ACHF Series Wire-to-Board Connectors

JST’s ACHF series wire-to-board, crimp style, disconnectable connectors offer sub-miniature size, design flexibility, and reliable contact construction for high-density applications. These 1.2 mm (0.047”) pitch SMT connectors are polarized and have a secure friction-locking feature when mated. This series is uniquely constructed and features a socket housing that is mated with the header from a vertical direction, while the wires come out of the socket connector in a horizontal direction, thus allowing the placement of the header anywhere on the PCB. An excellent connector for high-density LED light applications, the ACHF series is designed for maximum PCB flexibility with a mated height of only 1.43 mm (0.056”).

The ACHF series is available in 3, 4, and 6 circuits with a 2.5 A (AC/DC) rating using a 28 AWG wire at 50 V AC/DC. Temperature range is -25°C to +85°C including temperature rise in applying electrical current. Headers are molded of RoHS compliant 94V-0 heat-resistant resin material, and contacts are gold-plated (nickel stripe) copper alloy and nickel-undercoated; reinforcements for additional strength are tin-plated, nickel-undercoated copper alloy.

The ACHF series contacts are designed to accommodate a wire range size of 28 AWG to 30 AWG and are gold-plated over nickel-underplated copper-alloy base material. Contacts are offered on standard size reels for semi-automatic or fully-automatic application tooling. SMT headers are provided on embossed tape for automatic insertion equipment.
