Product details

Pitch, position count, and what mates with it

The 1-640454-2: The single-wall shroud guides the mating housing from three sides; the open side means the header is not fully keyed against a 180° mis-mate, so orient the housing correctly before seating. Tin-on-tin contact interface (mating and post) keeps cost low for moderate mating-cycle applications; for repeated connect/disconnect cycles, the tin plating wears faster than gold, but for a one-time harness assembly it is adequate.

Sourced per RFQ; confirm BOM quantity and lead time at time of order.
