What is a waterproof cable gland?
Cable glands can have different protection classes and be waterproof, for example. Cable glands that are waterproof are suitable for areas of application where moisture plays a role. This is the case for outdoor applications, among others.
How is a waterproof cable gland structured?
Waterproof cable glands - their structure hardly differs at all from that of other cable glands. Two housing parts and a sealing ring are elementary components. In addition, a locking nut is part of the cable gland.
Waterproof cable glands can have numerous other properties. These include tension relief, which ensures that cables do not come loose from the connector, kink protection, permanent vibration protection or variable clamping ranges.
Properties of waterproof cable glands
Waterproof cable glands differ in terms of their manufacturing material. The following variants in particular are typical:
- waterproof cable gland made of plastic
- waterproof cable gland made of stainless steel
- water proof cable gland made of brass
Plastic glands are primarily made of polyamide, or PA for short. PA stands out thanks to its robustness and, depending on the composition, with advantages such as UV resistance, chemical resistance and application options in a wide temperature range.
Stainless steel cable glands feature characteristics such as weather, corrosion and temperature resistance as well as durability.
However cable glands made of brass can also often be used in wide temperature ranges and are ideal for use in changeable weather conditions. Brass waterproof cable glands are also available in an electromagnetically compatible form.
Protection types of waterproof cable glands
Like all other cable glands, waterproof cable glands are available with different protection classes, designated for example as IP65, IP68 or IP69. IP protection classes provide information on the extent to which electrical equipment is suitable for use in a particular environment. Waterproof cable glands are available with the following protection classes:
- IP65 – dust-tight, protection against jets of water regardless of the direction they are coming from
- IP66 – dust-tight, protection against heavy jets of water and in the event of short-term flooding
- IP67 – dust-tight, protection in the event of temporary submersion for up to 30 minutes
- IP68 – dust-tight, protection against permanent immersion
- IP69 – dust-tight, protection against water with high pressure, e.g. from high-pressure cleaners
Lower protection classes only provide protection against dripping, spraying or splashing water and are therefore not suitable for long-term use in damp and wet environments.
