Building Automation & Control

About Building Automation & Control

This category holds control and signal cables for building management, automation and instrumentation, grouped by application: BMS, KNX and bus cables for building control networks; PLC, automation and control cables for panels and field devices; instrumentation and sensor cables for measurement signals; thermostat cables for HVAC controls; and general multi-conductor cables.

Most families are offered in both unshielded and shielded constructions; shielded versions are the usual choice for signal circuits routed near power cabling. Core count and conductor size are listed on each model page. See the ELV & Automation overview, or contact our technical support team for help matching a cable to a control system.

Cables by type

Multi-conductor (39) · instrumentation (32) · control (24) · automation (24) · PLC (24) · BMS (21) · sensor (18) · bus (15) · thermostat (12) · KNX (6)

How to choose

Start from the system protocol. BMS and bus networks (such as RS-485, Modbus or BACnet MS/TP) use shielded twisted pairs. KNX uses its own certified bus cable. Control and multi-conductor cables run from 2 to 24 cores, and instrumentation cables come in 1 to 16 pairs, foil or foil-and-braid shielded where signals must be protected from noise.

FAQ

What is BMS cable? Shielded twisted-pair cable that links building management controllers, sensors and field devices.

Can I use Cat6 for BMS? Only where the device maker allows it; RS-485 and similar buses are specified for shielded twisted-pair cable with the right impedance.
