About the D38999/20WB35SN Circular Connector
D38999/20WB35SN is a circular connector receptacle qualified to MIL-DTL-38999 Series III, one of the most widely used interconnect standards on modern aerospace and defence platforms. The designation decodes as follows: ’20’ identifies a wall-mount receptacle; ‘W’ specifies an olive drab cadmium finish; ‘B’ is the shell size code, corresponding to shell size 11; ’35’ is the insert arrangement, providing 13 size 22D contact cavities; ‘S’ specifies socket (female) contacts; and ‘N’ indicates normal polarisation. Series III connectors use a triple-start threaded coupling, are scoop-proof, and are intended for severe-environment service across vibration, moisture and temperature extremes; distributor data lists an operating range of −65 °C to +200 °C for this part. Crimp contacts to the M39029 specification are used with D38999 connectors and are typically ordered separately.
