Sick WF80-60B410 Fork Sensor
The Sick WF80-60B410 is an optical fork sensor designed for precise object detection in industrial automation. Its 80 mm fork width and 59 mm depth suit label or small-part sensing on conveyors. The sensor operates on 10 V DC to 30 V DC supply voltage with PNP and NPN switching outputs. It targets engineers integrating presence detection into packaging or assembly lines.
M8 Connector Installation and Setup
Connection uses a male M8 4-pin plug for straightforward wiring into standard sensor cables. Sensitivity and light/dark switching are adjusted via plus/minus buttons on the housing, with a key lock to prevent accidental changes. The aluminium housing meets IP65 enclosure rating for dust and water jet protection. Initialization takes 100 ms at power-up before the output becomes active.
Detection Capacity and Limits
The sensor detects objects down to 0.2 mm using an infrared LED light source at a 10 kHz switching frequency. Response time is 100 µs with ±20 µs stability and 40 µs jitter for consistent timing. Maximum output current is 100 mA per channel for driving PLC inputs or relays. Ambient light immunity reaches 10,000 lx sunlight, but detection range is fixed by the 80 mm fork geometry.

Questions about this item
How can I verify the sensor is detecting objects correctly after wiring it to a 10 V DC to 30 V DC supply?
The green LED indicates power and the yellow LED shows switching state; with a 0.2 mm minimum detectable object the yellow LED should toggle each time a label or opaque item passes through the 80 mm fork.
What comes in the box and what must I source separately for the M8 4-pin connector?
The sensor housing with integrated fork optics is supplied; an M8 4-pin female cable or field-attachable plug for the 10 V DC to 30 V DC supply and PNP/NPN output is not included.
Which fork width suits a 60 mm label web — the 80 mm version or a narrower model?
The 80 mm fork width and 59 mm depth accommodate webs up to 80 mm wide; if your web is 60 mm this version provides 10 mm clearance on each side for reliable edge detection.
