Latest company news about Specific Parameters Of Fiber Optic Rotary Joint And Application Range

Fiber optic rotary joints:


Fiber optic rotary connector is also called optic slip ring and optic&electrical collector ring. It adopts fiber optic slip ring to transmit media for data and to solve data transmission between system parts. Especially it’s used in unrestricted, continuous or intermittent rotation. At the same time it transmits large volume data from fixed position to rotating position.


Application range of this series of slip ring:

1) Signal transmission between welding robots and control table


2) Signal transmission between remote mechanical input / output device and control system


3) The connection between control table and spacecraft tracking

4) Photo-electric theodolite

5) Material conveying system

6) Signal transmission between submarine robot and control ship

7) Signal transmission between radar antenna and on-board signal processing system

8) Signal transmission between the rotating turret and the inside console of a car body
