Atex / Ex cable connectors

ATEX cable glands - The glands for potentially explosive environments

Cable glands are used on electrical and mechanical equipment used in a potentially explosive environment. An Ex cable gland prevents the formation of sparks (sparking), withstands explosion pressure or has increased dust tightness. Our range includes cable glandsmade of polyamide, brass and stainless steel.

What is an ATEX / Ex cable gland?

An ATEX cable gland is designed for use in areas with an increased risk of explosion. Depending on the version, an Ex cable gland fulfils different requirements.

A cable gland with the abbreviationEx d features a pressure-resistant enclosure that can withstand an explosion, e.g. in a control cabinet or a housing.

In comparison. an EX e cable gland prevents sparking and arcing. This reliably prevents the ignition of explosive gases, for example.

Compared to the above-mentioned models, an ATEX cable gland of the Ex t type fulfils a sealing function, as it reliably prevents the penetration of dust particles into machine housings, as well as electrical systems and control cabinets.

But regardless of whether you are using an Ex cable gland from WISKA or a Lapp cable gland: Models that meet the ATEX ( ATmosphères EXplosibles) requirements are similar in terms of functionality. In addition to the sealing function, cable glands are also used for electrical insulation, to protect against cable kinks / breaks or for tension relief of the cables. A cable gland with ATEX certification usually can be easily recognised thanks to its appearance - a blue cap nut in RAL5012.

Where is an Ex cable gland required?

A cable gland for the Ex area is often used where flammable substances such as solvents, paints or fuel are used or produced.

Ex cable glands are required wherever electrical equipment has an increased explosion risk and must be protected accordingly. These include the pharmaceutical, refinery and food industries, but also industries in which wood and metals are processed. ATEX cable glands are subject to the ATEX operating directive or standard 1999/92/EC.

Materials of an ATEX / Ex cable gland

An ATEX cable gland is usually made of metal or plastic where the connector is usually made of brass or polyamide and the seal of silicone. Ex cable glands in stainless steel are also available. The ATEX cable gland made of stainless steel is characterised above all by its corrosion resistance.

Properties of an ATEX / Ex cable gland

One of the main properties of an ATEX cable gland is that it is pressure-resistant to rapidly spreading explosive gases. Furthermore, the Ex e cable gland is characterised by its electromagnetic compatibility. To make installation quick and easy, there are also splittable Ex cable glands that considerably reduce the effort involved in installation.
