The WF5-40B416 Sick Fork Sensor is engineered for precise detection of small objects in industrial automation environments. This WF5-40B416 Sick Fork Sensor integrates 5 mm fork width, 42 mm fork depth, 0.2 mm minimum detectable object, and PNP/NPN switching output for stable signal control. It belongs to the WFE series and operates using an optical detection principle with selectable light/dark switching.
In packaging machinery, conveyor tracking, and component handling systems, the narrow fork design supports accurate positioning and object verification. The 40 µs jitter ensures fast response, while IP65 protection and integrated circuit safeguards help maintain reliable performance under industrial operating conditions.
The WF5-40B416 connects through an M8 4-pin interface and supports up to 100 mA output current for PLC integration. With aluminum housing and 20 mA current consumption, this Sick Fork Sensor delivers consistent detection suitable for continuous industrial operation.
