The WF5-40B41CA00 Sick Fork Sensor is designed for accurate small-object detection in industrial automation systems. This WF5-40B41CA00 Sick Fork Sensor integrates 5 mm fork width, 42 mm fork depth, 0.2 mm minimum detectable object, and push-pull PNP/NPN output to support reliable signal processing. It operates on an optical detection principle with selectable light/dark switching and belongs to the WFE series.
In conveyor lines, packaging machines, and assembly applications, the compact fork geometry ensures stable positioning and repeatable detection. The teach-in button and dynamic teach-in options allow sensitivity adjustment, while 40 µs jitter enables fast switching for high-speed operations.
The WF5-40B41CA00 connects through an M8 4-pin interface and supports up to 100 mA output current for PLC integration. With IP65 protection, aluminum housing, and integrated circuit safeguards, this Sick Fork Sensor maintains consistent performance in industrial environments.
