All 22 positions are loaded, so the pin layout is a straight 2x11 matrix with no skipped or keyed pins. Push-pull fastening, no locking latch.
That is a signal-level current — fine for logic-level power, I/O, or low-current board interconnects. This header is built for a one-time board-stacking or a low-cycle harness connection, not for frequent field reconnection. The 0.100" pitch and 0.100" row spacing set the board footprint — you need a 2x11 grid of 0.040" plated through-holes on that spacing. The mating pin length is 0.430" (10.92mm), the post length below the board is 0.200" (5.08mm), and the overall contact length is 0.730" (18.54mm). These dimensions matter for stack-height clearance in a mezzanine or parallel-board assembly. Housing is UL94 V-0 rated black thermoplastic. Through-hole termination — rework-friendly if a pin gets bent during assembly.
