SICK WL280-2H4331 PHOTOELECTRIC SENSORS

The SICK WL280-2H4331 is a compact, high-performance photoelectric retro-reflective sensor designed for reliable object detection in industrial automation and control applications. It belongs to the SICK W280-2 series and uses a visible red LED light source to detect objects with the help of a reflector. The sensor provides a maximum sensing range of up to 15 metres, depending on the reflector used, making it suitable for material handling, packaging systems, conveyor belts, production lines, and automated machinery.

This sensor features a dual-lens optical system and a rectangular housing design for convenient installation in industrial environments. Its sensitivity can be adjusted using an integrated potentiometer, allowing users to adapt the detection performance to different operating conditions. The light-on switching function enables the sensor to respond when the reflected light beam is received. Its relay output supports flexible integration with suitable industrial control circuits.

The WL280-2H4331 operates with a wide supply voltage range of 24–240 V AC/DC, offering flexibility for different electrical installations. Its compact dimensions of 23.5 mm × 74.5 mm × 63 mm help simplify mounting in space-constrained applications. The sensor uses a cable-gland connection and is designed for dependable operation in industrial automation systems.

The visible red light spot makes alignment and commissioning easier. The retro-reflective operating principle helps detect objects passing between the sensor and reflector, supporting reliable monitoring of products and materials. A reflector (P250) and mounting bracket (BEF-W280) are included in the specified delivery package.
