200087 - Miller 14-18 GA Push-In Circular MS Pin

Miller 200087 Circular MS Connector Pin Overview

The Miller 200087 is a specialized connector pin designed for use in Circular MS (Military Standard) connectors, commonly found in high-performance industrial equipment and welding machinery. This component is engineered to facilitate secure electrical connections for control signals and low-voltage power transmission. As a genuine Miller Electric replacement part, it guarantees compatibility with specific Miller equipment harnesses and plug assemblies, ensuring that maintenance and repair operations restore the machine to its original factory specifications.

Technically, this pin is rated for wire gauges ranging from 14 to 18 AWG (American Wire Gauge). This versatility allows it to be used in various circuits where medium-thickness wiring is required for durability and current carrying capacity. The pin is specifically designed to accommodate wire insulation diameters between 0.079 inches and 0.100 inches. This specification is critical for maintaining the environmental seal and mechanical stability of the wire within the connector housing. Proper insulation fitment prevents moisture ingress and reduces strain on the electrical crimp or contact point.

The "Push-in" designation refers to the assembly method within the connector block. These pins are typically inserted into the rear of a connector shell until they lock into place, often using a retention clip or barb mechanism integral to the pin or the housing. This design allows for efficient assembly and, when necessary, extraction using the appropriate tools. The use of MS-style connectors implies a high standard of durability, vibration resistance, and reliability, making this pin an essential component for maintaining the integrity of welding automation, remote controls, and wire feeder connections.

Industrial maintenance teams and procurement specialists should verify the specific connector series and wire requirements before ordering. The Miller 200087 provides a robust solution for extending the service life of expensive control cables and interconnects. By using OEM contact pins, operators avoid the risks associated with poor conductivity, intermittent signals, and connector damage often caused by ill-fitting aftermarket alternatives.
