ROTOCON High-Performance Brushless Slip Ring Solutions

» Provides brush-free design requiring no user maintenance» Delivers clean electrical signal for both power & data, with no measurable noise
» Robust industrial design provides reliable long lasting performance » Remains unaffected by machine vibration or rotational speed

Meridian Laboratory’s MXT Through-Hole Series is designed for applications which require mounting on solid or hollow shafts. Offered in a wide variety of sizes up to 4.00” diameter, the shaft can be utilized as a drive shaft for the rotary portions of a machine, or for hydraulic or pneumatic lines through the center of the unit. Meridian Laboratory also offers fully integrated solutions with rotating unions and other add-ons.

Like all other ROTOCON rotating electrical contacts, the MXT through-hole slip ring series is designed to accommodate signal/data level transmission, (see full list below) as well as high current power transfer.  Similarly, the ROTOCON MXT through-hole series remains unaffected by machine vibration or rotational speed, throughout its entire RPM range.   The ROTOCON MXT through-hole series is offered in a variety of electrical termination options including ring terminals, flying leads, MIL-spec, or wet-mate connectors on both rotating and stationary ends.

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 ROTOCON MXT through-hole slip ring series is designed for continuous use industrial applications and is routinely used in a variety of industries including: packaging, test and measurement, food processing, strain and torque measurement, oceanographic instrumentation, and others.
