1.50 mm Pitch, 12-Position SMT Header — Board Layout Fit
The B12B-ZR-SM4-TF(LF)(SN): This is a 12-position, single-row, shrouded header from JST's ZH series, on 1.50 mm pitch.
Current and Voltage — Signal-Duty Ceiling
This is a signal-level interconnect — fine for low-power sensor, I/O, or control signals, but not for power distribution. The detent lock gives a positive tactile click when mated — no secondary latch needed for moderate vibration, but in a high-shock application you'd want a locking ramp or TPA.
Mates with JST ZH series crimp receptacles (e.g., ZR-12P or similar) using the matching crimp terminal. Termination is solder to the board — no crimp tool needed on the header side.
