V5FF-GR-420JC is a stainless steel high-temperature diffuse reflective fiber optic sensor head with mechanical protectection and with an M4 threaded body and 2-meter cable length, designed for compact mounting and reliable sensing of small objects in harsh automation environments. It is typically paired with a separate fiber amplifier.
 
Main features and functions:
Type: Diffuse reflective glass fiber sensor—detects objects by reflected light from the same emitter/receiver head, suitable for position and presence sensing.
Mechanical design: M4 screw-type stainless steel housing (SUS304), bend radius R25, cable length 1 m. Compact build fits tight industrial spaces.
Sensing performance: Minimum detected object diameter around 0.1 mm (gold wire), typical detection range 80–100 mm.
Temperature: Head rated for continuous use up to 350°C.
Applications: Ideal for capsule fill checks, small-part detection, and presence/absence verification in high-temperature zones on filling, assembly, and packaging lines.
