The Amphenol 79821-112HLF is a 12-position, dual-row male header from the BERGSTIK II series, on the standard 0.100" (2.54mm) pitch grid. It is an unshrouded, through-hole solder-terminated board-to-board interconnect with push-pull fastening — no locking ramp, no polarization key. The square pins are phosphor bronze with a 30.0µin (0.76µm) gold or Gold GXT mating finish, rated for 5A per circuit at 110V. The black UL94 V-0 glass-filled polyester housing stands 0.100" (2.54mm) off the board, giving a low profile for tight card-stacking applications.
The 0.100" (2.54mm) pitch and 0.100" (2.54mm) row spacing place this header on the industry-standard DIP grid — the footprint matches any 0.100"-pitch receptacle or IDC socket. The unshrouded design means the header accepts any standard 0.100" receptacle, but offers no polarization protection against mis-mating.
