End-of-Shaft Slip Rings up to 100 Channels
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. For higher amperage, multi-channel applications see our complete line of High Current, MXP Series.
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.
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. For size constricted applications, see our full line of Miniature, MM-Series rotary electrical connectors.
