Pin Diameter and Contact Fit
The 5050462-2: This PCB pin socket accepts a pin diameter range of 0.014" to 0.026" (0.36mm to 0.66mm), which covers common component leads and test pins. The beryllium copper contact material provides the spring force needed to maintain consistent normal force across that diameter spread, so a 0.014" pin seats as securely as a 0.026" one without permanent deformation. The socket depth is 0.165" (4.19mm) with an overall length of 0.178" (4.52mm) — the pin insertion depth is just under the overall length, so the pin tip stops short of the solder tail end. That matters when stacking multiple sockets on a board: the pin protrusion below the socket is minimal, keeping the z-height predictable.
At 30µin, the gold layer is thick enough to survive several hundred mating cycles without exposing the underlying nickel or copper — in a test-equipment or programming fixture where the socket is cycled weekly, that translates to years of reliable contact before fretting corrosion becomes a concern. The open-bottom feature means the socket body has no closed end — the solder tail exits through the bottom, which also allows the pin to pass through if it's longer than the socket depth. This is common in press-fit or through-hole applications where the pin tip needs to extend past the socket for a secondary connection or visual inspection.
