Helukabel KM-EMV M12x1.5 EMC Brass Locknut

The Helukabel KM-EMV M12x1.5 EMC brass locknut is a precision-engineered component designed to provide secure and reliable fastening for EMC cable glands in industrial electrical installations. Constructed from high-quality nickel-plated brass, this locknut is specifically engineered to maintain electromagnetic compatibility by ensuring consistent grounding and shielding performance. Its robust design incorporates specialized cutting edges that effectively penetrate painted surfaces, establishing a direct metal-to-metal contact necessary for optimal equipotential bonding.

Advantages

This locknut offers superior mechanical stability and enhanced vibration resistance, making it an ideal choice for demanding industrial environments where equipment is subject to constant movement or mechanical stress. The nickel-plated brass construction provides excellent corrosion resistance, ensuring long-term durability and reliable electrical conductivity. By facilitating a secure connection that cuts through non-conductive coatings, it simplifies the installation process while guaranteeing that the shielding requirements of sensitive electronic systems are met without the need for additional surface preparation.

Suitable for

• Securing EMC cable glands in industrial control panels
• Establishing reliable grounding in electrical enclosures
• Applications requiring equipotential bonding through painted surfaces
• Environments with high levels of vibration

When it may not be suitable

This locknut is designed specifically for metric M12x1.5 threads and will not fit cable glands with different thread sizes or types. It is intended for use with metallic surfaces or applications where electrical continuity is required; it may be unnecessary for simple, non-shielded cable routing where EMC protection is not a factor.

Key specifications

• Thread size: M12x1.5
• Material: Nickel-plated brass
• Features: Integrated cutting edges for surface penetration
• Resistance: Increased vibration resistance

How to use

To install the Helukabel KM-EMV locknut, slide the cable gland through the enclosure wall and thread the locknut onto the gland from the inside. Tighten the locknut using an appropriate wrench. As the locknut is tightened, the integrated cutting edges will bite into the surface of the enclosure, removing any paint or insulating coating to establish a secure electrical connection for grounding purposes. Ensure the locknut is tightened firmly to maintain the integrity of the vibration-resistant connection.

What to consider before purchase

• Verify that your cable gland has a matching M12x1.5 metric thread
• Ensure the enclosure material is compatible with the cutting edges of the locknut
• Confirm that the application requires EMC shielding and grounding

Usage recommendations

For optimal performance and safety, ensure that the mating surface is clean and that the locknut is tightened to the manufacturer's recommended torque specifications to maintain the vibration-resistant properties.
