1.00 mm pitch, 13 positions, right-angle SMT — the board-fit anchor
The SM13B-SRSS-TB: JST SH/SR series header, 13 circuits on 1.00 mm pitch — the 0.039" centreline matches the SR-series receptacle, so the board footprint is fixed once you pick the position count.
1 A per contact, tin-on-tin — signal-duty, not power
The tin-on-tin interface is fine for moderate mating cycles (tens to low hundreds) in indoor, non-corrosive environments. Operating temperature from -25°C to 85°C covers most consumer, commercial, and light industrial enclosures. Compared to the 12-position sibling (SM12B-SRSS-TB), this 13-position variant adds one circuit at the same pitch and current — the board layout just extends the pattern by one position.
