Crimping Guide
- Strip 3–4mm of insulation from the wire end.
- Insert the wire into the terminal crimp barrel under a microscope or magnification if needed (1.0mm pitch terminals are very fine).
- Crimp using a precision ratchet crimping tool with the appropriate 1.0mm MX23A series die.
- Inspect the crimp under magnification to verify correct wire barrel and insulation barrel engagement.
- Insert the crimped terminal into the MX23A connector housing until it clicks into the retention position.
