Product details

0.100-inch pitch, 6-position, friction-lock header

The housing is natural thermoplastic, rated UL94 V-0, and carries 6 positions with 5 contacts loaded. The unloaded position is a keying or polarization feature — confirm your harness pin count against the BOM.

Tin plating, solder termination, and temperature range

Both the mating and post contact finishes are tin.

The bulk package is standard for this part.

Peer comparison: 1-292164-1 and 953440-3

The 643494-4 offers a wider 0.100" pitch and a friction lock at 250 VAC — a different footprint and locking mechanism.
