The SICK WTF11-2P2431 (Part No. 1041380) is a high-performance retro-reflective photoelectric sensor designed for accurate object detection in industrial automation and material handling applications. Part of the WTF11 series, this sensor combines robust design, fast response, and reliable detection technology to ensure consistent performance in a wide variety of industrial environments.

At the core of the sensor’s functionality is a visible red LED light source that operates in conjunction with a reflector. This retro-reflective setup enables the sensor to detect objects when the emitted light beam is interrupted by a target. The design ensures reliable detection even in environments with variable backgrounds, as the sensor relies on the reflection of its own emitted light rather than background contrast.

The sensor offers a nominal sensing distance of 200 mm, with an adjustable range from 40 mm to 500 mm, allowing flexibility for different object sizes and detection distances. This wide adjustment capability makes the sensor adaptable to various setups, including conveyor monitoring, packaging verification, and part presence detection. Operators can fine-tune the detection range during installation to achieve optimal performance and reduce false signals.

Equipped with a PNP switching output, the WTF11-2P2431 delivers fast and accurate electrical signals for integration into PNP logic control systems. Its rapid response time ensures precise detection of moving objects, supporting high-speed automation processes with minimal error rates. The combination of retro-reflective sensing and fast PNP output makes it particularly suitable for applications requiring reliable object presence verification in dynamic industrial settings.

The sensor’s mechanical design emphasizes durability and compactness. It is housed in a rugged plastic enclosure rated IP67, providing protection against dust and temporary water exposure. This ensures reliable operation in harsh industrial environments and facilitates installation in confined spaces without sacrificing detection performance.

Electrical operation is supported by a 10–30 V DC supply, and the sensor includes reverse-polarity protection and short-circuit resistance, enhancing longevity and reducing maintenance requirements. Standard M12 connectors simplify wiring and integration into automation systems.

Applications for the WTF11-2P2431 include object detection on conveyors, packaging verification, part presence control, and automated assembly line monitoring. Its combination of retro-reflective sensing, adjustable range, high-speed PNP output, and rugged IP67 housing make it a dependable and versatile choice for modern industrial automation environments.

In summary, the SICK WTF11-2P2431 provides reliable retro-reflective detection with adjustable range, fast PNP switching, and durable IP67-rated housing, ensuring accurate and consistent performance across demanding industrial applications.
