It is a board-to-board interconnect component, typically used to connect two PCBs in a parallel or perpendicular stack. Key specs: 5 A current rating per contact, 110 V voltage rating, tin-plated mating surface (100.0 µin / 2.54 µm thickness), and a right-angle through-hole termination. The phosphor bronze contacts are unshrouded with a push-pull fastening system. The black UL 94 V-0 rated housing handles the standard operating temperature range for commercial and industrial board-level interconnects.
The 0.305" (7.75 mm) post length gives enough through-hole depth for standard 1.6 mm PCBs. The 110 V rating is adequate for logic-level and low-voltage power distribution inside an enclosure.
