EMC Cable Entry System
for safe cable entry into control cabinets
EMC cable glands are used to introduce cables into control cabinets without impairing shielding or grounding.
Proper EMC bushing ensures low transition impedance and contributes to stable EMC performance in industrial installations.

Choose the right EMC cable gland for your installation
The choice of EMC cable gland is governed by the cable type, enclosure requirements and which EMC levels the installation must meet.
Based on:
- Cable version – with or without contact
- Display connection – 360° shield contact to housing
- Enclosure class – IP requirements when cleaning or outdoors
- Mounting – hole-making, sheet metal or frame mounting
A correctly selected EMC bushing stops interference at the cable entry point and reduces the need for subsequent measures.
EMC cable glands for various cable types
EMC bushings for cables without contact
For unspliced cables, EMC bushings with direct shield connection provide high EMC performance.
Characteristics:
- Continuous 360° screen contact
- Low transition impedance
- Suitable for control, signal and motor cables
EMC cable entry frames with connector
When cables cannot be cut, EMC frames are used that enable shielded cable entry while maintaining contact.
Characteristics:
- Flexible cabling
- Sealing and shielding in the same solution
- Common solution in control cabinets and automation systems
EMC performance and grounding in control cabinets
EMC cable glands act as a first barrier against electromagnetic interference. By connecting the cable shield directly to the enclosure, interference is conducted away before it affects internal components.
Correctly performed EMC insertion contributes to:
- Reduced emissions
- Improved immunity
- Stable and reproducible function
When might other solutions be more appropriate?
EMC cable glands are not always necessary in all installations.
Alternatives may be more suitable:
- For low EMC requirements, standard cable glands may be sufficient
- Shield clamps are often used for shield connection inside the cabinet.
- For flexible grounding between parts, grounding braids are used.
FAQ - Frequently asked questions about EMC cable glands
What distinguishes an EMC cable gland from a standard gland?
EMC bushings provide electrical contact between the cable shield and the housing, not just mechanical sealing.
Do all shielded cables need EMC cable glands?
No, the need depends on EMC requirements, frequency levels and the sensitivity of the installation.
Do EMC bushings affect the enclosure class?
They are designed to maintain enclosure class when mounted correctly.
Can EMC penetrations be combined with other EMC measures?
Yes, they are often used together with shield clamps and proper potential equalization.
