SICK Retroreflective Photoelectric Sensor, Rectangular, 2 m Detection Range, NPN Output, IP69K IP67 IP66 WL12-3N2451

The SICK WL12-3N2451 retroreflective photoelectric sensor is engineered for industrial automation environments requiring accurate detection of small objects. Its rectangular metal body combines durability with high ingress protection levels of IP69K, IP67, and IP66, making it suitable for washdown and dusty conditions.

Featuring an NPN output and a 4-pin M12 connector interface, the sensor integrates seamlessly with various control systems. It operates reliably across a broad temperature range from -40°C to 60°C, allowing deployment near heat sources or cold storage without additional thermal safeguards.

The sensor delivers a detection range of 2 meters using retroreflective LED light, optimized for diminutive parts on conveyor belts or packaging lines. Its rapid 330 microsecond response time supports high-speed operations, while a threaded mount ensures stable installation in machinery setups.

Common uses include presence detection of small components on conveyor systems, packaging line reflective sensing, and machine vision pre-trigger sensing in industrial automation. This sensor is well suited to environments demanding high protection against dust and moisture, including food processing or washdown areas.

The sensor uses retroreflective LED technology for precise detection of small objects. It features a metal housing with IP69K, IP67, and IP66 ingress protection ratings for harsh environments. The output type is NPN, compatible with common industrial control systems.

Equipped with a 4-pin M12 connector for straightforward wiring and installation. Operates within a wide temperature range from -40°C to 60°C for varied factory conditions. Supports a maximum DC voltage of 30V and current of 100mA for safe electrical integration.

Response time is 330 microseconds enabling rapid sensing for high-speed processes. Threaded rectangular mounting facilitates secure fixing on panels or brackets. Ideal for conveyor small part presence detection and packaging line applications.

This sensor is manufactured in Germany and belongs to the SICK W12-3 series, reflecting a high standard of quality and reliability. For further details and technical documentation, please refer to the official datasheet.
