New military and commercial applications are demanding a reduction in connector size and weight without a loss of performance. Amphenol NEXUS Technologies has met that demand with its new Miniature M55116-Type TAC Connectors for soldier-worn applications, radio systems, and ruggedized communications systems.

TAC Connectors are designed and manufactured to the exacting specifications of MIL-DTL-55116 requirements at half the size of the standard connectors.

Amphenol NEXUS Technologies TAC Connectors are the ideal choice to reduce size and weight and still maintain many of the same performance benefits wherever a M55116 connector is needed on a newly designed system.

  • Both plug and receptacle are 50% smaller than the standard M55116 connectors (M55116/4 and M55116/10, as a comparison)
  • Standard plugs have rigid contacts; jacks have spring-loaded contacts with solder cup terminals
  • Molded-in spring-loaded contacts provide self-cleaning feature and eliminate issues with pin/socket open contacts
  • Standard wire strain relief accommodates .125 and .250 cable diameter
