Helukabel KM-EMV Brass EMC Locknut M20 x 1.5

The Helukabel KM-EMV brass EMC locknut M20 x 1.5 is a high-performance component engineered for secure and reliable cable gland installation in demanding industrial environments. Constructed from nickel-plated brass, this locknut is specifically designed to maintain electrical conductivity and electromagnetic compatibility, ensuring that your cable assemblies remain protected against interference. Its robust design incorporates specialized cutting edges that penetrate painted surfaces, establishing a direct, low-resistance contact for equipotential bonding.

Advantages

This locknut offers superior mechanical stability and enhanced vibration resistance, making it an ideal choice for machinery and equipment subject to constant movement or mechanical stress. The nickel-plated brass construction provides excellent corrosion resistance and durability, ensuring a long service life even in harsh operating conditions. By facilitating a reliable electrical connection through its integrated cutting edges, it simplifies the process of achieving effective shielding continuity without the need for additional surface preparation.

Suitable for

• Securing EMC cable glands in industrial control panels
• Electrical installations requiring electromagnetic interference protection
• Applications involving painted metal enclosures where equipotential bonding is necessary
• Machinery and automation systems with high vibration levels

When it may not be suitable

This locknut is designed specifically for M20 x 1.5 threaded applications and will not fit other thread sizes. It is not intended for use in environments where brass is chemically incompatible with the surrounding atmosphere or where non-metallic, plastic-only installations are required.

Key specifications

• Thread size: M20 x 1.5
• Material: Nickel-plated brass
• Features: Integrated cutting edges for paint penetration
• Vibration resistance: Increased

How to use

To install the Helukabel KM-EMV locknut, slide the cable gland through the mounting hole of your enclosure. Thread the locknut onto the gland from the inside of the housing. As you tighten the locknut using an appropriate wrench, the integrated cutting edges will bite into the surface of the enclosure, effectively removing any paint or coating to establish a secure electrical contact for grounding and shielding purposes.

What to consider before purchase

• Verify that your cable gland and enclosure hole are compatible with the M20 x 1.5 thread size.
• Ensure the enclosure material is suitable for the cutting action of the locknut.
• Check if the application requires specific torque settings for the installation.

Usage recommendations

For optimal performance and shielding continuity, ensure that the locknut is tightened sufficiently to allow the cutting edges to make full contact with the conductive base material of the enclosure.
