Control cable BiT 500 BLACK OR 7x0.75 SB2139

Universal control cable for demanding applications

This 7-core BiT 500 BLACK OR cable with a cross-section of 0.75 mm² is a robust solution for both professional installers and end users. Designed for operation under harsh conditions, it delivers reliability and safety across a wide range of applications. High flexibility is ensured by its class 5 multi-wire conductor construction, facilitating easy installation and routing in confined spaces.

Construction and properties

The cable features copper conductors insulated with PVC, surrounded by an outer black PVC sheath. This construction provides resistance to moisture, UV radiation, and oils, enabling use both indoors and outdoors—including direct burial in soil. The cable is flame-retardant (compliant with IEC 60332-1-2 and IEC 60332-3-24 Cat. C) and does not propagate flame on a single cable. Conductors are black and numbered for easy identification, with an additional yellow-green conductor serving as the protective earth. Conductor resistance is 26 Ω/km.

Applications and benefits

The BiT 500 BLACK OR cable performs excellently in control installations, powering automation devices, industrial machinery, and monitoring systems. Its wide operating temperature range of -40°C to +80°C enables use in extreme environments. Oil resistance makes it ideal for mechanical workshops and production halls. Rated voltage of 300/500V ensures compatibility with most control devices. Minimum bending radius is 92 mm for mobile installations and 46 mm for fixed installations, simplifying routing in various configurations. Fire reaction class Fca provides enhanced safety during use.
