Cable glands are mechanical devices used to securely attach and seal electrical cables to equipment, providing strain relief and environmental protection.
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.

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.
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.
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.
