Wago 791-111 Spring Shield Clamp for 5-11mm Diameter Cables

The Wago 791-111 spring shield clamp is a professional-grade component engineered to provide reliable electromagnetic interference (EMI) shielding for electrical installations. Designed for precision and durability, this silver-colored clamp ensures a secure connection between cable shields and grounding systems, effectively minimizing signal noise and protecting sensitive electronic equipment in industrial environments.

Advantages

This shield clamp offers a robust spring-loaded mechanism that maintains constant contact pressure on the cable shield, even in environments subject to vibration. Its compact design allows for efficient space utilization within control cabinets and electrical panels. The high-quality construction ensures long-term reliability and consistent shielding performance, which is essential for maintaining the integrity of data and power transmission lines in complex electrical systems.

Suitable for

• Securing cable shields in industrial control cabinets
• Grounding signal and power cables in automation systems
• Reducing electromagnetic interference in sensitive electronic circuits
• Applications requiring reliable contact for cables with diameters between 5mm and 11mm

When it may not be suitable

This clamp is not intended for use with cables outside the specified diameter range of 5mm to 11mm, as this would compromise the contact quality and shielding effectiveness. It is also not designed for structural load-bearing applications or for use in environments with extreme chemical exposure that could degrade the metallic components.

Key specifications

• Cable diameter range: 5mm to 11mm
• Component width: 17mm
• Material: High-quality conductive metal
• Color: Silver
• Mounting type: Spring-loaded clamp

How to use

To install the Wago 791-111, ensure the cable shield is properly exposed by removing the outer insulation jacket at the point of contact. Position the clamp over the shielded area and press it firmly onto the mounting surface or rail. The spring mechanism will automatically adjust to the cable diameter, ensuring a secure and conductive connection between the shield and the grounding point.

What to consider before purchase

• Verify that your cable diameter falls strictly within the 5mm to 11mm range.
• Ensure there is sufficient space on your mounting rail or panel for a 17mm wide component.
• Confirm that the grounding surface is clean and conductive to achieve optimal shielding results.

Usage recommendations

For the best performance, ensure that the cable shield is clean and free of oxidation before installation. Regularly inspect the connection points during routine maintenance to ensure the spring tension remains consistent and the grounding path is unobstructed.
