The Amphenol BERGSTIK II 86840-436HLF is a 36-position, dual-row, unshrouded male pin header on the standard 0.100" (2.54mm) pitch. The tin-plated phosphor bronze contacts are rated 5 A per circuit at 110 V, with the full 100.0 µin (2.54 µm) tin thickness on the mating surface giving a solid number of insertion cycles for production or field-service reconnects.
The 0.100" pitch and dual-row layout are the footprint anchor — this header mates with any standard 0.100" pitch, dual-row receptacle that accepts 0.025" square pins. The 36 positions are loaded fully, so the BOM line count is the circuit count. The right-angle mount means the pin tails extend 0.230" (5.84mm) below the board surface — check your board thickness and clearance to the next board or chassis. The unshrouded design gives you access for probing or manual wiring, but the pins are exposed and can bend if the mating receptacle is misaligned during assembly.
The base product number 86840 covers the family; the -436HLF suffix encodes the 36-position, dual-row, right-angle, tin-plated variant.
