LON-BUS cable H122 FRNC 1x2XAWG22/1 for fixed installations 802187

LON-BUS cable for building automation systems

This LON-BUS H122 FRNC cable is designed for fixed installations in building automation systems utilizing the LON BUS (Local Operating Network) bus. The LON BUS system enables the transmission of various data, making it a versatile solution in modern buildings. This cable complies with DIN EN 50090-2-2 (VDE 0892 part 2-2:1997-06), guaranteeing its reliability and safety.

Construction and application

The cable is characterized by a 1x2xAWG 22/1 construction, which means a single core with two AWG 22/1 wires. Made of tinned copper (AWG 16/19) and insulated with PE foam and PVC, it provides good conductivity and durability. The white FRNC (halogen-free) outer coating increases safety in the event of a fire, minimizing the emission of toxic gases. This cable is ideal for permanent laying inside buildings where reliable data transmission in automation systems is required.

Key features and parameters

The LON-BUS H122 FRNC cable stands out from other solutions thanks to several important properties: a wire cross-section of 0.32 mm² provides adequate current carrying capacity for LON BUS applications, and an outer diameter of approximately 4.4 mm facilitates cable routing in installations. The cable maintains its properties over a wide temperature range from -20°C to +75°C (during fixed installation). An impedance of 100 Ohm ± 10% is important for correct signal transmission, and a wire resistance of a maximum of 57 Ohm/km affects the efficiency of data transmission. Mutual capacitance up to 45 nF/km helps minimize signal interference, and a working voltage of 125 V ensures safe system operation. The cable weight is approximately 25 kg/km, which facilitates transport and assembly. Additionally, the presence of an AL foil as a shield minimizes electromagnetic interference affecting signal quality.
