FAQ

What type of amplifier is compatible with the FU-32 fiber unit?

The Keyence FU-32 is compatible with a wide range of Keyence fiber optic amplifiers, such as those in the FS-N series. Always check the amplifier’s manual to ensure compatibility, especially regarding the connection type.

Can the fiber cable of the FU-32 be shortened?

Yes, the FU-32 comes with a 2-meter free-cut cable. It can be trimmed to the desired length using a dedicated fiber cutter to ensure a clean, perpendicular cut for optimal light transmission. A poor cut can significantly reduce sensing performance.

What does the ‘unbreakable fiber’ with an R2mm bending radius mean for installation?

The ‘unbreakable fiber’ designation and a tight R2mm bending radius mean the fiber is highly durable and can be bent into a tight corner without breaking or significantly losing signal strength. This makes it ideal for routing through complex machinery or in applications with very limited installation space where standard fibers might fail.
