Available. The Sick WL12-3P2431 is a photoelectric retro-reflective sensor from the W12 series, designed for precise object detection in industrial automation applications. Operating on the principle of autocollimation, it offers a sensing range up to 7 meters without the need for a reflector, enhancing installation flexibility. The sensor emits visible red light at a wavelength of 640 nm, with a light spot size of approximately 100 mm at a distance of 3 meters, ensuring reliable detection over extended ranges. Equipped with a potentiometer for sensitivity adjustment, it allows for fine-tuning to meet specific application requirements. The sensor features a PNP output with complementary switching, supporting both light-on and dark-on modes, and can handle output currents up to 100 mA, suitable for various control systems. Its robust housing, measuring 15.6 mm x 48.5 mm x 42 mm, is constructed from metal with a plastic front screen, providing durability in demanding environments. Designed to operate within a temperature range of -40°C to +60°C, it is rated for protection classes IP66, IP67, and IP69K, ensuring resilience against dust, water, and high-pressure cleaning processes. The WL12-3P2431 is an ideal solution for applications requiring reliable and precise object detection in challenging industrial settings.
