Fork Sensor – WFM30-40P321

The WFM30-40P321 fork sensor from the WFM series delivers fast and accurate object detection using a reliable optical detection principle. With a fork width of 30 mm and depth of 42 mm, it can detect objects as small as 0.8 mm, making it perfect for precise positioning, edge detection, or label sensing.

This sensor features a red LED light source, high switching frequency (4 kHz), and PNP switching output, ensuring rapid response and compatibility with modern control systems. Designed for industrial durability, the IP67 enclosure rating and robust circuit protection make it suitable for tough environments with dust or moisture exposure.
