SICK Retroreflective Photoelectric Sensor Rectangular 7 m Detection Range PNP IP66 IP67 IP69K Metal Housing WL12-3P2431

The SICK WL12-3P2431 Retroreflective Photoelectric Sensor is an advanced rectangular-form sensor designed for precise object detection in demanding industrial environments. With a detection range reaching up to 7 meters, it utilizes a visible red LED as its light source, enabling reliable sensing using an appropriate reflector. Its robust metal housing is rated IP66, IP67, and IP69K for high protection against dust, water, and high-pressure washdowns, making it ideal for installations requiring durability and resistance to environmental stress.

This sensor features a PNP complementary output, simplifying interfacing with modern PLC and control systems. The compact rectangular design supports panel mounting and integration in limited-space assemblies. Electrical input ranges from 10 to 30 V DC, with a maximum current draw of 100 mA. Installation and maintenance are facilitated by a 4-pin M12 terminal and clear LED indicators: a green LED for supply and a yellow LED for received signal, enhancing onsite status visibility.

The WL12-3P2431 delivers a rapid response time of 330 μs, addressing high-speed automation needs. Sensitivity is finely adjustable via a five-turn potentiometer, allowing adaptation to varying reflector types and distances. Built-in electrical protections include reverse polarity, overcurrent, and short-circuit safeguards for safe operation. The autocollimation detection principle ensures accurate and stable performance in conveyor object sensing, machine safety presence applications, and packaging line automation, even amidst industrial noise and harsh conditions.

Operating temperature spans from -40°C to +60°C, catering to diverse climate scenarios. The LED offers an average life of 100,000 hours, minimizing maintenance. Typical applications include panel-mounted sensing in compact assemblies, high-pressure washdown areas, and machine safety zones. The sensor is compatible with standard reflectors, typically achieving 5 meters of reach, with optimal setups extending to 7 meters.

For correct operation a suitable reflector is required; various reflector models are recommended depending on installation specifics. The device’s approvals cover a broad range of industrial and international standards for safe and compliant use. The SICK WL12-3P2431 represents a high-performance, industrial-grade sensor solution for automated object detection and presence sensing.
