ACH-series - Wire-to-Board Crimp connector, pitch 1.2mm

The new ACH Series Wire-to-Board connector recently introduced by JST, was originally designed for a DC power supply application and has a 2.0 Amp current rating for both the 2 and 3 circuits using wire size 28 AWG.

These low-profile connectors have a height of only 1.4mm and a width of 4.3mm. Uniquely constructed, these 1.2mm (.047”) pitch, wire-to-board connectors feature a socket half that is mated with the header from the vertical direction, while the wires come out from the horizontal direction of the socket connector. The ultra-compact, low-profile design provides the flexibility for applications that need high-performance connectors in tight spaces.

The ACH disconnectable, crimp-style connector series is currently available in 2 and 3 circuits rated 2.0 A (AC/DC, #28 AWG) at 50 V AC/DC. Wire sizes from #30 to #28 AWG are accommodated. Temperature range is -25 C to +85 C (including temperature rise in applying electrical current). Header plating is lead free and complies with European RoHS directive. Headers are provided on embossed tape for automatic insertion equipment.

The housing material of the header consists of heat resisting resin. The header pins are made of copper alloy with a nickel underplating and gold plated surface finish.

The material of the socket housing is PBT. Also the crimp contacts are made of copper alloy with a nickel underplating and gold plated surface finish.
