Selection Guide
Start with the conductor section and select the corresponding model group. Match d2 to the bolt or stud, then check fork width B, contact length F, overall length L and sleeve dimensions. Use a crimp tool and die suitable for the terminal and conductor. Send the hardware reference or assembly drawing for selection assistance.
Applications
For compatible screw and stud connections in control panels, equipment wiring, electrical maintenance and cable assemblies. Select the terminal against the conductor, hardware, mechanical clearance and installation requirements of the finished assembly.
Ordering Information
Provide the full SV model reference, conductor size, bolt dimensions and order quantity. Include packaging, labeling and delivery requirements for OEM and wholesale enquiries.
