18-position dual-row receptacle on the 0.100" grid
The 5-534206-9: It mates with a matching 0.100" square-pin header — the classic AMPMODU grid that has been a workhorse for board-to-board and cable-to-board interconnects for decades. Rated 2 A per contact, this receptacle is a signal-level interconnect — the 0.100" pitch and phosphor bronze contacts with 30 µinch gold on the mating face keep contact resistance stable through repeated mating cycles.
In high-vibration environments, a header with a locking ramp or a secondary TPA is preferred, but for bench-top, test, and low-shock applications the push-pull interface is sufficient and simplifies unmating.
