The 917251-3: Right-angle through-hole mounting with full 4-wall shrouding protects the tab contacts during handling and mating. The detent lock provides audible feedback on engagement and resists vibration-induced disconnect.
This header mates with a Dynamic D-3400 series receptacle housing that accepts the matching crimp tab terminals. The 4-row, 20-position layout and 0.150" pitch define the mating interface — confirm the receptacle part number against the series catalog.
