SICK Retroreflective Photoelectric Sensor Block Sensor 5 m PNP 30V DC 100mA IP66 IP67 IP69K WL9M4-3P2234

SICK WL9M4-3P2234 Retroreflective Photoelectric Sensor Block Sensor features a robust plastic housing designed for precise detection of small objects and object features in industrial automation environments. Operating at up to 30V DC with a maximum current of 100 mA, it ensures reliable and stable sensing performance.

This sensor supports a detection range of 5 meters with LED light source technology, delivering high accuracy and quick response time of 500 microseconds. The retroreflective detection type enables sensing even through small openings or transparent objects, making it ideal for applications such as presence detection, edge monitoring, and transport of transparent materials.

Engineered for harsh industrial environments, the sensor is protected by IP66, IP67, and IP69K ratings, safeguarding it against dust ingress, water jets, and high-pressure washdowns. Its rugged VISTAL® housing offers exceptional mechanical resistance and longer service life.

The sensor includes an M8 4-pin connector terminal type for straightforward and versatile installation options. Compliance with UL and EN IEC hazardous area certifications further underscores its suitability for critical industrial operations.

Typical applications include paper stack height measurement, sheet presence and position checking, tool monitoring, fiber break monitoring, and presence detection in ultrasonic welding stations. The W9 series from SICK is a comprehensive family of Photoelectric Sensors, combining innovative SIRIC® technology to suppress optical and electromagnetic interference in any environment.
