FAQ
Q1: What is JST ACH connector?
A: JST ACH is miniature 1.2 mm pitch low‑profile wire‑to‑board crimp‑style connector, mainly used for compact equipment’s low‑voltage signal and small DC power connection
Q2: What wire gauge fits JST ACH terminals?
A: Standard applicable wire range is 28‑32 AWG. Do not use thicker wire to avoid crimp failure or assembly damage.
Q3: What is the maximum rated current?
A: 2 A for 1‑3‑pin assemblies; 1.5 A for 4‑5‑pin assemblies (28AWG wire). Not for high‑current power loops
Q4: Is JST ACH waterproof?
A: Standard ACH series is non‑waterproof, designed for inside‑enclosure application, not suitable for exposed wet environment.
