With its unique design, wide sensing area, and compatibility with Omron’s advanced amplifier units, the E32-T16WR has become a go-to option for manufacturers worldwide.
This article provides an in-depth look at the Omron E32-T16WR, covering its features, technical specifications, compatible amplifiers, common applications, and alternative models. Whether you are considering this sensor for a new system or upgrading an existing setup, this comprehensive guide will help you understand why the E32-T16WR is an exceptional solution.
What is the Omron E32-T16WR?
The Omron E32-T16WR is a fiber optic through-beam sensor unit designed to deliver highly accurate object detection in industrial environments. Unlike conventional single-point sensors, it provides a 30 mm sensing height—essentially creating a mini light curtain that ensures reliable detection even when object positions vary. Combined with a sensing distance of up to 4000 mm, it is ideal for applications where consistent and robust detection is critical.
This sensor unit uses flexible, high-bend radius plastic fibers encased in PVC sheathing. The fibers are free-cut, which means users can trim the standard 2-meter length to meet installation requirements. Designed for compact machinery and automation setups, the E32-T16WR is both space-efficient and highly adaptable.
Key Features of the Omron E32-T16WR
1. Through-Beam Sensing Method
The through-beam design consists of a paired emitter and receiver. When an object interrupts the beam between them, the sensor triggers detection. This method is known for its accuracy and reliability, especially in environments with varying object sizes and positions.
2. Wide 30 mm Sensing Area
Unlike traditional sensors that rely on a single-point beam, the Omron E32-T16WR offers a 30 mm tall detection field. This makes it ideal for detecting objects that may tilt, bounce, or shift position while moving on conveyors or processing lines.
3. Long Sensing Distance
With a maximum range of 4000 mm (4 m), this sensor can be deployed across wide conveyor belts or production lines. Pairing it with high-performance amplifiers ensures stable detection even at maximum distances.
4. Flexible and Free-Cut Fiber
The fiber is constructed from plastic with a PVC sheath, offering a minimum bending radius of just 1 mm. This extreme flexibility allows installation in tight spaces where conventional fiber sensors cannot be routed. Since the fibers are free-cut, installers can trim them to custom lengths, reducing installation complexity.
5. Robust Build
The square-shaped sensor head is constructed from durable ABS material, ensuring long-lasting use. Its IP50 rating provides dust protection, making it suitable for most factory environments, though it should not be used in wet or oily conditions.
6. Wide Operating Temperature Range
Operating between -25°C and +55°C, the E32-T16WR withstands the varying temperatures of industrial settings, ensuring stable performance in production environments.

Compatible Amplifiers for the Omron E32-T16WR
The E32-T16WR is a passive fiber unit and requires a fiber optic amplifier for operation. Omron provides a range of amplifiers designed for seamless compatibility.
1. Omron E3NX-FA Series
This is the recommended amplifier for the E32-T16WR. It features twin digital displays, Smart Tuning, and extended detection ranges. With the E3NX-FA, the E32-T16WR can achieve nearly its full 4 m sensing distance in standard mode.
2. Omron E3X-HD Series
A user-friendly option with one-touch auto-tuning. It works well with the E32-T16WR, though the maximum sensing distance is slightly reduced compared to the E3NX-FA.
3. Other Supported Amplifiers
The E32-T16WR is also compatible with:
● E3NX-CA
● E3X-DA-S
Adapters such as the E39-F9-7 thin fiber attachment may be required when using older amplifiers.
Applications of the Omron E32-T16WR
The versatility of the Omron E32-T16WR makes it ideal for a wide range of industrial applications. Its wide sensing area and reliable through-beam detection ensure it can handle challenging environments where other sensors may fail.
1. Conveyor Line Monitoring
Perfect for detecting objects moving across production lines, especially when their position or alignment varies. It is often used in functions such as counting items travelling down a conveyor line.
2. Detecting Small Components
Its ability to detect objects as small as 0.3 mm makes it suitable for quality control applications such as checking for missing chips or small components.
3. Objects with Holes or Irregular Shapes
Because of its 30 mm sensing field, objects with holes or cutouts can still be detected reliably, preventing false negatives.
4. Packaging and Sorting
The E32-T16WR ensures that all products passing through a line are detected, regardless of tilt, size variation, or minor misalignment.
5. Mini Light Curtain Substitute
In tight spaces where traditional light curtains cannot fit, the E32-T16WR acts as a miniature alternative for area detection.
Alternatives to the Omron E32-T16WR
While the E32-T16WR is highly versatile, Omron offers a range of similar models tailored to specific needs.
1. E32-T16WR 5M
Same specifications but with a longer 5 m fiber length for installations requiring greater amplifier-to-sensor distance.
2. E32-T16W 2M
A 30 mm area sensor with standard fiber (less flexible than the WR version). Suitable when extreme flexibility is unnecessary.
3. E32-T16PR 2M
Provides an 11 mm sensing height for more precise area detection. Uses flexible fiber.
4. E32-T16JR 2M
An 11 mm area sensor with side-view orientation, useful in installations where a top-view sensor is not practical.
5. E32-D36P1 2M
A reflective type area sensor with 11 mm sensing height. Best for single-sided detection when installing both emitter and receiver is not possible.
