When a crimping tool is used on a terminal, two crimps take place at the same time. One is the electrical connection between conductor and terminal. The other is the insulation crimp which provides strain relief against vibration and tension. It is important that the electrical connection is gas tight without any voids between the wire strands and the terminal. If there any voids present, then corrosion can occur causing resistance and excessive heat which damages the electrical connection. Using a good quality crimping tool will ensure that a full, gas tight crimp is produced preventing future deterioration of the electrical connection and insulation breakage

From TE Connectivity an ERGOCRIMP commercial grade hand operated crimping tool frame assembly designed to accept a wide range of interchangeable SDE die assemblies. Commercial grade hand crimping tools incorporate features for long lasting performance including a construction of durable high-carbon steel and extra strength pivot pins. The head of the crimping tool is angled to reduce hand-stretch and to allow an easier view of the crimp area. The handles have a reduced handle force and an ergonomic design reducing operator fatigue and making the tool easy and comfortable to use.
The tool frame has two handles and jaws (stationary and moving) and an adjustable ratchet with emergency ratchet release. The jaws of the tool frame are slotted for easy insertion of the die assemblies which are secured in place by two screws.

Commercial grade crimp tools use SDE (Standard Die Envelope) technology. SDE technology enables the dies to be used in different types of tooling within the same SDE system including, manual, battery, pneumatic and electric tools. There is no need to have separate dies fitted to each type of tool, saving time and costs. The dies are easily swapped from one type of tool to another by removing two screws

This ERGOCRIMP crimp tool features a ratchet mechanism which controls the amount of handle pressure that is exerted on the jaws during crimping. The ratchet stays locked until the handles of the tool are fully closed and the dies are bottomed. This feature prevents partial crimps by ensuring that a full crimping cycle is achieved and enables the operator to repeatedly produce consistent, high-quality crimps. The ratchet can be adjusted by the operator using an adjustment wheel. An emergency ratchet release allows the operator to open the handles of the crimp tool at any point during the crimping cycle when necessary

• High carbon-steel construction for durability
• Extra strength pivot pins
• Ratchet control ensures that a full crimp cycle is achieved
• Emergency ratchet release
• Ratchet adjustment wheel
• Standard Die Envelope (SDE) for flexibility and cost savings
• Accepts a full range of interchangeable dies
• Angled head and ergonomic handles for user comfort

The versatility of the SDE technology allows ERGOCRIMP tools to be taken from bench to production or into the field. Applications include R and D prototyping, networking applications, field installation work and on-site repairs in industrial, commercial or institutional applications.

Are Dies Included?
No, the die assemblies need to be purchased separately, see stock numbers 168-0557, 876-2355, 876-2113 and 876-2071 typically. The dies are supplied with a suitable locator assembly
