6.35 mm pitch, 2-position power header
The 641963-1 is a single-row, 2-position header from the Universal MATE-N-LOK series by TE Connectivity AMP Connectors. It uses a 0.250" (6.35 mm) pitch, which gives generous routing space on the PCB and matches the standard Universal MATE-N-LOK receptacle housing. Rated 12 A per contact at 600 VAC, this header is built for power distribution in general-purpose equipment — not just signal-level interconnect.
Shrouded 4-wall with locking ramp
Board guide features help align the header during automated placement, reducing skew on the pick-and-place line.
