The S11B-ZR-SM4A-TF(LF)(SN): This is an 11-position single-row header on 1.50 mm pitch, surface-mount right-angle orientation. Solder retention pads on the SMT feet anchor the header during reflow and resist shear force from cable strain.
Mating Half and Locking — Build-to-Print Checklist
This header mates with JST ZH series crimp receptacles (female housings with crimp terminals). Build-to-print needs both halves: the receptacle and its crimp terminals are sold separately.
Peer Comparison — 11 vs 12 Positions
The closest sibling in the ZH series is the 12-position S12B-ZR-SM4A-TF(LF)(SN) — same pitch, current rating, mounting, and locking. If the BOM calls for 12 circuits, the S12B-ZR variant is the drop-in; if the layout has 11 positions, this is the one.
