描述

The 91902-1 is a bottoming die assembly for TE Connectivity's CERTI-CRIMP hand crimping tools, engineered to guarantee proper and repeatable crimp force application to terminals. This component is critical for maintaining consistent crimp performance by ensuring the correct compression and reduction of the cross-sectional area of both wire and terminal stock. The bottoming die works in conjunction with a ratchet system and handle pressure mechanism to deliver precise crimp heights and mechanical stability that meet specification requirements. Regular maintenance and certification of the tool, including verification of the bottoming die condition on an 8-month or 1,000-cycle basis, ensures long-term consistency and electrical conductivity in crimped connections. This component is essential for production environments requiring certified crimp quality and repeatability in terminal assembly operations.
