The DMX30 and DMX50 cables are designed for digital signal transmission according to the DMX and AES-EBU standards. These are the most important standards for professional on stage and broadcast use in the field of audio and video, requiring balanced cable connections with a characteristic impedance of 110 Ohm. The DMX30 is a cable for digital signal transmission with a characteristic impedance of 110 Ohm, consisting of two conductors with a section of 0.23 mm², while the DMX50 cable consists of four conductors with a section of 0.12 mm². They are both surrounded with an Aluminum foil and braiding, ensuring the best shielding of the cable, resulting in an excellent protection against interference of all kinds of electromagnetic fields, produced by dimmers, electric motors, power cables and many other electromagnetic interference sources.

The 110Ω cables ensure a reliable digital signal link. Especially made for the transmission of DMX lighting control signals or AES signals for the exchange of digital audio signals between professional audio devices.
Tin is a useful plating for copper because it not only helps to boost copper’s properties, it also helps the wire to last much longer and counter acts against oxidation. Tin also helps to strengthen the copper wire, making it more resilient to breakage or lost connections, at the same time boosting the coppers conductivity.
For ease of installation these bulk cables are provided with an indication on every meter of the cable. This enables installers to have a clear and efficient indication of how many meters they still have available on their reel.
Tinned copper braid shielding provides superior physical protection, while maintaining good flexibility and flex life. These shields are the ideal choice for minimizing interference and have lower dc resistance than foil. The tin plating also adds to the copper in the cable as it not only helps to boost the copper’s properties, it also helps the wire to last much longer and counter acts against oxidation.
Aluminum foil shielding is ideal for reflecting electromagnetic interference (EMI) and is often used in combination with a braided wire to absorb EMI.
