In a tight enclosure, that 6.99mm rules out shallow headers. Closed-bottom construction means the socket base is sealed — no solder wicking up into the contact zone during wave or hand-solder termination. ## Beryllium Copper + 30µin Gold – Contact Endurance Beryllium Copper contact material gives the beam its spring memory — after hundreds of mate cycles the normal force stays above the fretting threshold. Tin-brass alternatives lose grip faster. In a field-service connector that sees quarterly cycling, that gold layer carries the connector past a decade of reconnects without exposing the base metal.","metaTitle":"TE 50871-4 Socket – 0.275\" Depth, BeCu Gold Contact","metaDescription":"TE Connectivity AMP 50871-4 Series 5 socket – Beryllium Copper contact, 30µin gold, accepts 0.042\"–0.049\" pin.
