Product details

Board-edge header for a 2 mm harness interface

It's a shrouded, right-angle through-hole part with a locking ramp — built to mate securely with a PA-series crimp receptacle and stay mated under vibration. The tin-on-tin contact finish is fine for moderate mating cycles — the locking ramp is what keeps the connection tight on the line.

RoHS non-compliant per the listing — verify your assembly's exemption or waiver requirements before committing the line.
