The SM07B-NSHSS-TB is a 7-position, single-row header from JST's NSH series, pitched at 0.039" (1.00 mm) and terminated in a right-angle SMT footprint. It carries a 1 A per contact current rating at 50 V, which puts it squarely in signal-level interconnect — think sensor inputs, control lines, or low-power data paths, not motor feeds or bus bars.
The 7-position variant fills the gap between those two, useful when a design needs an odd count that doesn't waste a position.
