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.
