The S12B-ZR-SM4A-TF is a 12-position, single-row header from JST's ZH series, pitched at 0.059" (1.50mm) for compact wire-to-board connections.
At 1.50 mm pitch, the 12 positions fit a 16.5 mm board edge footprint — tight enough for dense layouts but still routable on two-layer boards. The shrouded 4-wall design and detent lock keep the mating half aligned and latched under vibration.
The closest match is S12B-ZR-SM4A-TF(LF)(SN) — identical 12 positions, pitch, mounting, and ratings, just a different lead-free suffix. For 11 positions, the S11B-ZR-SM4A-TF(LF)(SN) shares the same form factor.
