Product details

4.5mm stack height for tight mezzanine spacing

The 40P-JMDSS-G-1-TF(LF)(SN): This JST JMD plug sets the board-to-board gap at 4.5mm mated height — a common dimension for compact handheld or portable device stacks where every millimeter of z-height is budgeted. The 0.50mm pitch and 40 positions in two rows keep the footprint small, but the 4.5mm stack means the mating receptacle's tail length and the opposite board's component clearance need checking before layout lock.

Gold contacts and solder retention for reliable assembly

Gold contact finish on all 40 circuits gives this plug a robust mating cycle life — the gold-on-gold interface resists fretting corrosion better than tin in low-voltage signal paths.

How it differs from the right-angle JMD sibling

The 40PS-JMDSS-G-1-TF(LF)(SN) is the same 40-position, 0.50mm pitch JMD plug but with a right-angle mount and a 4.80mm mated stack height — 0.30mm taller than this vertical version. If your board edge or enclosure forces a parallel-to-PCB orientation, the right-angle version fits; for a straight mezzanine stack, this vertical plug is the correct half.
