Profile: Alpha Slip Rings, Inc® is involved in the design and manufacture of tens of thousands of slip ring assemblies for all industries. Our products include fiber optic, two and multi-channel fiber optic, custom single-channel, wireline truck, high temperature, and electrical slip rings. We are specialized in designing and building slip rings for just about any application such as ROVs, perimeter surveillance radar systems, oil well logging tools, wind generators, industrial robots, centrifuges, packaging machines, pallet wrapper & liquid filler machines. We also modify several of our standard assemblies to incorporate fiber optic rotary joints. The fiber optic rotary joints and slip rings operate totally independent of each other. Our multi-pass fiber optic rotary joints connect 5-10 independent fiber channels simultaneously. They allow uninterrupted transmission of optical signals while rotating along the common mechanical axis. The RJn series FORJs feature unmatched crosstalk performance for singlemode fibers. Pressure compensation is also available with this model. All channels accommodate single-mode/multi-mode fibers. It is also possible to combine the two types of fibers in one device. Our SR723 series slip rings are designed to incorporate Princetel's MJn and RJ2 series FORJs. This integrated device is easily separated in the field for repair/maintenance. This rugged slip ring promises low maintenance and a very long life cycle. It is sealed from dust and occasional water splash & is suitable for airborne applications such as aerostats. 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.
