SICK Retroreflective Photoelectric Sensor Block Style, Metal Housing, 2 m Detection Range, PNP Output WL12-3P2451

SICK WL12-3P2451 Retroreflective Photoelectric Sensor Block Style features a metal housing and operates within a 2-meter detection range. Suitable for industrial automation tasks, this sensor provides reliable object detection with its robust ingress protection ratings of IP66, IP67, and IP69K, ensuring performance in demanding production and washdown environments.

Designed for small-object sensing, it uses a visible red LED light source at 640nm wavelength, emitting a focused illumination pattern that supports precise detection. The sensor operates on a maximum DC voltage of 30 V with a current consumption limited to 30mA for efficient power usage. A fast response time of 330 microseconds supports high-speed operation for pick-and-place or conveyor systems.

The sensor includes essential electrical protections such as reverse polarity, interference suppression, and short-circuit protection to enhance longevity and safety. Sensitivity adjustment is possible using a five-turn potentiometer with visual LED indication for easy calibration.

Connectivity is ensured by a 4-pin M12 male connector configured for standard PNP wiring, compatible with 10 - 30 V DC supplies. The sensor shows a wide operating temperature range from -40°C up to 60°C, making it suitable for harsh work environments.

This durable component offers an expected Mean Time To Failure (MTTF) of 1,388 years and an LED lifespan of approximately 100,000 hours at 25°C continuous operation, confirming its reliability in continuous industrial applications.

Equipped with a PNP output type for simple interfacing with controllers. Robust metal housing rated IP66, IP67, and IP69K for harsh industrial environments. Fast response time of 330 microseconds enables high-speed detection.

Operates reliably from -40°C to +60°C temperature range. Utilizes a 640nm visible red LED light source with focused beam for detecting small parts. Includes reverse-polarity protection and output short-circuit protection.
