Board-fit and mating half for the SM11B-SRSS-TB
The 1 A per-contact rating at 50 V suits signal-level interconnects inside consumer electronics, sensors, and compact control boards.
Sourcing and compliance reality
Position count contrast with the 12-position sibling
The SM12B-SRSS-TB shares the same 1.00 mm pitch, right-angle SMT orientation, shrouding, and 1 A rating — the only parametric difference is 12 positions vs 11. If your BOM calls for an extra signal line, the 12-position version drops into the same footprint length plus one pitch increment.
