Telemecanique XUB1BPANL2 Photoelectric Sensor: Technical Guide

The Telemecanique XUB1BPANL2 photoelectric sensor is a cylindrical M18 reflex sensor from the Telemecanique XU range. It is designed for industrial object detection where a stable optical beam, compact metal housing, and straightforward installation are required. This model uses a reflex detection system, which means it works with a reflector and detects an object when the light path is interrupted. Its nominal sensing distance is 4 m with reflector XUZC50, while the sensing range is listed as greater than 1 m up to 5 m.

Telemecanique XUB1BPANL2 Technical Profile

XUB1BPANL2 has a nickel-plated brass enclosure, PMMA lens, axial line of sight, and infrared reflex emission. It operates on 12…24 V DC with reverse polarity protection and has supply voltage limits of 10…36 V DC. The sensor uses a 3-wire DC wiring technique, PNP discrete output, and one normally open output function. Electrical connection is made through a 2 m cable, which is practical for fixed machine wiring where a direct cable exit is preferred over a detachable connector.

The switching frequency is 500 Hz, with 1 ms response and recovery delays. Current consumption is 35 mA with no load, and switching capacity is up to 100 mA with overload and short-circuit protection. These values make the sensor suitable for conveyors, counting points, packaging equipment, transfer lines, and position-checking stations where objects pass through a defined beam path.

Industrial Use and Installation

In a reflex photoelectric arrangement, the sensor and reflector face each other. The sensor emits infrared light toward the reflector and monitors the returned signal. When a box, panel, component, or other target interrupts the beam, the output changes state. This makes the Telemecanique XUB1BPANL2 photoelectric sensor useful for presence detection, object counting, gate monitoring, and automated handling control.

Because this model is built in an M18 cylindrical form, it can be mounted in standard brackets, threaded holes, or compact machine frames. The metal enclosure gives it a strong mechanical profile for production environments. Its IP65 and IP67 protection ratings support use in dusty or wet industrial areas, while vibration resistance of 7 gn and shock resistance of 30 gn help maintain stability around moving machinery.

Important Selection Notes

When selecting this sensor, engineers should confirm the output type, cable preference, supply voltage, reflector position, sensing distance, and environmental exposure. The PNP output is commonly used with many industrial PLC input systems. The normally open output function is useful when the control system expects a signal only when the object is detected.

The manufacturer lists this model as end of commercialization, with XUB9BPXNL2 identified as the replacement. For existing machinery, XUB1BPANL2 remains an important reference for maintenance, documentation, spare-part mapping, and technical troubleshooting. For new projects, checking the replacement model is recommended.

Telemecanique XUB1BPANL2 FAQ

What is the Telemecanique XUB1BPANL2 used for?

It is used for non-contact object detection in industrial automation, especially on conveyors, packaging lines, handling systems, and machine stations where a target passes between a sensor and reflector.

What type of detection does XUB1BPANL2 use?

It uses reflex photoelectric detection. The sensor sends infrared light to a reflector and detects beam interruption when an object crosses the optical path.

What is the sensing distance?

The nominal sensing distance is 4 m with reflector XUZC50. The listed sensing range is greater than 1 m up to 5 m, depending on setup and conditions.

Does this sensor have a connector?

No. XUB1BPANL2 is supplied with a 2 m cable. This can be suitable for permanent machine wiring where fewer detachable points are preferred.

Is XUB1BPANL2 still active?

The manufacturer marks it as end of commercialization and lists XUB9BPXNL2 as the replacement. It may still appear in maintenance records and existing equipment documentation.
