Balanced signal cable - flex 0.20 mm² - 24 AWG - EN50399 CPR Euroclass Cca-s1b,d1,a1

The CSB224-CCA is a high quality stereo balanced signal cable compliant to Cca standards of the Construction products regulations (CPR) regarding fire and flammability resistance in fixed installations, minimizing toxic smokes and providing optimal resistance to spreading fire.

In addition to its improved fire properties, the outer jacket of the cabling is smooth and durable for easy installation and pulling. The conductor section consists of two individually jacketed pairs which are surrounded by one outer jacket, allowing stereo balanced signal transfer over one single cable. Each individual pair consists of a 24 AWG stranded conductor with an aluminum foil shielding and drain wire. The highly effective shielding offers excellent immunity against noise and interference caused by external devices. The stranding keeps the cable flexible and easy to handle.
