1.50 mm pitch, 10-position right-angle header
The S10B-ZR is a 10-position, single-row header from JST's ZH series, on a 1.50 mm pitch — the tightest spacing in the ZH family, which means the board footprint stays compact for a 10-circuit wire-to-board interface.
1 A per contact, 50 V — signal-level duty
11-position sibling for one more circuit
If the BOM needs one more circuit, the S11B-ZR shares the same 1.50 mm pitch, right-angle through-hole footprint, tin plating, and detent lock — just with 11 positions instead of 10.
