The Sick WLD4FP-1H162130A00 Retro-reflective Sensor is built using a dual lens system that ensures optimal object detection with a minimal distance to the reflector. Offering a robust sensing range up to 4.5 meters, this sensor leverages a powerful PinPoint LED light source that emits visible red light at a 635 nm wavelength. The compact light spot size of Ø 38 mm at 1,000 mm enables precise detection even for small and narrow objects. Powered by a stable 10 V DC to 30 V DC supply voltage and supporting Push-pull PNP/NPN outputs, it delivers quick and flexible signal switching for various automation setups.
Designed with efficiency in mind, the WLD4FP-1H162130A00 offers a response time of less than 500 µs and operates at a high switching frequency of 1,000 Hz. It features a durable Plastic VISTAL® housing and a Plastic PMMA front screen, providing an impressive IP66 and IP67 enclosure rating for outstanding resistance to dust, moisture, and harsh environments. The compact rectangular flat housing measures just 16 mm x 40.1 mm x 12.1 mm and comes with a ready-to-connect 4-wire, 2-meter cable to simplify integration into tight spaces.
