatives to the Murrelektronik M8 female cordset 7000-08061-2210500
Because the 7000-08061-2210500 article is now formally discontinued, a key question for many engineers is which replacement to choose. The Murrelektronik M8 female cordset ecosystem offers several close relatives that keep the same electrical interface while upgrading mechanical performance. Understanding these options lets you treat the original Murrelektronik M8 female cordset as a baseline and move toward more robust designs.
The most direct successor is typically referenced as 7000-08061-2310500. This alternative is still a Murrelektronik M8 female cordset in terms of interface—same M8 female straight A‑coded 4‑pole connector and 5 m length—but it uses a drag‑chain‑optimised cable. Bending‑life increases dramatically to around 10 million cycles, and the minimum bending radii are tightened to 5 × OD (fixed) and 10 × OD (dynamic). If you currently have machines with the original Murrelektronik M8 female cordset in moving applications, this upgraded version offers a substantial lifetime improvement.
In the 231‑type cable, the insulation is made from PP rather than PVC, and the design is explicitly halogen‑free. This gives the newer Murrelektronik M8 female cordset variants better performance in applications where halogen‑free materials are required or where cable flexibility and low‑temperature resistance are important. Some datasheets note static temperature ranges extending down to −40 °C, which widens the environmental envelope compared to the older Murrelektronik M8 female cordset design.
If torsion is part of the game—for example, robot wrists, rotary tables, or rotating tooling—the 7000-08061-2510500 variant is even more specialised. This robotics‑grade Murrelektronik M8 female cordset supports torsion stress around ±360° per metre with up to one million torsion cycles, on top of drag‑chain suitability. For applications where cables need to twist as well as bend, this Murrelektronik M8 female cordset successor significantly reduces the risk of core breakage or jacket fatigue.
There are also colour and jacket variants in the same family. For instance, certain part numbers offer black jackets with drag‑chain rating while keeping the same interface as the legacy Murrelektronik M8 female cordset. Colour options are useful when you need visual differentiation between power and signal runs, between safety circuits and standard IO, or between different machine sections where multiple Murrelektronik M8 female cordset assemblies share the same routing paths.
Alongside complete cordsets, it’s worth considering accessories and related components. Tooling such as torque‑limited wrenches helps ensure every Murrelektronik M8 female cordset is tightened correctly, while protective caps for unused M8 ports maintain IP integrity on enclosures. T‑couplers can split signals where appropriate, and field‑wireable M8 connectors let you build custom lengths or repair damaged cables while keeping compatibility with an installed Murrelektronik M8 female cordset base.
The key takeaway is this: if you’re working on a new design, lean toward the newer drag‑chain or robotics options rather than the original Murrelektronik M8 female cordset 7000-08061-2210500. You get the same interface and similar electrical ratings, but with far stronger mechanical performance and future‑proofed materials.
Where the Murrelektronik M8 female cordset fits in your machine
So where does a Murrelektronik M8 female cordset usually sit in a real‑world installation? In many plants, you’ll find this type of assembly bridging the gap between field‑mounted sensors or actuators and the fixed control hardware. The M8 female connector mates with proximity switches, photoelectric sensors, or compact actuators, while the flying leads terminate into IO modules, junction boxes, or cabinet terminals. In that role, a Murrelektronik M8 female cordset becomes a small but vital link in the automation chain.
M8 connectors are often chosen for compact, low‑power devices, whereas M12 interfaces dominate higher‑power or more ruggedised equipment. That means a Murrelektronik M8 female cordset is commonly associated with signal‑level tasks—sensing position, speed, presence, or simple binary states. Yet the 4 A contact rating still gives the Murrelektronik M8 female cordset enough capability to handle small loads or valve coils, provided the overall circuit is designed with appropriate protection and fusing.
Because the assembly offers high IP protection ratings when correctly tightened, it is well suited for environments where dust, humidity, or washdown is a concern. Packaging machines, material‑handling systems, sorting lines, and light assembly cells are all examples where a Murrelektronik M8 female cordset can provide reliable connectivity. When routed through cable chains and protected by conduit, the Murrelektronik M8 female cordset can handle moderate movement without sacrificing sealing or electrical integrity.
The flexibility and moderate size of the cable make it easier to route through tight spaces than larger industrial cables. In cramped junction boxes or compact machine frames, being able to bend and dress a Murrelektronik M8 female cordset neatly is a real advantage. Combined with the clear colour coding of the cores, this also simplifies troubleshooting and retrofits, especially when multiple Murrelektronik M8 female cordset assemblies share the same harness.
Ultimately, the value of this component lies in its predictability. Once you know the limits and behaviour of a Murrelektronik M8 female cordset, you can treat it like a standard building block across many machines and projects. Whether you stick with legacy installations or migrate toward newer variants, the same principles apply.
