Cable Glands
for safe cable entry in industrial installations
Cable glands are used to introduce, seal and relieve cables in control cabinets and enclosures. The right choice affects the enclosure class, EMC performance and the long-term reliability of the installation.
Here you will get an overview of different types of cable glands and when each solution is right.
Explore our range of cable glands
Cable glands in polyamide for secure cable entry, sealing and strain relief in control cabinets and electrical installations.
A flexible choice for automation, machines and control systems.
EMC cable glands for secure shielding in interference-sensitive installations.
Provides effective 360° contact for good EMC performance and quick installation.
Complementary accessories such as lock nuts, seals, O-rings, plugs, adapters and relief bends.
The right accessories improve sealing, strain relief and serviceability.
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.
Important requirements & common pitfalls
This is where many installations go wrong:
- wrong material in aggressive environment (corrosion)
- Insufficient EMC contact despite shielded cable
- too low IP class for outdoor installation
- too narrow dimensioning which makes future cable replacements difficult
If in doubt: Contact C-PRO for technical advice before making a choice.
Different types of cable glands
Plastic cable glands
For standard environments in industry and automation where low weight and good chemical resistance are important.
Metal cable glands
For applications with high mechanical load, vibration or where metal enclosures are used.
EMC cable glands
The cable shield must be connected correctly to ensure EMC performance in interference-sensitive installations.
ATEX-rated cable glands
For use in explosive environments where both mechanics and sealing are safety-critical.
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.
Related product areas
Cable glands are often only part of the solution.
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.
➡ Enclosures & enclosures – The choice of cable gland must always match the enclosure material, material thickness and IP requirements.

FAQ - Frequently asked questions about cable glands
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 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.
