An IWISS SN-025 ratcheting crimp tool for Molex and TE signal terminals, covering 0.1 to 1.0 mm² conductors.
A crimp is a gas tight cold weld, or it is nothing. Taken to full compression with the right die, the terminal and the conductor deform into one piece of metal with no air between them, and the joint outlives the cable. Done with pliers, it is a mechanical grip that looks identical, passes a tug test, and fails eighteen months later once moisture has found its way in. Signal circuits are where this hurts most, because the currents are too small to reveal a poor joint until it becomes an intermittent fault that takes a day to find.
The ratchet is the feature, not a convenience. It will not release until the crimp has reached full compression, so every terminal comes out the same regardless of who squeezed the handles, and regardless of how many hundreds into a loom you are.
Terminal families that look alike often need different dies. This one spans the Molex ranges plus TE Superseal 1.0, which is the sealed automotive family you meet on sensors and small actuators.

Features
- Ratcheting action that will not release until the crimp is complete
- Correct die profile for Molex and TE signal terminals
- Repeatable results across a whole loom, not just a careful first few
- Nylon handles, sized for repeated use rather than occasional
Compatibility
For Molex 2.54 mm to 3.96 mm, Molex CP, Molex C-Grid III 90119 series, Dupont, and TE Superseal 1.0 on 0.1 to 1.0 mm² conductors.
It is a small signal tool. It does not crimp high voltage terminals, battery lugs or anything from 4 mm² upwards, which need a hydraulic or heavy ratchet crimper with hex dies.
Check a test crimp before you do a batch. Crimp one, cut through it, and look: a correct crimp shows solid metal with no visible voids and the insulation grip closed separately from the conductor grip. It takes two minutes and saves remaking a loom.
