What this 4-position Pico-Clasp header does
The 5019530407: This is a 4-position, single-row header from the Pico-Clasp 501953 series, designed for board-to-cable/wire connections. The locking ramp on the shroud gives a positive retention against vibration or accidental pull — you should hear it click when the mating receptacle seats. The shrouded 4-wall design protects the pins and guides the mate.
