Shielded halogen-free control cable – reliable data transmission

This flexible 225 V cable, designated RD-H(ST)H Bd 4x2x0.5, is an optimal solution for transmitting control signals and data in internal installations. Designed with safety and durability in mind, it is perfect for both building automation systems and industry. The shielded construction provides resistance to electromagnetic interference, guaranteeing stable and reliable communication.

### Construction and properties for professionals

The cable is distinguished by its careful construction, which translates into its unique properties. Multi-strand copper conductors (class 2) with a cross-section of 0.5 mm² provide good flexibility and ease of installation. Twisted pairs of conductors minimize interference, and an aluminum foil acts as a shield, protecting against external disturbances. Insulation made of a halogen-free polymer mixture increases safety – in the event of a fire, it limits the emission of toxic gases and smoke. The outer jacket made of the same material provides additional mechanical protection and resistance to weather conditions (indoors).

* **Halogen-free:** a key feature increasing fire safety – no release of toxic substances during combustion.

* **Shielding:** aluminum foil effectively suppresses electromagnetic interference, ensuring stable signal transmission.

* **Flexibility:** multi-strand conductor construction makes it easy to lay the cable even in tight spaces.

* **Temperature resistance:** the cable retains its properties over a wide temperature range – from -30°C to +70°C (after installation).

* **Compliance with standards:** meets the requirements of DIN VDE 0815 and the Low Voltage Directive 2014/35/EU (CE marking).

### Applications and benefits for everyone

This cable finds wide application in installations:

* **Control systems:** ideal for transmitting control signals in building and industrial automation.

* **Data transmission:** suitable for computer networks, alarm systems and monitoring.

* **Internal installations:** designed for permanent laying inside buildings (UV protection required for external installations).

* **Industry:** everywhere where reliable data and control signal transmission is required in an industrial environment.

Thanks to its properties, this cable guarantees not only reliable operation of the installation, but also increases the safety of users and minimizes the risk of failure caused by electromagnetic interference or fire. With an outer diameter of approximately 9 mm, it is easy to route and connect. Remember the minimum bending radius of approximately 7.5 x cable diameter to avoid damaging it during installation.
