SR221 series sliprings are designed to incorporate Princetel's MJn series or 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 shipboard environment and military applications. Pressure compensation for underwater application is available with this model. Larger current rating is possible for special applications. Please call for your special need.
