Cable Clamps
for effective EMC grounding in cabinets
Cable clamps are used to connect cable shields to ground and thus reduce electromagnetic interference in cabinets and industrial installations.
The correct cable clamp ensures low impedance, stable EMC performance and service-friendly installation.

FAQ – Frequently Asked Questions about Cable Clamps
How do I choose the right cable clamp for my installation?
The choice of cable clamp is governed by the cable type, the structure of the shield and how the installation is to be mounted in the control cabinet.
Pay particular attention to:
- Cable diameter and screen type – braided or foil screen
- Mounting – DIN rail, mounting plate or directly on ground point
- Contact pressure – crucial for low transition impedance
- Service and access – important for re-tightening and maintenance
The right cable clamp provides consistent EMC protection and reduces the risk of interference in control and signal cables.
When are other solutions more appropriate?
Shield clamps are not always the right choice in all applications.
Alternative solutions may be more suitable:
- When grounding several protective earths together, grounding bars are used.
- For flexible connections or vibrations, grounding braids are used.
For tight cable entry with EMC requirements, EMC cable glands may be a better choice
What is the difference between cable clamp and grounding braid?
Shield clamps are used for direct connection of cable shields, while grounding braids are used for flexible grounding between components.
Which shield clamp should be used for braided cable shield?
Braided cable shields require even and sufficiently high contact pressure to ensure good ground connection.
Shield clamps for braided shields provide stable mechanical fixation and good electrical contact around the entire cable shield, making them a common solution in industrial control cabinets.
How do screen clamps differ for foil screens?
Foil screens are more sensitive than braided screens and therefore require clamps that do not damage or deform the screen.
These clamps provide customized contact pressure and are often used in signal and data cables, where correct EMC grounding is important for stable communication.
Where should cable clamps be mounted in the cabinet?
They are normally mounted close to the cable entry to divert interference as early as possible.
Can multiple cables be connected to the same cable clamp?
It depends on the design of the clamp. Only use solutions designed for multiple cables.
Do cabel clamps need maintenance?
When rewiring or servicing, the contact point should be checked to ensure a good connection.
