What the 6.35mm pitch and 12A rating mean for your board
The 600 VAC voltage rating is line-to-line for industrial power distribution. Three rows at 6.35mm row spacing give a 15-position layout that balances current density with board real estate.
Mating half and build-to-print BOM
This header mates with Universal MATE-N-LOK receptacle housings and crimp terminals. The build-to-print BOM needs the header body (641976-4), the matching receptacle housing, and the appropriate male pin terminals — all sold separately.
Temperature range and environmental fit
The white nylon housing resists moisture absorption better than standard PA66 grades.
