PJ2-FORJ Series

Two Channel Fiber Optical Rotary Joint

Plastic optical fibers (POF) possess a few important characteristics that make them favorite choices for certain short-distance fiber optic applications. Their large cores allow easy light coupling. Termination can be simplified to quick hot knife cutting or diamond turning. They are bend-insensitive and do not fatigue easily.

Our PJ2 series 2-channel FORJ connects two independent fiber channels simultaneously. They are blind-spot-free during rotation and are ideal for machine control applications such as SERCOS Interfaces. The rugged design permits underwater usage. Damaged fibers can be easily replaced without costly repairs of the FORJ itself.
