Product details

The B40B-PUDSS-1: This JST PUD series header carries 40 positions in a dual-row layout with a 0.079" (2.00mm) mating pitch and the same row spacing, matching the footprint of the corresponding PUD receptacle. The through-hole solder tails extend 0.122" (3.10mm) below the insulator, suitable for standard PCB thickness.

Shrouded 4-wall with latch holder — vibration-proof mate

A board guide on the insulator helps align the connector pair during blind mating, reducing pin damage in assembly.

The mated stack height is 11 mm — confirm this matches the clearance between your board and the mating receptacle.
