Original Press Release:

Single-pin Connector Series from Amphenol Offers Higher Amperage, Lower T-rise

Sidney, N.Y. – Amphenol Industrial Global Operations, a global leader in interconnect systems, has introduced a single-pin, high amperage connector series that features Amphenol’s patented RADSOK technology.  Rig-Lok has a higher amperage rating and lower T-rise and insertion/removal forces as compared to any rugged connector on the market. 

This new connector series is used by oilfield equipment manufacturers, power generation OEMs, power distribution panel suppliers and traction motor OEMs. Unlike similar products with threaded connections, the new Rig-Lok is ideal for use in VFD drive buildings, land drilling, traction motors and top drive power distribution because of its secure mating mechanism. 

The connector features a unique 1/4 turn reverse bayonet locking coupling that allows for audible, tactile and visual confirmation of secure mating.  Its double-dead front, finger-proof inserts help to protect the pin, as well as the socket, and enables the user to offer standard and reverse service within the same connector package.

Available with a variety of alternate keyway options, Rig-Lok prevents the inter-mating of different circuits with the panels on which they are used.  The connector series is offered in two shell sizes, giving the user the ability to terminate wire sizes ranging from 4/0 AWG to 777 MCM cable, and has an amperage rating up to 1,135 A at 2,500 VDC.

Rig-Lok features rugged corrosion resistant plating with a hard coat anodized finish that is able to withstand 300 days of continuous salt spray.  The ruggedized, over-molded coupling nut supplied with each connector gives users more grip when operating in harsh environments, like oilfields where temperatures go down to -40ºC.  A machined aluminum cover comes standard with the RoHS-compliant connector series, providing more protection for insert and contact assembly.

Pricing for the Rig-Lok starts at $450 per set. Delivery is 6-8 weeks ARO.
