The SICK FORK SENSORS WF15-40B410, WF5-40B410, WF15-40B416, and WF50-40B410 represent a family of high-performance fork sensors designed for precise optical detection in automation tasks. These sensors leverage an infrared LED (850 nm) light source and a fork-shaped housing to deliver reliable label detection and small-object sensing. With a fork width of 50 mm and depth of 42 mm, they are ideal for applications requiring consistent monitoring of transparent or opaque materials. Their robust aluminum construction and IP65 rating ensure durability in demanding settings, while the 10 kHz switching frequency and 100 µs response time enable high-speed counting and positioning. The sensors feature intuitive push-button adjustment for sensitivity and light/dark switching, along with PNP/NPN output options for seamless integration into control systems.
