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 (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
