Component Specifications

Definition
Cable glands, also known as cable connectors or cord grips, are specialized fittings designed to terminate and secure the end of an electrical cable to equipment such as junction boxes, control panels, or machinery. They serve multiple critical functions: providing a secure mechanical attachment that prevents cable pull-out under tension (strain relief), creating an environmental seal against dust, moisture, and other contaminants (IP rating protection), and often offering electromagnetic interference (EMI) shielding or explosion-proof capabilities in hazardous areas. These components ensure electrical safety, maintain system integrity, and protect against environmental damage in industrial installations.
Working Principle
Cable glands work by creating a compression seal around the cable jacket using internal components like sealing rings, compression nuts, and gland bodies. When tightened, these components compress against the cable, forming a watertight and dustproof barrier while mechanically locking the cable in place to prevent axial movement. The design typically includes a threaded entry for mounting to equipment and internal sealing elements that adapt to various cable diameters.
Materials
Common materials include brass (general purpose), stainless steel (corrosion-resistant), nickel-plated brass (enhanced durability), aluminum (lightweight), and plastic/nylon (non-metallic applications). Sealing elements are typically made from neoprene, silicone, or EPDM rubber for environmental sealing.

Frequently Asked Questions

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

While both terms are sometimes used interchangeably, cable glands specifically provide environmental sealing and strain relief, whereas cable connectors typically refer to devices that join cables electrically. Cable glands are mechanical fittings that don't conduct electricity.

How do I select the right cable gland for my application?

Consider cable diameter, thread size of the entry point, required IP rating, material compatibility with environment (corrosive, explosive), temperature range, and any certifications needed (ATEX, UL). Always match the gland to the smallest and largest cable diameters in your application.

Can cable glands be reused?

Most cable glands are designed for single use because sealing elements compress permanently. Reuse may compromise the seal. Some high-end glands with replaceable seals can be reused with new sealing components.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
