Wireline Collector Slip Rings

ROTOCON Wireline Slip Rings (MXV)

ROTOCON High-Performance Brushless Slip Ring Solutions

» Provides a maintenance-free, high-voltage (600V - 3500V) slip ring 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

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 are available in up to 12 conductors total. Custom ROTOCON wireline slip ring models can be configured up to 3500V and 20 conductors.

ROTOCON wireline collector rings are oil-filled and environmentally sealed – allowing them to operate outdoors and in harsh environments without any additional protective covers or measures necessary.  They are unaffected by dust and water and do not require any routine maintenance or adjustment – simply delivering an extremely clean signal without noise, shorts, or cross-talk; providing end-users with better data in the field resulting in higher yield with less downtime.

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 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.

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.
