The product is ACH connector of JST company, which is a compact and low-profile 1.2mm pitch wire-to-board connector. Features are top entry but side feed type, socket is mated with header from vertical direction of connector, excellent workability, connector for DC power supply, with rated current of 2A, corresponding to sucking nozzle of pick and place machine.
The ACH connector is a compact, low‑profile wire‑to‑board connector with a 1.2 mm (0.047") pitch. It features a height of 1.4 mm (0.055") and a width of 4.3 mm (0.169"), offering a 2 A current rating for both 2‑circuit and 3‑circuit configurations and a 50 V AC/DC voltage rating. The connector is designed for DC power supply applications and includes a sucking area on the bottom of the header for pick‑and‑place machines.
The datasheet lists detailed electrical specifications, material finishes, and tape and mounting dimensions. It specifies applicable wire sizes (AWG #30 to #28), insulation outer diameter, contact and insulation resistance, withstanding voltage, and temperature range from –25 °C to +85 °C. Material information includes a copper‑alloy, nickel‑undercoated, gold‑plated contact and a PBT housing (UL94V‑0, natural white).
