Light beam coupling in the stool core diameter, cross section processing is simple, not easy to be broken is a special performance, so the plastic optical fiber, plastic optical fiber has become a popular choice for short distance communications. The PJ2 type plastic optical fiber rotary joint provides two independent fiber channels simultaneously. There is no blind spot in the rotation process. It is the ideal choice in the mechanical control system. The structural design of PJ2 allows it to work underwater. Damaged plastic optical fibers are easy to repair without replacing expensive PJ2..
Optical fiber rotary joint, also known as optical fiber slip ring and optoelectronic shunt ring, uses optical fiber as data transmission medium, providing the best technical solution for data transmission between rotating connection system components. It is especially suitable for applications that require unrestricted, continuous or intermittent rotation, and also need to transfer large capacity data from fixed position to rotary position.
