ROTOCON High-Performance Brushless Slip Ring Solutions

» Provides a maintenance-free, compact, high-speed (2K - 10K RPM) solution » 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

For applications featuring a limited mounting space and/or operating at speeds above 2,000 RPM, Meridian Laboratory offers its unique compact ROTOCON MM Series.  With up to 12 contacts/channels available, the ROTOCON MM series of high-speed slip rings are capable of transmitting both low current power, as well as signal and data within the same assembly.

Like all ROTOCON brushless slip rings, the contact resistance is extremely low (<0.1mΩ), both when stationary and while rotating. The MM Series of high-speed slip rings is especially well utilized in high-speed applications (above 2,000 RPM) and remains unaffected in performance or longevity.

If you require more contacts than 12, or if the application is not space limited, see our full lineup of M-Series, End-of-Shaft, ROTOCON rotary electrical connectors. For applications that require operating speeds greater than 10,000 RPM (up to 40,000 RPM), see our UHS-Series, ROTOCON Ultra-High-Speed Rotary Transmitters.

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 ROTOCON slip rings 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 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.
