Cable Glands

Cable glands, also known as cable connectors, stuffing glands or cable fittings, are mechanical devices used to securely attach and seal cables to equipment, enclosures, or surfaces while providing protection against environmental factors such as dust, moisture, and even the entry of gases or liquids. They are commonly used in various industries, including electrical, telecommunications, manufacturing, and construction.

Cable glands come in various sizes, materials, and designs to accommodate different cable types. They often consist of multiple components, including a body, a sealing element (such as a rubber or elastomeric seal), a locknut, and sometimes additional features like gaskets or washers. They are commonly used alongside Cable Gland Adaptors and Cable Gland Plugs.

A wide range of brands are available, such as RS Pro, LAPP, Peppers, Molex, Entrelec, Kopex-EX, ABB, and many more, for versatility and compatibility.

What are cable glands used for?

Cable Protection: Cable glands provide strain relief, which prevents cables from being pulled or twisted at the point of entry into equipment. This helps to protect the cables from damage and ensures longevity.
Environmental Sealing: Cable glands typically have features that allow for effective sealing against external elements. They prevent dust, dirt, water, and other contaminants from entering into the equipment or enclosure, thereby safeguarding the components inside.
Safety: Cable glands can help prevent dangerous situations such as electrical shorts or fires by providing a secure and proper connection between cables and equipment.
Cable Management: Cable glands help organize and manage cables, keeping them neat and well-arranged within enclosures or equipment.

What are the different types of cable glands?

Metal glands - suitable for use in more demanding environments. The glands are robust and can cope with the high demands of harsher environments. Metal glands include brass, stainless steel, SWA and nickel-plated.
Plastic glands - Due to their clamp and seal design, plastic glands have a wider cable entry range. They are ideal for flexible cables and provide high strain relief. Plastic glands include polyamide and nylon.
Ingress protection - The IP rating can also be a key feature to consider when selecting a cable gland. IP-rated glands offer extra protection to reduce the ingress of dust and moisture. Protection classes range from IP44 to IP69K. The most popular is IP67 or IP68.
Hazardous kits - are for fitting onto cables in dangerous or high-risk enclosures. This includes ATEX and HL3 cable glands, which perform in explosive, flammable or combustible atmospheres.
