Amphenol 9446F16-12P M85049 52-1-16N (183-3) Pin Plug Connector

Amphenol Matrix 9446F16-12P is a straight 12‑position pin plug from the Matrix 9446 family, engineered for rugged MIL-spec circular assemblies where reliable, multi-pin connections are required in harsh environments. The 12P insert denotes a twelve-contact pattern designed to mate with the corresponding receptacle in the same Matrix/9446 ecosystem, providing a compact, heavy‑duty plug for fielded equipment. This configuration is shown together with the M85049/52-1-16N (183-3) strain-relief backshell, a MIL-spec accessory that secures the cable and provides a robust interface between the connector and harness. The 9446 family emphasizes keyed mating interfaces and modularity, enabling interconnection schemes that can be tailored to specific installations. Availability of M85049/52‑series backshells from major distributors—Mouser, DigiKey, Newark, RS, and PEI-Genesis—across multiple regional catalogs confirms this backshell option is widely used in defense, aerospace, and industrial applications requiring MIL-spec support and standardized accessories.
