The 69958-104LF: This 8-position, 0.100" (2.54mm) pitch header defines a compact two-row footprint on the board. Mates with any LATCH-N-LOK™ receptacle housing that carries 8 circuits and a 0.100" pitch; the latch holder on this header locks into the matching ramp on the receptacle side for a vibration-resistant connection.
A ground pin is included in the header — this pin connects to the board ground plane and provides a low-impedance path for shield currents from the cable, reducing EMI coupling into the signal circuits.
