The 90546-2 is a bottoming die assembly component designed for use with TE Connectivity's CERTI-CRIMP hand crimping tools. This component is critical to maintaining consistent crimp performance by ensuring proper crimp force is applied to terminals, resulting in specified tensile strength, mechanical stability, and electrical conductivity. The bottoming die works in conjunction with the tool's ratchet system and handle pressure mechanism to compress and reduce the cross-sectional area of wire and terminal combinations according to engineered specifications. Regular maintenance and certification of the tool, including verification of the bottoming die condition, is recommended on an 8-month cycle or every 1,000 cycles to ensure continued crimp quality. This component is essential for production environments requiring reliable, repeatable crimping that meets industry standards and customer specifications.
