Overview of the SICK WTA24-P5201 Distance Sensor
At its core, the SICK WTA24-P5201 distance sensor is a photoelectric distance sensor that uses a triangulation principle with an infrared LED to measure the distance to a target. The SICK WTA24-P5201 distance sensor focuses on a short measuring range of 250…350 mm, with a capture range of 200…250 mm where it can reliably detect an object and start tracking its distance.
This SICK WTA24-P5201 distance sensor is part of SICK’s WTA24 family, which shares the same compact metal housing and general architecture but offers different ranges for different tasks. What sets the SICK WTA24-P5201 distance sensor apart is its sweet spot in close-range precision sensing: it’s ideal when your target is always relatively near, such as products on a conveyor, coils, rolls or level surfaces in bins and hoppers.
In one device, the SICK WTA24-P5201 distance sensor provides:
- A 4–20 mA analog output proportional to distance
- Two programmable PNP switching outputs (Q1 and Q2)
- Fast response time of around 5 ms
- A robust IP67-rated metal housing
- M12, 5-pin connection for easy wiring
These features make the SICK WTA24-P5201 distance sensor a smart choice when you need both measurement and presence detection without adding separate analog and switching sensors.
How the SICK WTA24-P5201 Distance Sensor Measures Distance
The SICK WTA24-P5201 distance sensor uses a tried-and-tested optical triangulation method to measure distance. Inside the SICK WTA24-P5201 distance sensor, an infrared LED emits a beam of light toward the target surface. The reflected light returns through a lens system and lands on a position-sensitive detector. As the target moves closer or farther away, the position of the light spot on the detector shifts, and the SICK WTA24-P5201 distance sensor electronics convert this shift into a distance value.
Because the SICK WTA24-P5201 distance sensor measures geometry rather than just intensity, it can deliver more stable readings than simple diffuse sensors that only look at brightness. This makes the SICK WTA24-P5201 distance sensor less sensitive to changes in target colour or reflectivity, especially within its specified range. Accuracy and repeatability are typically within a few millimetres, especially on light or neutral surfaces.
In normal operation, the SICK WTA24-P5201 distance sensor updates its outputs with a response time of roughly 5 ms, corresponding to a switching frequency of about 100 Hz. That’s fast enough for many conveyor-based applications, level detection tasks, and positioning jobs where the SICK WTA24-P5201 distance sensor is tracking moderate-speed motion.
Key Technical Specifications of the SICK WTA24-P5201 Distance Sensor
To choose and correctly apply the SICK WTA24-P5201 distance sensor, it helps to understand its core technical data. Below is a breakdown of the most important specs of the SICK WTA24-P5201 distance sensor and what they mean in practice.
Measuring range and capture range
The SICK WTA24-P5201 distance sensor offers:
- Measuring (scanning) range: 250…350 mm
- Capture range: 200…250 mm
Within the capture range, the SICK WTA24-P5201 distance sensor can reliably detect that a target is present and begin distance measurement. Between 250 and 350 mm, the analog output of the SICK WTA24-P5201 distance sensor is linearised to reflect distance with good resolution. For best performance, you should design your mechanics so that the target remains within this working window whenever you expect valid readings from the SICK WTA24-P5201 distance sensor.
Electrical characteristics
The SICK WTA24-P5201 distance sensor runs on 12…30 V DC, which fits standard industrial control voltages. Current consumption without load is under 100 mA, meaning the SICK WTA24-P5201 distance sensor is easy to power from most PLC or control panel supplies.
The analog output of the SICK WTA24-P5201 distance sensor is a 4–20 mA current loop. This output is designed to drive a load of 0…500 Ω, making it straightforward to connect the SICK WTA24-P5201 distance sensor to PLC analog inputs, process controllers or display units designed for 4–20 mA signals.
Output configuration
The SICK WTA24-P5201 distance sensor features two PNP switching outputs, Q1 and Q2, plus the 4–20 mA analog output. Each PNP channel of the SICK WTA24-P5201 distance sensor can switch up to 100 mA, enough for PLC inputs, small relays or indicator lamps. These outputs are reversible via teach-in, meaning you can configure the SICK WTA24-P5201 distance sensor so that the output turns ON when the distance is greater than a threshold, or ON when the distance is less than that threshold.
Mechanical design and housing
The compact metal body of the SICK WTA24-P5201 distance sensor measures roughly 27 × 88 × 65 mm (W × H × D) and weighs around 0.4 kg. The robust housing of the SICK WTA24-P5201 distance sensor is either stainless steel or nickel-plated brass, giving excellent resistance to mechanical shock and vibration.
With an IP67 rating, the SICK WTA24-P5201 distance sensor is dust-tight and protected against temporary immersion in water. That means the SICK WTA24-P5201 distance sensor can survive washdowns, splashes and dusty environments, as long as the M12 connector and cable are properly sealed.
Environmental ratings
The SICK WTA24-P5201 distance sensor operates from –10 °C to +55 °C, with a storage range of –25 °C to +75 °C. These ranges allow the SICK WTA24-P5201 distance sensor to be installed in many standard indoor and light outdoor industrial settings. For high-temperature areas, you can pair the SICK WTA24-P5201 distance sensor with cooling plates or shields to keep its housing within rated limits.
Analog and Switching Outputs on the SICK WTA24-P5201 Distance Sensor
A major advantage of the SICK WTA24-P5201 distance sensor is the combination of one analog output and two digital switching outputs in the same package. This lets you design flexible control schemes around the SICK WTA24-P5201 distance sensor without adding extra sensors.
The 4–20 mA analog output of the SICK WTA24-P5201 distance sensor continuously represents the measured distance across the usable range. For example, 4 mA might correspond to 250 mm and 20 mA to 350 mm, with the SICK WTA24-P5201 distance sensor interpolating values in between. Your PLC or controller can use this to calculate actual distance, log measurements over time, or regulate position, level or thickness.
The Q1 and Q2 outputs of the SICK WTA24-P5201 distance sensor act as threshold switches. Using teach-in, you assign a switching point for each output, such as “object closer than 320 mm” or “object farther than 270 mm.” The SICK WTA24-P5201 distance sensor then drives each PNP output high or low according to your configuration, allowing simple min/max or in-window monitoring. Because the SICK WTA24-P5201 distance sensor supports reversible switching, it’s straightforward to adapt logic to suit your PLC program conventions.
This blend of continuous and discrete feedback allows the SICK WTA24-P5201 distance sensor to serve multiple roles: a precise measuring device, a simple presence sensor, and a watchdog for minimum and maximum levels or positions.
Mounting and Installation Guidelines for the SICK WTA24-P5201 Distance Sensor
Correct mechanical installation is crucial to getting accurate readings from the SICK WTA24-P5201 distance sensor. The metal housing of the SICK WTA24-P5201 distance sensor includes two M5 threaded holes (6 mm deep) so you can mount it securely on machine frames, brackets or panels.
