7AJST Connectors refers to a family of electrical connectors made by the Japanese company JST.

JST Connectors in their most-recognizable form are white plastic connector housings and headers on PCBs, but JST also makes sealed automotive connectors.

JST Connectors are usually described using the series, pin-to-pin pitch, wire count and gender. For example, a 3 pin female JST XH connector would be described as:

  • JST XH 2.5mm 3-pin female
