Common JST Connector Types

March 12, 2024 / Sam Tang

JST is short for Japanese Solderless Terminal. It's a Japanese connector manufacturer founded in 1957. It has a wide selection of connetors. Thus JST connector is not a connector type, but a one of different types of connectors manufactured by JST.

Common JST connector types:

  • SH ( pitch: 1.0mm / 0.039 inch) what is pitch size?
  • GH (pitch: 1.25mm / 0.049 inch)
  • ZH (pitch: 1.50mm / 0.059 inch)
  • PH (pitch: 2.0mm / 0.079 inch)
  • PA (pitch: 2.0mm / 0.079 inch)
  • XH (pitch: 2.50mm / 0.098 inch)
  • XA (pitch: 2.50mm / 0.098 inch)
  • SM (pitch: 2.50mm / 0.098 inch)
  • EH (pitch: 2.50mm / 0.098 inch)
  • VH (pitch: 3.96mm / 0.156 inch)

Why are these common types of JST connectors? I believe they are widely used in daily consumer products and are easy to use for engineers and amateurs alike. For instance, when you have a low-cost handle crimp tool to create connections, they become even more accessible. Moreover, there are numerous topics on the internet about them, indicating their prevalence.
