Description

The SICK WL4SLG-3P2232 is a precision miniature photoelectric sensor engineered for industrial automation and object detection applications. Part of SICK’s W4 sensor family, it operates on the principle of retro-reflective autocollimation, allowing it to detect objects reliably over distances up to 4.5 meters without requiring a separate reflector.

Featuring a visible red laser light source (650 nm) with a polarized filter and a compact rectangular housing, this sensor delivers high accuracy and repeatability even with small, transparent, or glossy objects. The device includes a single teach-in button for simple commissioning, a PNP complementary output for easy interfacing with control systems, and a fast response time (< 0.5 ms) with a switching frequency up to 1 kHz for dynamic processes.

Built to withstand demanding environments, the WL4SLG-3P2232 is housed in rugged Novodur plastic rated IP66/IP67, making it resistant to dust, water ingress, and vibration. The sensor is powered from 10 V DC to 30 V DC, draws approximately 30 mA, and connects via an M8 4-pin male connector for easy installation. Its compact dimensions and robust performance make it ideal for conveyor systems, packaging lines, robotics, and other automated industrial settings.
