The 641972-3: It mates with the corresponding Universal MATE-N-LOK receptacle housing and crimp contacts to form a complete wire-to-board interconnect. Rated 12 A per contact at 600 VAC, the 0.250" (6.35 mm) square pitch grid — both mating and row spacing — provides ample clearance for power circuits and simplifies PCB routing for a 3-row layout.
The mating pitch is 0.250" (6.35 mm) with the same 0.250" row spacing, forming a 3-row, 9-position square grid. The header is fully loaded (all positions populated).
