- ZMS Cable offers personalized cables : length, reinforced shield, special sheath (fireproof or high temperature), With technical support and fast delivery.
Product description
The KNX cable is a specialized bus cable in accordance with the ISO/IEC international standard 14543-3, mainly used for data transmission and control in home automation and buildings systems.
Its typical structure is 2x2x0.8 mm, comprising two pairs of twisted threads (Red/black and white/yellow) shielding, A copper driver of 0,8 mm in diameter and a PVC sheath.
This cable allows both the transmission of control signals and the power supply of connected devices. Thanks to its anti-interference design and effective armor, It ensures great signal stability, even in electrically noisy environments.
The KNX cable is ideal for connecting equipment such as lighting, air conditioning, Security or access control systems, allowing centralized and intelligent management of all the installations of a building. It supports transmission distances until 1000 meters, which makes it an essential infrastructure for networks of reliable and efficient intelligent buildings.
