High Voltage Slip Ring Alternatives (>600V)

ROTOCON MXV Series

Slip Rings for High Voltage Applications

Meridian Laboratory’s High Voltage MXV slip rings are the perfect choice for applications operating greater than 600V, with standard and custom models available up to 5000V.  The ROTOCON MXV series is commonly used in wireline logging, mining cranes, etching machines, x-ray, ultra-sonic welding, cable reels, and downhole applications.  All MXV series slip rings feature the same inherent low contact resistance and zero-maintenance characteristics, inclusive to all Meridian Laboratory’s ROTOCON slip rings.  Meridian Laboratory’s MXV high voltage slip ring series can accommodate Ethernet, and all other low voltage, signal and control circuits in one solution.

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. Upgrading ordinary brushed slip rings to ROTOCON rotary electrical connectors will provide better signal integrity, zero maintenance, and eliminate the need for replacing or adjusting slip ring brushes.  Contact Meridian Laboratory for a quote today.
