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 M-Series, end of shaft slip ring alternatives are available in different capacities capable of providing power and signals up to 100 contacts, and up to 35A/contact.

Like all other ROTOCON rotating electrical contacts, the M-Series is designed to be able to accommodate signal/data level transmission (see full list below) as well as high current power transfer.  Similarly, the ROTOCON M-Series remains unaffected by machine vibration or rotational speed, throughout its entire RPM range. The ROTOCON M-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.

For power transmission, this means zero internal arcing and premature wear – allowing for increased reliability and longevity. ROTOCON rotary electrical connectors oftentimes outlast conventional brushed slip rings between 5 and 25x without the need for maintenance, adjustment, or downtime.

For signal transmission – this means ROTOCONs are guaranteed to transfer 100Mbps and 1Gbps Ethernet (or equivalent communication protocols) without the loss of packets, occurrence of bit errors, and other data problems that routinely occur with traditional, brushed slip rings.

The ROTOCON M-Series is designed for continuous use, industrial applications and is routinely used in a variety of packaging, test & measurement, food processing, strain & torque measurement, oceanographic instrumentation, and many other manufacturing & production related processes.

The ROTOCON platform utilizes a sealed contact system that is brushless, 100% maintenance-free, and provides the cleanest electrical signal available in any rotary electrical contact solution, for both power and data signals, you can count on no measurable change of resistance (noise) from a ROTOCON rotary electrical union.
