SKU CH-3YCR-BJXBJ

A 360-piece JST MX 1.25 mm pitch connector kit with 2-to-5-pin male and female housings plus 140 male and 140 female tin-plated terminals for 28 AWG wire

  • ColorBlack
  • 360-piece kit covers 2/3/4/5-pin JST MX needs
  • 140 male and 140 female terminals support 28 AWG wire
  • Tin-plated copper terminals ensure reliable conductivity
  • Nylon housings resist oxidation from -25°C to +85°C
  • 25 mm pitch fits Pixhawk flight controllers and video transmitters

Versatile JST MX 1.25mm Kit

This 360-piece assortment supplies 2, 3, 4 and 5-pin male and female housings plus matching terminals. It suits hobbyists and technicians building or repairing small-gauge wiring harnesses for drones, flight controllers and sensor modules. The 1.25 mm pitch matches common JST MX series footprints.

Replaces Soldered Joints

Use this kit when you need serviceable connections instead of permanent solder links on 28 AWG wire. The jump is worth it whenever a module such as GPS, telemetry or optical-flow sensor must be swapped without reworking the loom. Tin-plated copper terminals ensure reliable conductivity through repeated mating cycles.

Check Wire Gauge And Tooling

Verify that all conductors are 28 AWG; larger gauges will not fit the supplied terminals. Confirm you have a crimp tool rated for the MX 1.25 mm series before ordering. The nylon housings and phosphor-bronze terminals are rated from -25 °C to +85 °C, so ensure the operating environment stays within that range.

Questions about this item

What wire gauge fits the 1.25mm pitch terminals in this kit?

The terminals accept 28 AWG wire. Strip the insulation to the crimp length, seat the terminal in the crimper jaws, and compress fully before inserting into the housing.

How do I crimp the phosphor-bronze terminals onto 28 AWG wire without damaging the nylon housing?

Crimp each terminal on the bare conductor first, then push the crimped terminal into the male or female housing until the locking lance clicks; do not crimp with the housing already in place.

When should I replace a connector from this assortment after repeated mating cycles?

Replace any housing or terminal that shows cracked nylon, bent locking lances, oxidised tin plating, or intermittent continuity when operated within the –25 °C to +85 °C range.
