SR723 series sliprings are designed to incorporate Princetel's MJn series and
JXn series FORJs. This integrated device can be easily separated in the
field for repair or maintenance. The picture on the left shows a 6-ring version with a singlemode 3-channel (MJ3) FORJ.
Up to 40 rings can be accommodated in the design.
This rugged slip ring promises low maintenance and a very long life cycle (~30-100 million revolutions!). It is sealed
from dust and occasional water splash, suitable for airborne applications such as aerostats
(balloons or blimps).
All electrical wires and fiber cables are terminated with standard connectors.
A weatherproof utility box is attached to the rotor for convenient access to fiber connectors.
