Signal Cables - cables by the meter
Signal cables are designed for the reliable transmission of low-voltage signals, data, and information between devices. Our cables feature a tinned copper braid and are additionally shielded with a ferrite coating (EMC/COM). This effectively attenuates common-mode currents, making them particularly suitable for applications where common-mode interference or surface currents can cause problems. Our signal cables are therefore ideal for EMC applications.
In addition to their excellent electrical properties, signal cables are also characterized by high mechanical durability, making them ideal for use in demanding environments. Our signal cables are available by the meter.

Construction of the signal cables
Our EMC signal cables are available in a 6-core design. The conductors are made of tinned copper and insulated with PVC.
The insulated cores are fully enclosed by a tinned copper braid, which is additionally coated with a ferrite layer (EMC/COM) to provide enhanced electromagnetic shielding.
The outer sheath of the EMC cables is made of an orange-colored TMPU polyurethane compound (see schematic, not-to-scale design of the CMS cable).
CMS : 6-cores (white, brown, green, yellow, grey, pink): The cores are laid-up in concentric layers.

FAQ EMC cable
An EMC signal cable is a specially shielded cable designed for digital signal transmission in electromagnetically noisy environments. Its purpose is to minimize interference caused by electromagnetic fields while also preventing the cable itself from emitting interference. In addition, it effectively suppresses sheath currents. This ensures reliable and interference-free signal transmission. These CMS cables are used wherever common-mode interference or surface currents cause problems. They are widely used in automation, measurement, and communication technology, where high requirements for electromagnetic compatibility (EMC) must be met, e.g. in factory halls, where signals need to be transmitted over long distances.
Our customers describe this signal cable as the "problem-solving cable for EMC-related signal issues."
The EMC/COM ferrite coating applied to the cable is designed to reduce electromagnetic interference. The ferrite material increases the impedance to high-frequency interference signals and converts part of their energy into heat. As a result, unwanted interference is attenuated, while the desired signal remains virtually unaffected. Ferrite is particularly effective against common-mode interference, which propagates along the cable. This improves the electromagnetic compatibility (EMC) of equipment and prevents cables from acting as antennas for interference signals.
GNLM Cables
In GNLM cables, each individual conductor is coated with an EMC/COM ferrite layer and additionally shielded with an aluminum-polyester tape. This combination provides highly effective suppression of electromagnetic interference and ensures reliable signal transmission, even in environments with high electromagnetic noise.
CMS Cables
CMS cables feature a tinned copper braid shield coated with an EMC/COM ferrite layer. Unlike GNLM cables, this design encloses all conductors together. As a result, common-mode interference is effectively suppressed. Combined with the copper braid shield, the ferrite coating significantly improves electromagnetic compatibility (EMC) while substantially reducing the cable's susceptibility to interference
