The 1-332070-7: This is a Series 4 PCB pin socket from TE Connectivity AMP Connectors, designed to accept a pin diameter of 0.037" ~ 0.040" (0.94mm ~ 1.02mm) and terminate via solder into a plated through-hole. The contact is made from beryllium copper, a material chosen for its high fatigue strength and consistent spring force over repeated mating cycles — a practical choice for field-serviceable interconnects where the socket sees multiple insertions. The socket has no tail and a socket depth of 0.130" (3.30mm), meaning the pin is fully captured within the insulator bore — the solder joint at the mounting hole diameter of 0.072" (1.83mm) provides the mechanical retention.

What the knockout bottom feature means for your board
The knockout bottom allows the socket to be used in applications where the pin may protrude through the board — the bottom of the insulator can be removed to clear the pin tip, useful in tight z-height stacks or when the pin is longer than the socket depth.
