Product Description

SICK WLG4S-3P5232H is a high-performance retroreflective photoelectric block sensor designed for industrial and automation applications requiring precise detection of transparent and difficult-to-detect objects. With a long detection range of 5 meters and a PNP output type, it delivers reliable and stable sensing performance even in challenging environments.

The sensor features a robust stainless steel housing specifically designed under the W4S-3 Inox Hygiene Glass series, making it suitable for use in industrial processes where hygiene and corrosion resistance are critical. A PinPoint LED light source provides a small, intense light spot that facilitates easy alignment and quick installation. The sensor’s single-lens autocollimation system enables detection of very small gaps, transparent films, and vials with optical defects.

Operating temperature ranges from -30°C to 60°C, this sensor is also certified to IP66, IP67, IP68, and IP69K ingress protection ratings, allowing it to withstand dust, water immersion, and even high-pressure cleaning. The simple push-button teach-in functionality enables quick threshold adjustment to adapt automatically to changing environmental conditions such as dust or temperature variations.

The sensor supports flexible configuration via cable or IO-Link (in some variants), offering advanced diagnostics and monitoring options to reduce downtime and simplify maintenance. Standardized safety certifications including UL, cUL, and FDA approvals further confirm the sensor’s conformity for demanding industrial environments.

Reliable detection of transparent objects and small gaps. Robust stainless steel construction for food and hygiene industries. High ingress protection makes it ideal for harsh industrial conditions. Fast response time of 500 μs supports high-speed automation tasks.

Simple teach-in button for ease of use and quick commissioning. Flexible integration with 4-pin M8 connector interface.

This sensor is widely utilized across automation, manufacturing, packaging, pharmaceutical, and food processing industries where accurate object detection is vital. Convenient mounting via shaft mount and durable IP ratings ensure long service life and dependable performance. The WLG4S-3P5232H retroreflective sensor is an optimal choice for transparent object sensing and robust industrial sensor applications.
