Selection Guide
Select the wire section first, then check bolt diameter d2, fork width B and overall length L. Confirm the screw-terminal arrangement and installation torque for the approved assembly.
Use an appropriate non-insulated-terminal crimp tool. Confirm crimp settings, pull-out retention, inspection criteria and any required insulation before approving production.
Applications
Potential uses include compatible screw-terminal connections in control panels, electrical equipment and wire harness assemblies. Product compatibility and qualification depend on the selected model and the approved assembly.
