Amphenol 97-3102A-28-12P Circular Connector

Amphenol 97-3102A-28-12P is a box-mount, 97 Series circular receptacle connector with insert arrangement 28-12 and shell size 28. It uses 26 pin contacts (P) in a box-receptacle configuration and features a solid backshell for rugged panel installations; it mates with a corresponding plug, such as 97-3102A-28-12S, in normal orientation (N). As part of Amphenol Industrial Operations' MIL-spec circular interconnect lineup, this connector is designed for reliable electrical connections in environments where space is tight and vibration is common. The 97-3102A-28-12P is commonly used in aerospace, defense, and industrial equipment where a standardized, field-serviceable interconnect is required and where a box-receptacle provides a rear or panel-side termination while mating to a compatible plug. The insert arrangement 28-12 defines the distribution of contact positions across the assembly, enabling the routing of mixed signal and power circuits within a single connector. The shell size 28 and box-mount form factor support panel installation with fixed mounting holes and a rigid interface to the mating connector, ensuring alignment and consistent electrical contact through multiple mating cycles. This part number is one member of Amphenol’s 97 Series family, which is designed for high-reliability interconnections in demanding applications.
