The YC series are easy to use ratchet style hand tools for crimping PSI series loose piece crimp contacts on to wire. The YC series has precision ground dies with two crimping sections (A & B) for producing accurate, high-quality crimps. The ratchet mechanism only releases when the handles of the hand crimp tool are fully closed. This ensures a full crimp cycle is achieved and avoids partial crimps.

• Ratchet mechanism ensures full crimp cycle
• High-quality precision ground dies with 2 crimping sections
• Safe operation

The YC-225R crimp hand tool is used to crimp 20 to 16 AWG PSI series socket contacts onto wire.
The YC-335R crimp hand tool is used to crimp 26 to 22 AWG PSI series socket contacts onto wire.
The YC-226R crimp hand tool is used to crimp 20 to 16 AWG PSI series pin contacts onto wire
These crimped contacts are then inserted into the PSI series connector housings
