JST Cable Assemblies
JST's crimp-style wire-to-board connectors are a common choice for small, keyed, low-current connections: sensor boards, battery packs, motor drivers, cameras and the boards inside robots and drones. Four series cover most requests — SH at 1.0 mm pitch, GH at 1.25 mm with a positive lock, PH at 2.0 mm and XH at 2.5 mm. Our manufacturing partner crimps and assembles JST leads and harnesses to your drawing with genuine JST housings and terminals.
Where JST assemblies are used
Sensor and battery leads
PH and XH leads for sensors, battery packs and power boards; the XH's wider pitch takes heavier wire.
Robots, drones and gimbals
GH and SH leads where boards are small and the connection has to stay put under vibration; GH adds a latch.
Internal harnesses
Harnesses that land JST plugs on several boards from one trunk, keyed and labeled.
What you can specify
Each point is confirmed with our manufacturing partner before the quotation. Connectors are the genuine parts your drawing names, and an alternative is used only with your written approval.
- Series and position count for each plug
- Wire gauge and insulation within the series' range
- Lengths, twisting, and whether pin 1 meets pin 1 or the order reverses
- The far end: another JST series, a Molex or Hirose connector, or tinned leads
- Sleeving, heat-shrink and labels
Testing and records
Every unit is continuity tested and ships with a test report; crimp pull-force testing follows the plan agreed in your quotation.
Continuity checks each circuit pin to pin, which also catches a lead built with its pin order reversed.
How testing and records work →Common questions
Do you use genuine JST connectors?
Yes. Housings and terminals are genuine JST parts unless you approve a named alternative in writing, and the quotation lists their part numbers.
How do I tell PH, XH, GH and SH apart?
By pitch first — measure from one contact to the next: 1.0 mm is SH, 1.25 mm is GH, 2.0 mm is PH and 2.5 mm is XH. Other series share some of those pitches, so a housing part number or a photo next to a ruler settles it.
Will a JST plug mate with another maker's header of the same pitch?
Not as a rule. JST GH and Molex PicoBlade are both 1.25 mm, for example, and still different systems. The header's part number decides what the plug must be.
What should a JST cable RFQ include?
Series and position count at each end, housing part numbers if you have them, wire gauge and colors, lengths, the pin-to-pin table, sleeving or labels, and quantities.
