Wireline Slip Ring MXV Models

A Cleaner Signal and Longer Lasting – ROTOCON Wireline Slip Rings

Meridian Laboratory offers a full line of ROTOCON MXV slip rings, collector rings, and rotary electrical connectors as drop in replacements to existing wireline logging reels and applications.  Standard wireline slip ring models are offered in voltages of 600V, 1500V, and 2500V and available up to 12 conductors total.  Custom ROTOCON wireline slip ring models can be configured up to 3,500V and 20 conductors.

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.


Customers rely on ROTOCON slip rings for their wireline success:

Meridian Laboratory MXV style slip rings have been superior to any other high voltage wireline slip rings we have tried in years past for our wireline trucks.  The sealed contact design of their slip rings keeps dust and debris from affecting the performance of the wireline slip ring.  We continue to replace all of our brushed slip rings from other manufacturers with Meridian Laboratory high voltage, MXV series slip rings as they wear out.  We highly recommend Meridian Laboratory MXV series slip rings for all wireline applications and oil field service providers.
