Description
The KEYENCE FU-A40 Fiber Unit (Thrubeam Type) is a high-performance fiber optic sensor head designed for non-contact object detection in industrial automation. This thrubeam (opposed) type fiber unit features an array beam design with a beam range of 40 x 0.25 mm, requiring connection to compatible KEYENCE amplifiers (such as the FS-N series) to achieve long-distance, high-precision detection. Constructed with a rugged zinc die-cast housing and a PBT sensing face, it boasts an IP67 protection rating for reliable operation in harsh industrial environments from -20°C to +50°C. The unit comes with a 2-meter freely trimmable fiber cable, offering flexible installation for automated production lines, material detection, and position monitoring applications.
