Proper crimping is more than squeezing a terminal over a wire. TE Connectivity’s crimp designs are highly engineered for superior performance over other tools. They incorporate percent of compression that optimizes both electrical and mechanical performance. Repeatability in consistently reducing Circular Mil Area is the real measure of a crimp tool. The entire design of the tool; crimp form, force application, materials, and manufacturing tolerances, ensures that dies fully bottom, independent of operator technique or fatigue, or tool wear. And the reliable ratchet system built into all CERTI-CRIMP II tools is an aid to the operator, making sure the die bottoms before the tool opens. It complements the actual tool and die design in ensuring crimp repeatability.
