Product details

18-Position Shrouded Header with Detent Lock

The 280509-1: The shrouded 3-wall design and integral detent lock provide positive mating alignment and vibration resistance — the lock clicks home when the receptacle is fully seated, preventing accidental disconnection in equipment that sees shock or cable tug. The 0.260" (6.60 mm) mating pin length gives good wipe depth for reliable contact with standard AMPMODU receptacles.

Sourced through independent distribution — quoted to order against your BOM quantity; availability and current pricing confirmed at quote time.

This header mates with AMPMODU Mod II receptacles and female socket housings that accept 0.025" square posts on 0.100" centers. The detent lock engages with the matching ramp on the receptacle — confirm the receptacle part number includes the lock feature. Termination is solder to the PCB; the through-hole tails are tin-plated (118.1 µin) for good solder wetting.
