Important requirements & common pitfalls
This is where many installations go wrong:
⚠ Material failure in aggressive environment (corrosion)
⚠ Material failure in aggressive environment (corrosion)
⚠ Insufficient EMC contact despite shielded cable
⚠ Too low IP rating for outdoor installation
⚠ Tight sizing that complicates future cable replacements
If in doubt: Contact C-PRO for technical advice before making a choice.

Depending on cable type, installation and service requirements, other product areas may be more suitable or serve as a complement.
Cable glands & cable gland frames → For installations where cables are contacted or where many cables must be inserted into a small area.
EMC products for grounding and shielding → When proper shield connection and low transition impedance are crucial for the EMC performance of the system.
Cabinets & enclosures → The choice of cable gland must always match the enclosure material, material thickness and IP requirements.
FAQ - Frequently asked questions about cable glands
When are cable glands used?
Cable glands are used when cables are to be introduced into control cabinets, junction boxes or enclosures and at the same time require:
- sealing against dust and moisture (IP class)
- strain relief
- mechanical protection
- sometimes also EMC shielding
The choice is guided by environment, cable type, mobility and future service requirements.
When are cable glands not the right solution?
Cable glands are not the right choice when:
- cables are already connected and cannot be dismantled
- many cables must be inserted into a very limited area
- sealing and strain relief must be solved modularly
In these cases, it is often ➡ cable entry frames or divisible systems a better alternative.
What types of cable glands are there?
There are several types of cable glands depending on the material, environment and technical requirements. Common variants are:
- plastic cable glands
- metal cable glands
- EMC cable glands
- ATEX-rated cable glands
The choice depends on the installation's requirements for mechanical strength, sealing, EMC protection and environment.
Which material should I choose – plastic or metal?
Plastic (polyamide) is lightweight and affordable for standard environments. Metal provides high strength and is suitable for tougher environments and outdoors.
When are metal cable glands a better choice?
Metal cable glands are used when the installation is exposed to higher mechanical loads, vibrations or where the enclosure is made of metal.
They provide high mechanical strength and are often used in machines, industrial plants and installations where extra robust cable entry is required.
When is EMC gland needed?
For interference-sensitive electronics, such as control systems and communications. EMC glands provide shielding and stable operation.
Which IP class should I choose?
Consider the environment. IP68 is submersible, IP69K is high-pressure water resistant. See also our guide to IP ratings.
