SICK WF120-95B416 Fork Sensor

SICK WF120-95B416 Fork Sensor (part no. 6028470) is a compact infrared fork sensor designed for fast part-detection in conveyors and assembly lines. The fork is 120 mm wide with a 95 mm depth, and the housing dimensions are listed as 10 x 150 x 110 mm, offering a slim profile for tight installations. It uses an infrared LED as the light source and provides adjustable light/dark switching via a plus/minus teach-in button, with a key-lock option for two-point teach-in. The unit operates on 10–30 V DC and draws up to about 100 mA, with a switching output configurable as either PNP or NPN, making it compatible with a wide range of control systems. It supports a maximum switching frequency of 10 kHz and a response time of ≤100 µs, enabling reliable detection at high speeds. Wiring is via a robust M8 4-pin connector, and the sensor can be configured for both light-on and dark-on operation to suit different detection scenarios. With an MTTFD of 97 years, the WF120-95B416 is aimed at demanding industrial environments requiring durable, precise fork-sensor performance.
