Board-to-wire header, 40 positions, shrouded
The B40B-PUDSS-1(LF)(SN) is the 40-position member of JST's PUD header series, a board-to-wire shrouded header with a latch holder for secure mating. Rated 3 A per contact at 250 V, the header uses tin-plated mating contacts and a through-hole solder termination. The 2.00 mm pitch and dual-row layout suit dense wiring harnesses where the mated stack height reaches 11 mm.
Pitch, stack height, and retention
The 2.00 mm pitch and 11 mm mated stack height set the board-to-wire clearance budget. The four-wall shrouding and latch holder keep the header aligned and locked under vibration — the board guide on the housing aids alignment during assembly.
