Wago 791-117 Spring Shield Clamp for 10-17mm Screens, Silver

The Wago 791-117 spring shield clamp is a professional-grade component engineered for secure and reliable cable shielding in complex electrical installations. Designed to accommodate screen diameters between 10mm and 17mm, this silver-colored clamp provides a consistent, high-pressure connection that ensures optimal grounding and effective protection against electromagnetic interference. Its robust construction supports the integrity of signal transmission in industrial and commercial wiring systems.

Advantages

The primary benefit of this shield clamp is its spring-loaded design, which automatically adjusts to the cable diameter to maintain constant contact pressure, even in environments subject to vibration. This ensures long-term electrical stability without the need for manual retightening. The high-quality materials used in its construction offer excellent conductivity and resistance to environmental factors, making it a dependable choice for maintaining signal integrity in sensitive electronic equipment.

Suitable for

• Securing cable shields in industrial automation systems
• Grounding applications in control cabinets
• Protecting signal cables from electromagnetic interference
• Professional electrical installations requiring high reliability

When it may not be suitable

This clamp is specifically designed for screen diameters ranging from 10mm to 17mm. It is not suitable for cables outside of this diameter range or for applications requiring mechanical strain relief beyond standard shielding purposes.

Key specifications

• Compatible screen diameter: 10mm to 17mm
• Material: High-conductivity metal
• Color: Silver
• Mounting type: Spring-loaded clamp

How to use

To install the Wago 791-117, ensure the cable screen is properly prepared by stripping the outer insulation to expose the shielding braid. Open the spring clamp and position it over the exposed screen area. Once released, the spring mechanism will exert the necessary pressure to establish a secure electrical connection between the shield and the grounding point. Ensure the clamp is seated firmly to provide maximum contact surface area.

What to consider before purchase

• Verify the exact diameter of your cable screen to ensure it falls within the 10-17mm range
• Confirm the mounting surface is compatible with the clamp design
• Assess the environmental conditions to ensure the material is appropriate for your specific installation

Usage recommendations

For optimal performance, ensure that the contact surface is free from oxidation or debris before installation. Regularly inspect the connection during routine maintenance to confirm that the spring tension remains effective.
