2.00mm pitch, 22 positions — board-to-board signal routing
The 57202-G52-11ALF: This is a 22-position, dual-row unshrouded header from the Minitek® 2.00mm series, built for board-to-board stacking. The 2.00mm pitch and 0.079" row spacing set the PCB footprint — a tight enough pitch to save board area while still allowing easy routing for signal traces. Rated 2A per contact at 200V AC/DC, with a 0.157" mating pin length that gives a solid wipe before the push-pull interface seats.
Surface-mount termination, unshrouded push-pull
Push-pull fastening keeps insertion force low; there is no latch to align, which speeds up manual assembly but means the joint relies on the solder pads for mechanical retention against cable strain.
