The ENGINEER PA-09 is a precision micro crimping tool that makes clean, reliable crimps on the small contacts used in fine-pitch connectors — no more mangled contacts from generic pliers that crush instead of crimp. If you regularly work with JST, Molex, or similar small connectors, this tool is a genuine upgrade.
Covers contacts from 1.0 to 1.9mm (AWG #32–20), making it well suited to the frighteningly small contacts in common electronics connectors used in cables, wiring harnesses, and PCB assemblies.
Key Features
- Precision Machined – Purpose-built crimp dies for clean, consistent results
- Contact Range – 1.0 to 1.9mm / AWG #32–20
- Model – ENGINEER PA-09
- Universal Compatibility – Works with a wide range of fine-pitch connector contacts
Ideal For
- Making custom cables and wiring harnesses
- Crimping JST, Molex, Dupont, and similar fine-pitch contacts
- Electronics assembly, prototyping, and repair

Jargon buster
Plain-language definitions for the technical terms used above.
- AWG
- American Wire Gauge is a numbering system for wire thickness, where a lower number means a thicker wire. The AWG rating matters because thicker wire can usually carry more current with less voltage drop and heating.
- PCB
- A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
