  • Crimping hole to install RJ50 6 Pin connector.
  • Crimping hole to install RJ48 8 Pin connector.
  • Crimping hole to install RJ12 4 Pin connector.

Generally, a crimping plier is used to install an RJ45 connector, depending on the crimping pliers’ type.

2. Crimper

Crimper is a part to clamp and implant cable on the connector. Crimper will work when the plier handle is pressed, insert the cable and connector on the crimping hole first.

3. Wire Stripper

Problems on Crimping Plier

There are several problems that can emerge on crimping plier, such as:

  • The blade of the wire cutter is dull or not sharp. That thing can happen because of the age factor of the old crimping plier.
  • The wire cutter does not fit or is not precise. The wire cutter that does not fit causes the cable pad to slip, and it is hard to do the cutting process.
  • Corroded wire cutter. Corroded wire cutter can happen because the stainless steel coating is peel off, so the rust appears, or it can be because of the age factor of the crimping plier.
  • The crimper part is not precise. The crimper part that does not precise cause the crim result to not fit, so the cable can easily be separated from the connector. Sometimes, it also needs bigger pressure, so the tip of the pin can stick on the brass wire. The bigger pressure can cause the connector to be broken or cracked.

Correct handling and proper storage of crimping pliers can minimize problems that can occur on your crimping pliers. Always take care of your crimping pliers to make them durable and long-lasting.
