Board-to-wire header with latch holder
The BM12B-NSHSS-TBT (LF)(SN) is the 12-position member of JST's NSH board-to-cable/wire header line, a single-row shrouded header with a latch holder for positive retention. Rated 1 A per contact at 50 V, the header uses tin-plated mating contacts and mounts via surface-mount solder termination. The 1.00 mm pitch and 7.8 mm mated stacking height suit dense board layouts.
Position count and footprint fit
The 12-position BM12B-NSHSS-TBT (LF)(SN) sits in the NSH series alongside other position counts at the same 1.00 mm pitch. The single-row layout and 7.8 mm mated stack height are common across the series — match the position count to the circuit count on the board.
Housing and temperature range
The header uses a polyamide (nylon) housing rated UL94 V-0 and operates from -25°C to 85°C. The shrouded 4-wall design with latch holder protects the contacts and locks the mating cable plug in place.
