Connector / Terminal Crimping Pliers

A connector and terminal crimping pliers is a hand tool that secures an insulated or non-insulated terminal, a connector pin or an RJ plug fitted over the end of a conductor to the conductor by crushing it with its die. It is used in panel wiring to crimp insulated and non-insulated cable ends, on JST and Molex type connector ends in internal device harnesses, and to terminate RJ45 and RJ11 plugs in structured cabling. This category includes Isıso, Konsan and Gwest insulated cable end and non-insulated terminal pliers, JST and Molex connector end pliers with AWG sizing, and data pliers suited to RJ45, RJ11 and RJ12 plugs; the terminal pliers state crimping ranges such as 0.5-6 mm² and 1-10 mm². Choose the pliers according to the type of end you will crimp, the conductor cross-section or AWG value, whether the end is insulated or non-insulated, and compatibility with the connector series. Because the cores come out of the front of EZ-type RJ45 plugs, you need an EZ-compatible pliers that trims the excess cores while crimping. The dies for insulated cable ends, non-insulated terminals and RJ plugs are different; these pliers do not replace one another.
