FAQ

To achieve the maximum sensing distance, it is recommended to use a Keyence amplifier from the FS-N series (e.g., FS-V31) or a similar high-power model that supports MEGA mode.

Yes, the fiber cable is free-cut. A dedicated fiber cutter, like the Keyence OP-87447, should be used to ensure a clean, perpendicular cut for optimal light transmission.

The minimum detectable object size is dependent on the amplifier used and the sensing distance, but it is typically rated for objects as small as 0.005 mm in diameter under optimal conditions.
