This is a through-hole solder termination part, push-pull fastening, with no shrouding or locking features — a straight, no-frills header meant to mate with a matching receptacle or IDC socket.
Where It Fits and What It Does
This header is designed for board-to-board signal interconnect, typically mating with a female socket or a ribbon cable IDC connector on the same 0.100" grid. The 36 positions on a single row give you a long, narrow footprint — about 3.6 inches of board edge — which is common for parallel bus headers, I/O breakout, or programming headers on industrial controllers. The 5A per contact rating at the 2.54mm pitch is enough for moderate signal loads and small relays, but the 110V voltage rating keeps it in the low-voltage control domain.
The 0.100" (2.54mm) pitch is the standard for legacy and hobbyist boards — any 0.1" grid perfboard or PCB footprint will accept this header. The 36 positions are fully loaded, so every pin is present; no keying or polarisation beyond the unshrouded pin arrangement. The 5A per contact is a per-circuit rating at ambient — derate if you're packing all 36 circuits at full current in a warm enclosure. The 110V rating is conservative for the 2.54mm pitch; creepage distance on a single row is adequate for that voltage. The overall contact length of 0.395" (10.03mm) breaks down as 0.200" mating length and 0.095" post length — the post is short, so it's meant for boards around 1.6mm thick or less. The UL94 V-0 housing means it's flame-rated for use inside equipment without extra fireproofing.
