A slim, reliable 1.25 mm pitch cable with 9-pin connectors on both ends and a 20 cm length. The friction-lock connectors provide a secure, satisfying click for lightweight connectivity where standard 0.1" headers or JST PH connectors are too bulky.

This cable uses 1:N reversed wiring, meaning pin 1 on one connector maps to pin 9 on the other, pin 2 to pin 8, and so on. Molex PicoBlade compatible.

Key Features

  • 1.25 mm Pitch Connectors – Ultra-slim profile for space-constrained builds
  • 1:N Reversed Wiring – Pin order is mirrored from one end to the other
  • Friction-Lock Mechanism – Secure, click-in connection that won't pull loose
  • 20 cm Length – Convenient short-run cable for internal wiring
  • 9 Pins – Suitable for multi-signal connections
  • Molex PicoBlade Compatible – Works with standard 1.25 mm pitch connectors

Ideal For

  • Connecting breakout boards and sensors with 1.25 mm pitch headers
  • Internal wiring in compact enclosures and portable projects
  • Replacing bulkier JST PH or 0.1" dupont connections

Package Contents

  • 1× 1.25 mm pitch 9-pin cable (20 cm, 1:N wiring)
Note: This cable uses 1:N (reversed) wiring. Pin 1 connects to pin 9, pin 2 to pin 8, etc. If you need straight-through 1:1 wiring, check the 1:1 cable variants.

Jargon buster

Plain-language definitions for the technical terms used above.

breakout
A breakout board carries a small or fine-pitched component and brings its connections out to standard, breadboard- and header-friendly pins. Describing a part as a breakout means it can be wired into a project without soldering directly to the component's tiny contacts.
Headers
Rows of connector contacts on a fixed pitch (commonly 2.54 mm) used to link a board to a breadboard, jumper wires, or another board. They come as male pin headers and female socket headers; when a module ships with pre-soldered headers it can be used straight away, whereas bare pads require soldering the pins yourself.
JST PH
A small keyed plug-and-socket connector with 2 mm pin spacing, often used for low-power electronics connections. You need the correct JST PH cable, and its current rating limits how much power should be passed through it.
pH
A measure of how acidic or alkaline a liquid is, on a scale where 7 is neutral. For a water monitoring kit, pH tells you about water chemistry and whether the included probe matches the range and accuracy your project needs.
