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. ## Active Production — No Lifecycle Concern","metaTitle":"JST B12B-ZR-SM4-TF(LF)(SN) ZH Header 12 Pos 1.5mm SMT","metaDescription":"JST ZH series header, 12 positions, 1.50 mm pitch, SMT, shrouded 4-wall, detent lock, 1 A, 50 V.
