The SICK WL45-P250 (Part No. 1008840) is a versatile and durable retro-reflective photoelectric sensor from SICK’s established W45 series. Engineered to deliver reliable long-range object detection, it combines advanced sensing technology, rugged construction, and flexible electrical integration, making it suitable for a broad range of industrial automation applications.

One of its most practical features is the visible red LED light source, which makes installation and alignment quick and straightforward. The red beam provides a clear visual guide, enabling precise positioning and reducing setup time. With a sensing range of up to 30 m, the WL45-P250 is well suited for demanding tasks such as monitoring conveyor systems, detecting objects in automated storage areas, or ensuring reliable presence detection in production lines.

The sensor is equipped with a PNP transistor output, supporting both light-on and dark-on switching modes. This allows system designers to configure the sensor according to the logic needed for their application. Whether detecting an object’s presence by beam interruption (dark-on) or absence (light-on), the WL45-P250 provides consistent and accurate output signals. This flexibility makes it adaptable to many machine control scenarios, from counting items to initiating automated processes.

Durability and reliability are key strengths of the WL45-P250. It features a PG13.5, 6-pin terminal-chamber connection, which ensures secure wiring and protects against dust, vibration, and moisture. Combined with its rugged housing, this design makes the sensor highly resistant to challenging conditions commonly found in industrial environments such as packaging plants, material handling systems, and assembly operations.

Electrically, the WL45-P250 offers broad compatibility thanks to its wide operating voltage range of 10 V to 60 V DC. This flexibility simplifies integration into different electrical infrastructures without the need for additional modifications. Furthermore, the sensor boasts a fast response time of approximately 1.2 ms, ensuring accurate detection of fast-moving objects. This responsiveness is especially valuable in high-speed production environments, where precision and timing are critical to efficiency and reliability.

Physically, the WL45-P250 is compact yet robust, allowing for easy installation in confined spaces without compromising strength or durability. The visible light beam provides a user-friendly alignment method, while the rugged construction ensures long-term stability and reduces the need for frequent maintenance.
