The SICK WL4S-3P2230V (part number 1045095) is a high-performance photoelectric retro-reflective sensor from SICK’s W4S-3 Inox series, designed for precise object detection in industrial applications. With an adjustable sensing range from 0 meters to 4 meters, this sensor offers flexibility to accommodate various application requirements, making it suitable for diverse industrial environments.

Equipped with a visible red LED light source emitting at 650 nm, the sensor provides a focused light spot with a diameter of approximately 45 mm at a 1.5-meter distance. This feature ensures precise detection and simplifies alignment, enhancing setup accuracy.

The sensor operates with a supply voltage of 10–30 V DC and features a PNP output with light/dark switching mode. Its high switching frequency of 1,000 Hz ensures reliable detection of fast-moving objects, making it suitable for high-speed applications. The response time of ≤ 0.5 ms allows for quick detection of changes in the detection field.

Designed for durability, the WL4S-3P2230V features a compact rectangular housing measuring 15.3 mm x 22.2 mm x 44.5 mm. Constructed from stainless steel V4A (1.4404, 316L), the housing provides resistance to mechanical stress and environmental factors, making it suitable for use in harsh industrial settings. The sensor is also equipped with an M8 4-pin male connector, facilitating easy integration into existing systems.
