FU-35FZ Keyence Fiber Optic Sensor Head – High-Flexibility Retro-reflective Sensing
The FU-35FZ is a high-performance retro-reflective fiber optic sensor head from Keyence, specifically designed for stable detection of transparent, shiny, or opaque targets. As part of the ToughFlex series, this unit features a specialized core that allows for extreme flexibility without compromising light intensity. By utilizing a retro-reflective method with a dedicated reflector, the FU-35FZ provides a reliable sensing solution for applications where target color or surface finish varies.
Extreme Bend Radius for Tight Installations
The standout feature of the FU-35FZ is its incredible R2 mm minimum bend radius. This allows the fiber to be routed through tight machine joints, cable carriers, and compact spaces that would break or degrade standard fiber units. Its integrated transmitter and receiver design (coaxial) simplifies mounting, as the sensor head only needs to be installed on one side of the detection path, aiming at a reflector.
