Telemecanique XUBTAPSNL2 Photoelectric Sensor Technical Guide

The Telemecanique XUBTAPSNL2 photoelectric sensor is an industrial detection device from the Telemecanique XU range, developed for reliable object sensing in automated environments. This model is a cylindrical M18 photoelectric sensor with a polarised reflex detection system, designed for applications where stable object recognition and compact installation are required.

Technically, the XUBTAPSNL2 operates with a 12 to 24 VDC supply and uses a 2 m cable connection. It features a PNP discrete output, programmable NO or NC function, and a sensing range associated with polarised reflex operation. The sensor is particularly suitable for packaging, transparent object detection, conveyor monitoring, and industrial automation tasks where repeatable non-contact sensing is essential.

What Is the Telemecanique XUBTAPSNL2 Photoelectric Sensor?

The Telemecanique XUBTAPSNL2 photoelectric sensor detects objects by using a coaxial polarised red reflex light beam. In this type of system, the sensor sends light toward a reflector and evaluates the returned signal. When an object interrupts or changes the reflected light, the output state changes and the control system receives a detection signal.

This method is widely used because it allows both the emitter and receiver to be housed in one compact body. Compared with through-beam designs, polarised reflex sensors are easier to mount because only the sensor and reflector need alignment. The polarised optical principle also helps reduce false detection from shiny surfaces.

Main Technical Characteristics

The XUBTAPSNL2 belongs to the Telemecanique Photoelectric Sensors XU range and uses the XUBT sensor name. Its cylindrical M18 plastic body, PBT enclosure, 3-wire connection, and DC supply circuit make it suitable for standard industrial machine layouts. The electrical design includes reverse polarity protection, a solid-state output, and overload and short-circuit protection.

The sensor is designed with a programmable output function, allowing one normally open or one normally closed output configuration. This flexibility helps engineers match the sensor behavior to PLC input logic, machine safety concepts, or process monitoring requirements.

Industrial Applications

The Telemecanique XUBTAPSNL2 photoelectric sensor is often used in packaging equipment, conveyor lines, filling machines, labeling machines, material handling systems, and object detection points where contactless sensing improves reliability. Its polarised reflex design is also relevant for transparent object detection, especially when products such as bottles, containers, films, or clear packaging materials need to be monitored.

Because the sensor uses a cable connection, it can be installed in applications where a fixed wiring layout is preferred. This is useful in machines where vibration, movement, or washdown-related conditions require secure cabling.

Installation Notes

Correct alignment between the sensor and reflector is important. The optical path should remain clean and free from obstruction. During installation, engineers should confirm the supply voltage, PNP input compatibility, cable routing, and mechanical mounting position. In high-vibration environments, stable mounting brackets help preserve alignment over time.

The sensor also provides environmental protection suitable for industrial locations, including IP65 and IP67 ratings. This makes it appropriate for many factory settings where dust, splashing water, or routine cleaning may occur.
