Board-to-Board or Cable Header with Board Lock
The 1-2040557-9: The detent lock fastening provides audible feedback on full mate, reducing the risk of partial engagement in production.
Current, Pitch, and Contact Plating
Rated 3A per contact at 125V, the tin-plated mating surface is suited for moderate-cycle applications — typically 50 to 100 mating cycles in industrial equipment. The 2.00mm pitch and 3.30mm row spacing allow dense board routing while maintaining clearance for the 12.44mm insulation height above the PCB.
