Board Fit and Pin Protection
The 10127820-0422LF: The locking ramp on each side gives an audible click when the receptacle seats fully—you should hear it lock. In a vibration environment, that ramp keeps the pair mated where an unshrouded header would let the connector walk apart.
The 10127820-0422LF mates with the Minitek® Pwr 4.2 receptacle housing (female crimp socket sold separately).
