Telemecanique XU9M18MB230 Photoelectric Sensor: Detailed Technical Guide

The Telemecanique XU9M18MB230 photoelectric sensor is an M18 cylindrical sensor from the Telemecanique XU series, engineered for industrial object detection using a polarized reflex detection system. It is designed for applications that require stable detection, compact installation, and compatibility with both AC and DC supply systems.

This sensor uses red polarized reflex emission and works with a reflector, typically the XUZC50, to detect objects interrupting or changing the reflected light path. Its metal construction, axial optical alignment, and discrete output signal make it a dependable option for packaging, conveying, handling, and general automation systems.

Telemecanique XU9M18MB230 Main Technical Specifications

The XU9M18MB230 has a cylindrical M18 design, a nickel-plated brass enclosure, and a PMMA lens. Its nominal sensing distance is 2 m when used in polarized reflex mode with the appropriate reflector. Under suitable operating conditions, the maximum sensing distance is 3 m.

The sensor is supplied with a 2 m cable and uses a 2-wire wiring technique. It supports a rated voltage of 24 to 240 V AC/DC, with voltage limits from 20 to 264 V AC/DC. This wide operating range allows the sensor to be used across many control panel designs without requiring major electrical changes.

Telemecanique XU9M18MB230 Normally Closed Output Function

The most important functional difference of the Telemecanique XU9M18MB230 photoelectric sensor is its 1 NC output function. In a normally closed configuration, the output state is active under normal conditions and changes when the detection condition occurs. This can be useful in applications where fail-safe behavior, signal continuity, or specific control logic is required.

The solid-state output supports a switching capacity of 10 to 200 mA, with a switching frequency up to 25 Hz. The response delay and recovery delay are each 20 ms, making the sensor suitable for general-speed industrial detection tasks.

Industrial Design and Durability

The XU9M18MB230 is built for demanding environments. It operates between -25 °C and 55 °C and can be stored between -40 °C and 70 °C. It carries an IP67 protection rating, supporting reliable operation where dust and moisture exposure may be present.

For setup and maintenance, the device includes a yellow LED for output state and a red LED for instability. These visual indicators make alignment and troubleshooting easier, particularly when installing the sensor on conveyors, automated cells, or machinery where quick diagnostics are important.

Best Application Areas

This sensor is suitable for object presence detection, product counting, conveyor monitoring, packaging automation, and part positioning. Its polarized reflex technology is especially helpful where standard reflex sensing may be affected by shiny surfaces or background reflections.

The Telemecanique XU9M18MB230 photoelectric sensor is often selected when engineers need a compact M18 sensor with AC/DC supply flexibility and normally closed output behavior. For more background on the brand and related devices, visit Telemecanique information.
