It's a board-to-board interconnect with a standard 0.100" (2.54 mm) pitch on both the mating interface and the row spacing — a classic footprint that matches decades of legacy layouts and common IDC receptacles. The contacts are phosphor bronze with a 100.0 µin (2.54 µm) tin finish on the mating end and tin on the solder posts, rated for 5 A per contact at 110 V. The housing is black UL94 V-0 rated thermoplastic, and the overall contact length is 1.040" (26.42 mm), with 0.820" (20.83 mm) of that on the mating side and a 0.120" (3.05 mm) solder tail for through-hole mounting.
The 0.100" pitch gives you a standard 2.54 mm grid, which means the footprint is compatible with a wide range of mating receptacles and prototyping boards.
It mates with any standard 0.100" pitch dual-row receptacle housing that accepts 0.025" square pins, such as the matching BERGSTIK II socket strip or a common IDC socket. Termination is through-hole solder, with the 0.120" (3.05 mm) post length suited for standard PCB thicknesses. All 54 positions are loaded — no option for selective population on this order code.
