A cable gland, also known as a cable connector or fitting, is a device designed to attach and secure the end of an electrical cable to the equipment. It provides strain relief, grounding, and environmental protection.

Common types include:

• Threaded glands: Provide secure connections through threaded fittings.
• Compression glands: Use a compression mechanism to secure the cable.
• Sealing glands: Offer environmental protection by sealing the cable entry point.
• Explosion-proof glands: Designed for hazardous environments to prevent sparks.
• EMC glands: Provide electromagnetic compatibility shielding.

The right size depends on the cable diameter and the entry hole size. Manufacturers provide sizing charts that match the cable gland to the cable’s outer diameter. It’s important to measure the cable accurately and choose a gland that fits snugly without over-compression.

The IP (Ingress Protection) rating indicates the level of protection the gland provides against solids and liquids. For example, an IP68 rating means the gland is dust-tight and can withstand continuous immersion in water. The rating helps determine the suitability of the gland for specific environments.

Generally, cable glands are not intended to be reused, especially compression types that deform during installation. However, some metal cable glands can be reused if they are carefully removed and inspected for damage.
