Component Specifications

Definition
A cable gland, also known as a cable connector or fitting, is a mechanical device designed to securely attach and terminate the end of an electrical cable to electrical equipment, enclosures, or junction boxes. It serves multiple critical functions: providing strain relief to prevent cable pull-out, sealing the entry point against environmental contaminants (dust, moisture, liquids), and ensuring electrical continuity and grounding in some designs. Cable glands are essential for maintaining the integrity and safety of electrical installations in industrial settings.
Working Principle
Cable glands work by mechanically gripping the cable's outer sheath or armor through compression, typically using a threaded body, sealing ring, and compression nut. As the nut is tightened, it compresses the sealing ring against the cable and the gland body, creating a secure, sealed connection that prevents cable movement and ingress of external elements.
Materials
Common materials include brass (general use), stainless steel (corrosive environments), nickel-plated brass, aluminum, and plastic (nylon or polyamide for non-metallic applications). Sealing elements are often made from neoprene, silicone, or EPDM rubber.
Technical Parameters
  • IP Rating IP68 (common for waterproof applications)
  • Thread Size M12 to M75 or NPT equivalents
  • Voltage Rating Up to 1000V AC/DC
  • Temperature Range -40°C to +100°C (varies by material)
  • Cable Diameter Range 3mm to 75mm
Standards
ISO 9001, IEC 62444, DIN EN 50262

Frequently Asked Questions

What is the difference between a cable gland and a conduit connector?

A cable gland secures and seals individual cables, providing strain relief and environmental protection. A conduit connector attaches and seals conduit (tubing) to enclosures, protecting multiple wires inside but not providing direct cable strain relief.

How do I select the right cable gland?

Consider cable diameter, thread size of the entry point, environmental conditions (IP rating), material compatibility (e.g., corrosion resistance), and certifications (e.g., ATEX for hazardous areas). Always match the gland to the cable type (e.g., armored, unarmored).

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
