Right-angle 12-pin header for wire-to-board harnesses
The S12B-XH-A is a 12-position, single-row header from JST's XH series, designed for board-to-cable/wire applications. It uses a 2.50mm pitch and mounts through-hole at a right angle, routing the mating cable parallel to the PCB — a common choice for compact enclosures where vertical clearance is tight.
Board fit and mating compatibility
This header mates with JST XH series crimp receptacles (e.g., XHP-series housings with SXH-001T-P0.6 terminals). The 0.134" (3.40mm) post length suits standard 1.6mm PCBs; the right-angle orientation requires a board edge clearance of at least the insulation height of 0.240" (6.10mm).
