Two Positions, 6.35 mm Pitch — What That Buys the Board Layout
The 1-641964-1: The locking ramp provides a vibration-resistant mate: the audible click confirms full engagement, preventing back-out in equipment with moderate shock or continuous operation.
This header mates with Universal MATE-N-LOK receptacle housings that accept the matching crimp terminals — the 4-wall shrouding guides alignment and prevents pin damage during blind mating.
Lifecycle and Sourcing Status
RoHS compliant per the current directive — no lead in the mating finish, though the solder tails carry tin-lead plating, so check your assembly's exemption status if full RoHS is required.
The 1-641970-1 is a 6-position, 3-row version of the same Universal MATE-N-LOK header — same 0.250" pitch, same 12 A rating, same locking ramp and shrouding.
