What the 30µin GXT Gold Buys the Design
It handles 500+ mating cycles before the contact resistance drifts, which matters if this connector sees quarterly reconnects in field-service gear or test fixtures. The post finish is 78.7µin tin — the solder tail wets to the board pad normally; no special flux or pre-tinning needed.
Shrouded on all four walls — the mating receptacle is guided into alignment before the pins engage, which prevents bent pins during blind-mate assembly. Keying slot and mounting flange — the flange takes a screw or rivet through the board for mechanical retention; the keying slot prevents mating with the wrong receptacle orientation.
Mating and Series Compatibility
Board-to-cable/wire style — mates with a Quickie™ series receptacle that accepts discrete wires or an IDC ribbon cable.
