M28840 Shipboard Connectors

Amphenol PCD M28840 Shipboard Connectors meet MIL-DTL-28840 standards, are precision-machined, and meet superior mechanical shock performance. These connectors offer six keying options for both plugs and receptacles and are available in nine sizes: 11, 13, 15, 17, 19, 23, 25, 29, and 33. Amphenol PCD M28840 connectors are highly reliable, high-density connectors designed and tested to withstand extreme environmental conditions and demanding applications. These connectors are fully intermateable and interchangeable with any qualified M28840 connector and feature a backshell design for strain relief, EMI, and environmental sealing.
