601966-4 is a crimp tooling component used in wire termination processes to form electrical connections between wires and terminal barrels. The tooling is designed to achieve precise crimp height (CH) and crimp width (CW) dimensions that maintain an Area Index (AI) of approximately 80%, which is critical for ensuring proper electrical and mechanical connection quality. Key dimensional parameters include a nominal crimp height of 0.073 inches and crimp width of 0.110 inches, with a crimper leg taper of 3.0 degrees and anvil width of 0.109 inches. The tooling requires strict dimensional control to minimize clearance variations and prevent defects such as flash formation during the crimping process. This component is essential in production environments where consistent crimp quality, pull test values, and lead throughput are monitored to ensure reliable termination of electrical connectors.
