209313 - Miller 209313 CST-100 II Socket Contact (26-22 AWG) - 5 Pack

Technical Overview of the Miller 209313 Connector Socket

The Miller 209313 is a specialized rectangular connector contact designed for use within the internal electrical systems of Miller welding equipment. Identified as a socket-style contact belonging to the CST-100 II series, this component is engineered to provide secure and reliable signal transmission between printed circuit boards (PCBs) and wire harnesses. The contact is specifically sized to accept wire gauges ranging from 26 AWG to 22 AWG, making it suitable for low-voltage control signals and sensor data transmission within the power source architecture.

Manufactured with a tin-plated finish, the 209313 contact offers excellent solderability (if required) and resistance to oxidation, ensuring low contact resistance over the lifespan of the machine. The tin plating is particularly effective in standard industrial environments where consistent electrical performance is paramount. As a crimp-style contact, it requires appropriate tooling to ensure a gas-tight connection between the wire strands and the terminal body, preventing signal loss or intermittent faults caused by vibration—a common stressor in industrial welding environments.

This product is supplied as a package of five, allowing technicians to perform multiple terminations or have spare contacts on hand during complex harness repairs. The CST-100 II series is widely utilized in various Miller equipment lines for its compact form factor and reliable locking mechanism when paired with the corresponding housing. Using genuine OEM contacts like the Miller 209313 ensures that the retention force within the connector housing meets factory specifications, preventing pins from backing out during operation. This attention to detail in component selection helps maintain the overall integrity and safety of the welding system.

For maintenance professionals and industrial electricians, sourcing the correct contact is critical for preserving the UL/CSA listings of the equipment and ensuring that control logic functions operate without error. The Miller 209313 provides the exact dimensional and material properties required for seamless integration into existing Miller wire assemblies.
