描述

539783-1 is a bottoming die component used in crimp tooling systems to guarantee proper crimp force application during wire terminal crimping. The die is engineered to control the compression and reduction of cross-sectional area of both wire and terminal, ensuring consistent crimp height and mechanical stability. According to certification documentation, this component operates with a handle force range of 40–47 lbs and achieves a crimp height specification between 38.18 and 498 units (as-received condition: 452 units; after crimp: 389 units). The bottoming die is critical for maintaining long-term consistency in crimping production, confirming specified tensile strength, mechanical stability, and electrical conductivity. This component is commonly used in TE Connectivity's CERTI-CRIMP tooling systems and is supported by field service certification and recertification protocols to maintain performance standards.
