Helukabel EMC Brass Cable Gland Nut M40x1.5

The Helukabel EMC Brass Cable Gland Nut M40x1.5 is a high-quality industrial component designed to provide secure and reliable fastening for cable glands in environments where electromagnetic compatibility is essential. Constructed from nickel-plated brass, this locknut is engineered to maintain mechanical stability while ensuring consistent electrical conductivity. Its specialized design features integrated cutting edges that allow it to penetrate painted surfaces, establishing a direct and effective contact for equipotential bonding.

Advantages

This locknut offers superior performance in demanding industrial settings by providing increased vibration resistance, which ensures that cable connections remain tight and secure over long periods of operation. The use of nickel-plated brass provides excellent corrosion resistance and durability, making it suitable for harsh environments. By facilitating a reliable electrical connection through its cutting-edge design, it simplifies the installation process for EMC-compliant systems, reducing the need for manual surface preparation.

Suitable for

• Securing EMC-compliant cable glands in industrial machinery
• Applications requiring reliable equipotential bonding
• Environments with high vibration levels
• Electrical installations on painted metal enclosures

This product may not be suitable for applications involving non-metallic enclosures where the cutting edges cannot establish an electrical contact. It is also not intended for use in environments with extreme chemical exposure that could degrade the nickel plating over time.

Key specifications

• Thread size: M40x1.5
• Material: Nickel-plated brass
• Features: Integrated cutting edges for surface penetration
• Vibration resistance: Increased

To use the Helukabel EMC brass locknut, thread it onto the cable gland after the gland has been inserted through the enclosure wall. Tighten the nut using an appropriate wrench until the integrated cutting edges have successfully penetrated any paint or coating on the enclosure surface. This action ensures the necessary metal-to-metal contact required for effective electromagnetic shielding and equipotential bonding.

What to consider before purchase

• Verify that the enclosure wall thickness is compatible with the thread length
• Ensure the M40x1.5 thread size matches your existing cable gland
• Confirm that the surface material of the enclosure is conductive metal

Usage recommendations: Always ensure that the locknut is tightened to the manufacturer's recommended torque to maintain the integrity of the vibration resistance and electrical contact. Regularly inspect the connection during routine maintenance to ensure no loosening has occurred due to external mechanical stress.
