Cable Gland Ergom DP-EN 20 HM M20 polyamide IP68 gray

Ergom DP-EN 20 HM M20 polyamide cable gland in gray provides IP68-rated protection for cable entries where waterproofing and dust-tight sealing are required. Designed for securing and sealing single cables, this gland offers mechanical retention and strain relief to maintain the integrity of electrical and electronic enclosures in outdoor and industrial environments. The polyamide construction ensures chemical and UV resistance while keeping the component lightweight for easy installation.

Advantages

The polyamide body and sealing components deliver reliable protection against water ingress and particulate contamination in wet or dusty conditions. IP68 classification ensures continuous immersion resistance to specified depths, while the M20 thread size provides compatibility with standard metric conduit entries and glands. The design enables effective strain relief to prevent cable movement and reduce stress on terminations, and the neutral gray color allows discreet integration into panels and junction boxes.

Suitable for

• Sealing cable entries in outdoor enclosures and junction boxes
• Industrial machinery and control cabinets exposed to dust and moisture
• Conduit and cable management systems requiring M20 metric glands
• Applications where mechanical cable retention and strain relief are needed

Key specifications

• Material: polyamide (nylon) housing and components
• Protection rating: IP68 for dust-tight and continuous immersion resistance
• Thread size: M20 metric male thread for standard panel or conduit entries
• Color: gray
• Function: cable sealing, strain relief and mechanical retention

How to use

Drill or use an existing M20 threaded entry in the enclosure or panel, insert the gland body from the outside and secure it using the internal locking nut or mating threaded hole. Pass the cable through the gland and tighten the sealing nut until the elastomeric seal compresses around the cable, ensuring a watertight and dust-tight seal. Confirm that the gland provides adequate strain relief by checking that the cable cannot be pulled free under reasonable force. Follow standard electrical installation practices and local regulations while routing and terminating the cable.

Usage recommendations

Choose the correct cable diameter variant of the gland to maintain IP68 performance; avoid over-tightening the sealing nut to prevent damage to the polyamide parts and the cable insulation. For installations exposed to prolonged UV or aggressive chemicals, verify material compatibility with the operating environment and perform periodic inspections to ensure sealing integrity.
