ROTOCON MXO Harsh Environment

Capsule and Sealed Slip Rings for Oceanographic and Harsh Industrial Environments

Meridian Laboratory’s ROTOCON MXO Series slip rings are ideal for demanding applications in wet, humid, and harsh industrial environments.  By utilizing additional sealing technologies, the MXO Series is specifically designed to be unaffected by direct and indirect contact with water and other mediums (oils, detergents, and other chemicals).

Unlike conventional brushed slip rings which rely on metal on metal contacts and are limited by RPM, electrically noisy, and require adjustment and maintenance for proper operation, all ROTOCONs are brushless, functioning through a molecularly bonded viscous metal film which remains unaffected by speed, provides clean and noise-free electrical signals, and requires zero maintenance.

The MXO Series of capsule and sealed slip rings is offered with a variety of termination options, depending on ingress protection rating and preference.  Like all ROTOCON rotary electrical connectors, the MXO Series is brush-free and maintenance free, while providing better signal integrity and longevity than conventional brushed slip rings.
