50-Pin, 2.54mm Pitch, Latch-Locked Header for AMP-Latch Ribbon Cable
The 1-5499922-0: This is a 50-position, 0.100" (2.54mm) pitch shrouded header from the AMP-Latch series — the standard IDC interface for ribbon cable to a PCB. The four-wall shroud and latch lock/eject hooks are what keep the mating socket from creeping off under vibration or cable strain.
