Stamped Socket for AMPLIMITE HDP-20 D-Sub Connectors
This is the socket half of the mating pair — it terminates to the wire and inserts into the rear of the receptacle connector body.
At this thickness, the gold layer provides a low-resistance, oxidation-free interface through repeated mating cycles — typically rated for 200 to 500 cycles in the AMPLIMITE HDP-20 series, depending on the housing and environmental seal. The gold also prevents fretting corrosion in applications where vibration is present, such as near motors or in mobile equipment. For a single-mate, permanent-install harness, a tin-plated contact would suffice; the gold here signals the designer expects the connector to be field-serviced or the equipment to live in a mildly corrosive atmosphere.
Termination and Assembly
The stamped construction means the contact is formed from sheet stock, giving it a consistent cross-section and predictable insertion force. The phosphor bronze spring temper holds the retention lance engaged in the housing cavity, so the contact stays seated when the mating pin is withdrawn.
