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 wireline applications, Meridian Laboratory offers numerous drop-in replacements for original equipment manufacturers or maintenance operations – click here for high voltage wireline slip rings.

The ROTOCON platform utilizes a sealed contact system that is brushless 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 noise from our rotary electrical union.
