254008 - Miller 14-Pin Circular Connector Receptacle (Cable Mount)

Technical Precision with the Miller 254008 Connector

The Miller 254008 Connector is a specialized circular MS/Metal style component designed for the rigorous demands of welding signal transmission. This 14-pin receptacle is engineered for cable mounting, distinguishing it from panel-mount variations. It serves as the female end of a cable connection, typically used when constructing extension cables for remote controls or replacing the connector on specific wire feeder interconnect cables. Its robust construction ensures that sensitive control signals—such as potentiometer references and contactor closures—are transmitted without interference or interruption.

Specifications and Assembly

Technically, this connector features a 14-pin arrangement utilizing Size 20 contacts. The termination method is solder cup, which requires the installer to solder the wire leads directly to the connector pins. While this requires a steady hand and soldering equipment, it results in the most electrically sound connection possible, impervious to the oxidation and loosening that can plague mechanical connections over time. The connector includes a durable backshell assembly that provides strain relief, protecting the solder joints from tension when the cable is pulled or manipulated.

Compatibility and Use Cases

The 14-pin Amphenol-style standard is ubiquitous across the Miller Electric product line, found on TIG welders, MIG power sources, and multi-process machines. This specific part, the 254008, is critical for technicians and fabricators who need to maintain these systems. Common use cases include:

• Extension Cables: Creating a bridge between a machine and a remote foot pedal located 50+ feet away.
• Cable Repair: Replacing a crushed or severed connector on an expensive remote control cable, saving the cost of a full cable replacement.
• Custom Automation: Integrating third-party automation controllers that need to interface with the standard Miller 14-pin receptacle on the power source.

When dealing with industrial electronics, the quality of the connector shell and the plating on the contacts matters. Miller's OEM sourcing ensures that this connector meets the mating cycle durability and environmental resistance required for heavy industrial use. Ensure your serial number fitment is verified, or consult with our team to confirm this is the correct gender and style for your specific cable assembly project.
