The Ergom Polyamide Cable Gland M20 IP68 DP-EN 20 HM BK is a professional-grade component engineered to provide secure cable entry and robust strain relief for various electrical installations. Constructed from high-quality polyamide, this black cable gland is designed to withstand mechanical stress while maintaining a reliable seal against environmental factors. Its M20 thread size makes it a versatile solution for standard industrial enclosures and junction boxes, ensuring that cables remain firmly in place and protected from external damage.

Advantages

This cable gland offers exceptional durability and resistance to harsh conditions, thanks to its high-grade polyamide construction. The IP68 protection rating guarantees that the connection is completely dust-tight and protected against the effects of immersion in water, making it suitable for demanding outdoor or industrial environments. Its design facilitates easy installation while providing superior mechanical protection, which helps in preventing cable pull-out and maintaining the overall integrity of the electrical system.

Suitable for

• Industrial control panels and electrical cabinets
• Outdoor junction boxes and distribution enclosures
• Machinery and equipment requiring secure cable management
• Installations where dust and moisture protection is critical

When it may not be suitable

This product is designed for standard M20 threaded openings and may not be compatible with enclosures requiring different thread sizes or types. It is intended for use with specific cable diameters and may not provide an effective seal if the cable is too thin or too thick for the gland's clamping range.

Key specifications

• Thread size: M20
• Material: Polyamide
• Protection rating: IP68
• Color: Black
• Function: Cable entry and strain relief

How to use

To install the cable gland, insert the threaded body through the pre-drilled hole in the enclosure wall and secure it firmly using the provided locknut from the inside. Once the body is fixed, pass the cable through the gland. Tighten the dome nut by hand or with a suitable wrench until the internal seal compresses around the cable jacket, ensuring a snug fit that prevents movement and moisture ingress. Ensure that the seal is properly seated to maintain the IP68 rating.

What to consider before purchase

• Verify that the M20 thread size matches your enclosure's mounting hole.
• Check the diameter of your cable to ensure it falls within the clamping range of the gland.
• Consider the environmental conditions of the installation site to ensure polyamide material is appropriate.

Usage recommendations

For optimal performance and to maintain the IP68 seal, ensure that the cable is inserted straight and that the dome nut is tightened evenly. Avoid over-tightening, which could damage the plastic threads or the internal sealing gasket.
