20-pin 1 mm pitch SMT header with latch holder
Molex 5011902017 is a 20-position, 1.00 mm pitch surface-mount header from the Pico-Clasp 501190 series. It uses a latch holder fastening type — the mating receptacle clicks in and stays put under vibration, which matters for cable-to-board connections in portable or moving assemblies. The contact base is phosphor bronze, a standard spring alloy for this pitch class.
