Telemecanique XUK2ARCNL2T Photoelectric Sensor: Technical Overview

The Telemecanique XUK2ARCNL2T photoelectric sensor is a through-beam transmitter from the XU XUK photoelectric sensor range. It is designed to emit the light beam used by a compatible receiver for object detection. In a through-beam system, the transmitter and receiver are installed opposite each other. When an object passes between them and blocks the beam, the receiver detects the change and sends a signal to the control system.

This model is used in industrial environments where stable long-distance detection is required. It is especially useful in applications where the target object may have different colors, surface textures, or reflectivity levels. Since the sensing principle depends on beam interruption, the system can provide dependable operation in many production and handling processes.

Telemecanique XUK2ARCNL2T Technical Characteristics

The XUK2ARCNL2T is a compact 50 x 50 photoelectric transmitter with a plastic housing. It belongs to the general purpose single mode sensor family and is designed for through-beam detection. It supports 24…240 VAC/DC supply, which allows it to be integrated into a wide range of industrial electrical systems.

The sensor uses a 2-wire wiring technique and is supplied with a 2 m cable. This fixed cable format is practical for installations where direct wiring is preferred and where the device is expected to remain mounted in a stable position for long service periods.

Application Areas

The Telemecanique XUK2ARCNL2T photoelectric sensor is typically used with a receiver such as a matching XUK through-beam receiver. Together, the pair can be used for package detection, part counting, conveyor monitoring, machine entry detection, and product flow verification.

Through-beam transmitters are often chosen for applications requiring higher detection reliability over longer distances. They are also suitable where reflective sensing may be affected by product color, gloss, transparency, or surface irregularity.

Installation Guidance

For best performance, the transmitter should be mounted directly facing the receiver. Alignment should be checked during commissioning and after mechanical adjustments to the machine. The optical face should remain clean, especially in dusty, oily, or high-particle environments. Cable routing should avoid sharp bends, crushing points, and high-noise power cables where possible.

Because this device is a transmitter, it does not provide the main object detection output by itself. The receiver in the sensing pair provides the switching signal. For more background on related products, visit Telemecanique information.

Telemecanique XUK2ARCNL2T FAQ

What is the Telemecanique XUK2ARCNL2T photoelectric sensor?

It is a through-beam photoelectric transmitter used with a compatible receiver to create an object detection system.

Does the XUK2ARCNL2T detect objects by itself?

No. It emits the beam, while the receiver detects beam interruption and sends the output signal.

What supply voltage does it use?

The XUK2ARCNL2T supports 24…240 VAC/DC, making it suitable for different industrial control voltage environments.

What connection type does this model have?

It has a 2 m cable connection and uses a 2-wire wiring technique.

Where is this transmitter commonly installed?

It is commonly installed on conveyors, packaging machinery, handling systems, counting stations, and production equipment requiring through-beam detection.

Why use a through-beam transmitter and receiver pair?

A through-beam pair can provide stable detection over longer distances and can be less affected by target color or surface finish than diffuse sensing methods.
