The 69561-4 is a bottoming die assembly for TE Connectivity's CERTI-CRIMP crimping tools, engineered to guarantee proper crimp force application and repeatability in terminal crimping operations. This component is critical for maintaining consistent crimp performance by controlling the compression and reduction of the cross-sectional area of both wire and terminal during the crimping process. The bottoming die works in conjunction with a ratchet system and handle pressure mechanism to ensure the operator applies the correct force according to terminal designer 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 maintain crimp quality and meet industry standards. The 69561-4 supports the production of reliable electrical connections with specified tensile strength, mechanical stability, and electrical conductivity. This component is essential for manufacturers requiring certified crimp tooling documentation and consistent quality assurance in wire processing applications.
