The SICK WTB11-2P2431 (Part No. 1041376) is a photoelectric proximity sensor designed to provide reliable object detection with integrated background suppression. As part of SICK’s WT11 family, it balances high performance, compact construction, and adaptability, making it an excellent choice for a wide range of industrial automation tasks.

At its core, the sensor employs a visible red LED emitter combined with background suppression technology. This ensures that objects are detected based on their position rather than on their reflective properties, preventing errors caused by shiny or highly reflective backgrounds. This feature is particularly valuable in packaging, conveyor systems, and assembly applications where accuracy and consistency are critical.

The WTB11-2P2431 offers a nominal sensing distance of 200 mm, with a configurable detection range between 40 mm and 500 mm. This flexibility allows operators to tailor the sensor to specific requirements, whether for short-range object detection or longer-distance applications. The adjustment is intuitive, supporting quick installation and commissioning.

Performance is reinforced by a PNP switching output, enabling direct integration into modern control systems. The sensor is engineered for fast response times, ensuring reliable detection even in high-speed processes. Combined with its precise background suppression, it minimizes false triggers and supports consistent operation across variable production conditions.

From a mechanical standpoint, the WTB11-2P2431 is designed for durability and compact integration. It is housed in a rugged plastic enclosure with an IP67 protection rating, which shields it from dust and water ingress. This robust design allows it to operate reliably even in harsh industrial environments. Its compact form factor also makes it easy to install in tight spaces without compromising detection performance.

Electrical specifications include an operating voltage range of 10 to 30 V DC, low current consumption, and protective features such as reverse-polarity protection and short-circuit resistance. These safeguards enhance long-term reliability and reduce the risk of downtime due to electrical issues. The sensor connects via standard M12 industrial connectors, simplifying wiring and integration into existing systems.

Measuring small yet powerful, the WTB11-2P2431 is a versatile sensor that excels in environments where space is limited but detection performance must remain uncompromised. Its ability to reliably detect a wide variety of targets, combined with rugged construction and straightforward configuration, makes it a dependable solution for machine builders, system integrators, and end users alike.

In summary, the SICK WTB11-2P2431 provides accurate, fast, and adaptable object detection in a compact, durable package. With background suppression, flexible sensing range, high-speed PNP output, and IP67 protection, it stands out as a reliable choice for modern automation systems that demand both precision and resilience.
