The Sick 1056725 (Model WTB12-3P2441S59) is a robust, high-precision through-beam photoelectric sensor designed for reliable long-distance object detection in industrial automation. As part of the WTB series, this sensor combines accurate detection, rugged construction, and flexible installation options, making it ideal for applications such as conveyor monitoring, packaging, material handling, and high-speed production lines.

A standout feature of the WTB12-3P2441S59 is its extended sensing range of up to 30‚ÄØm, which enables it to detect objects over long distances with high reliability. Using a through-beam principle with separate emitter and receiver units, the sensor provides consistent performance even in challenging industrial environments with dust, vibration, or ambient light variations. Its long detection range makes it especially suitable for large-scale production lines and automated material handling systems.

The sensor incorporates PinPoint visible red LED technology, producing a highly concentrated, bright light spot. This allows for fast and precise alignment during installation, minimizing setup time and ensuring accurate detection. The sharp LED beam also improves detection reliability for small, dark, or reflective objects, which is essential for high-speed and high-precision automation applications.

Durability is another key advantage of the WTB12-3P2441S59. Its IP67-rated housing protects against dust, water, and other environmental hazards, allowing it to perform reliably in harsh industrial settings. The M12 connector provides a secure and standardized electrical connection, simplifying integration into control systems and reducing installation complexity. This combination of rugged housing and reliable connectivity ensures long-term operational stability and minimizes maintenance needs.

Electrically, the sensor features a PNP output and supports both Light On and Dark On switching modes, providing flexibility for various automation system configurations. Its fast response time allows accurate detection of high-speed moving objects, making it ideal for conveyors, automated sorting, and packaging operations. Operating within a 10 V to 30 V DC supply range, the sensor is compatible with standard industrial power systems and functions reliably across a temperature range of –25 °C to +55 °C.

Compact yet powerful, the WTB12-3P2441S59 can be installed in space-limited areas without compromising performance. Its combination of long-range through-beam detection, precise PinPoint LED alignment, rugged IP67 housing, and flexible output makes it a dependable solution for automation engineers seeking reliable, high-precision object detection.
