12-position vertical header at 3.50 mm pitch
The 1-284516-2: This is a 12-position, single-level, vertical through-hole header from TE's Buchanan series, with a 0.138" (3.50 mm) pitch. The green colour is standard for the Buchanan terminal block family, helping visual identification on the board or in the cabinet.
At 11 A per circuit, this header carries the same current rating as the 12-position sibling 1-284514-2 and the 10-position 1-284517-0 (which uses a 0.150" pitch). Compared to the right-angle variant 1-284539-2 (same pitch, same 12 positions, same current), this vertical orientation lets the mating plug enter perpendicular to the PCB, which can simplify wire routing in a cabinet where the header sits on a backplane or I/O board.
