The decision to purchase a suitable crimper for joining connectors to data cables must be made carefully. You will need to focus on the crimping tool requirements to ensure that the tool specifications are right for the project. It can be a daunting task as there are a myriad of types of crimpers used to terminate connectors, all made to certain specifications, with varying features and varying costs.
Tools used with telecommunications cables generally accommodate Registered Jack (RJ) modular connectors that interface with telephones, telephone wall jacks, and telephone equipment. For example, modular jacks are made to accommodate one, two, and three line services with descriptions such as 6P2C, 6P4C, and 6P6C respectively. Additionally, connectors and tools can be labeled to match types, such as RJ11, RJ12, RJ14, and RJ25.
Connectors are manufactured to strict telecommunications standards to interface with sensitive electronic equipment. Therefore, it is advisable to purchase a good quality crimper to improve the success rate of termination. Additionally, a premium crimp tool can last a significant period of time if operated correctly.
The overall shape of the tool can vary for many reasons, such as to allow better access in tight and awkward crimping areas, for example, both vertical and right angle crimping tool models are available. Please note that cabling connections should be checked with a network cabling tester to ensure quality.
Most premium CAT6 network tools have a built-in ratcheting mechanism to ensure smooth operation for connection as well as reduce hand fatigue during continuous use. Another benefit of the ratcheting design is that excellent insulation penetration is achieved. Additionally, a quality jaw design will distribute optimum uniform pressure to all contacts simultaneously during termination.
Crimp tools can be specifically designed to fit one modular plug type or several different types, for example a 3-in-1 tool might have three individual sets of crimping dies for 6-pin, 8-pin and 10-pin. However, this mainly depends on the individual installer and the specific work scenario. Also, professional installers may have a dedicated RJ45 crimp tool simply for its reliability and ease of use. Also, 10-pin or RJ50 connections are less common today, so a tool with only 10P10C capability may be preferred.
Tools can have various optional features built into the design, such as a wire stripper and wire cutter. The latest features are ideal for anyone installing cabling, from professional Information and Communications Technology (ICT) cabling installers to weekend computer hobbyists. Although more serious installers will need a dedicated cable insulation stripper to ensure optimal connectivity is achieved.
Krone tools or IDC crimp tools are used for terminating Insulation Displacement Connectors (IDCs) on twisted pair telecommunications and Ethernet cables. The design and action of the Krone termination tool is different than the crimpers mentioned above. Additionally, Krone-style tools require a punching action, very different from tightening a ratchet handle for connector termination. For example, a mode 3 safety IDC plug is terminated with Krone type tools.
IDC tools can include integrated support accessories on the side. In order to assist the installer during the installation of the IDC jacks. IDC connectors are completely different from the design of modular plugs, so the tools are not interchangeable with each other.
