For each connector body, the connector manufacturer specifies the crimp tool, die set (hexagonal or round die), crimp sleeve, and crimp force to achieve the best crimp and maximum pull force for that assembly. It’s absolutely critical to use the proper tools and components. The connector manufacturer’s engineers designed this “match made in heaven” with mechanical tolerances in mind. The part of the connector that is crimped usually is not smooth – it is textured and rough because this increases the contact surface area. Such details contribute to the maximum pull force of the total assembly.
