2-455889-0 is a crimp tooling component used in wire termination processes to form electrical connections between wires and terminal barrels. The tooling operates based on precise dimensional control of crimp height (CH) and crimp width (CW) to achieve the target Area Index (AI), typically designed at 80% to ensure proper electrical and mechanical performance. Key dimensional parameters include crimp height of approximately 0.068 to 0.073 inches and crimp width around 0.110 inches, with crimper leg taper of approximately 3.0 degrees and anvil width of 0.109 inches. The tooling requires strict dimensional tolerances (±0.002 inches on crimp height) and clearance control (nominal 0.005 inches anvil-to-crimper clearance) to minimize flash and ensure consistent termination quality. This component is critical in production environments where crimp symmetry, pull test values, and lead throughput rates must be monitored and maintained to meet connector assembly specifications.
