Telemecanique XUB2APXNL2R Photoelectric Sensor Receiver Guide

The Telemecanique XUB2APXNL2R photoelectric sensor receiver is an M18 cylindrical thru-beam receiver from the Telemecanique Photoelectric Sensors XU range. It is designed for industrial automation systems where a separate transmitter sends a light beam and the receiver detects whether that beam is present or interrupted. This sensing principle is valued in production environments because it provides stable object detection over longer distances and is less affected by the surface color or reflectivity of the detected object.

The XUB2APXNL2R is particularly useful in conveyor systems, packaging lines, sorting equipment, automated transfer machines, counting points, and object presence detection tasks. Its compact cylindrical body allows it to fit into machine frames and tight mounting areas while still providing a strong optical detection range.

Technical Profile

This model is a photo-electric sensor receiver with a plastic cylindrical M18 design. It uses a thru-beam detection system and is rated for a maximum sensing range of 30 m, with a nominal sensing distance of 20 m when paired with the correct transmitter. The sensor has an axial line of sight, meaning the optical path is aligned straight through the sensor body. This makes it suitable for installations where the transmitter and receiver face each other directly across a conveyor, gate, or process zone.

The XUB2APXNL2R operates on a 12…24 V DC supply and uses a PNP output. It has a 4-wire configuration and provides discrete switching output. The unit is supplied with a 2 m cable, making it useful where direct wiring is preferred over connector-based installation. Cable versions are often selected for fixed installations where the sensor location is stable and the wiring route is already defined.

Speed, Adjustment, and Reliability

One of the notable strengths of the XUB2APXNL2R is its fast response behavior. With a response time of approximately 0.5 ms and a high switching frequency, it can support applications involving fast-moving products or frequent detection cycles. The sensor includes sensitivity adjustment, typically through a potentiometer, allowing the installer to fine-tune detection behavior according to beam alignment, distance, and environmental conditions.

Electrical protection features such as reverse polarity protection, overload protection, and short-circuit protection help improve system reliability during installation and operation. These safeguards are important in industrial control panels and field wiring, where incorrect connections or transient faults can otherwise damage sensor electronics.

Environmental Design

The sensor is designed for demanding production areas and carries IP65 and IP67 protection ratings. These ratings support use in environments with dust and moisture exposure, provided the cable entry and installation are handled correctly. The operating temperature range from -30 °C to 55 °C supports a broad range of factory and equipment conditions.

Best-Fit Applications

The XUB2APXNL2R is suitable for long-distance detection across conveyors, object counting, gap detection, carton detection, pallet detection, and automated process monitoring. Because it is a receiver, it must be used with a compatible transmitter. Proper alignment is essential, especially when using the full sensing range.
