About the D38999/20WB35PN Circular Connector
The D38999/20WB35PN is a circular connector qualified to MIL-DTL-38999 Series III, the workhorse high-density interconnect specification for military and aerospace electrical systems. Decoding the part number against the specification: /20 designates a wall-mount flange receptacle; W is the shell material and finish code for aluminium with olive-drab cadmium plating; B is shell size 11; insert arrangement 35 in this shell provides 13 contact cavities; P designates pin (male) crimp contacts; and N is the normal (master) polarisation key position. Series III connectors feature a triple-start threaded coupling and use rear-release M39029 crimp contacts, and the family is qualified for demanding shock, vibration and environmental exposure. This item is supplied as an Amphenol Aerospace manufactured connector; contacts for crimp variants are typically supplied with the connector and should be confirmed at quotation stage together with any sealing plug requirements.
