Halogen-free control and power cable, shielded HELUCONTROL® OZ-520-HMH-C LS0H GREY 2x0.5 mm² grey, black numbered cores according to DIN VDE 0293-334 11008758

Halogen-free control cable – safety and reliability in one

This flexible control cable, designated JZ-520 HMH-C LS0H, is a solution designed for demanding applications where fire safety and reliable signal transmission are crucial. The cable is characterized by high flame resistance and limited emission of smoke and toxic gases during combustion, making it an ideal choice for public and industrial buildings.

Construction and properties

The cable has been designed with the latest safety standards in mind. Its construction is based on copper conductors, which provide good electrical conductivity. These conductors are insulated with halogen-free TI7 polymer, which minimizes the risk of toxic substances forming in the event of a fire. In addition, the cable has a screen in the form of a braid of copper wires, which effectively protects against electromagnetic interference (EMC). The outer sheath made of halogen-free M1 plastic provides additional protection and resistance to mechanical damage.

A key feature of this cable is its CPR class B2ca-s1a, d0, a1 – this demonstrates its high reaction to fire and low level of smoke and corrosive gas emission. This means the cable meets the stringent fire safety requirements for public buildings.

Application and benefits

The JZ-520 HMH-C LS0H cable is widely used in control installations in places with increased fire safety requirements, such as:

• Office buildings and skyscrapers
• Hospitals and medical facilities
• Educational and cultural institutions
• Airports and railway stations
• Subways
• Industrial installations (production lines, conveyor belts)
• Air conditioning and ventilation systems

Why choose this cable?

• Safety: Halogen-free construction minimizes the risk of poisoning by toxic gases during a fire.
• Protection against interference: A screen made of copper braid ensures stable signal transmission in environments exposed to electromagnetic interference.
• Durability: High-quality materials guarantee long-lasting reliability even in harsh operating conditions.
• Compliance with standards: Meets the requirements of DIN VDE and EN standards, confirming its high quality and safety.
• Flexibility: Allows easy installation and adaptation to various installation configurations.
• Wide operating temperature range: Possibility of use in both stationary (-40°C to +70°C) and flexible (-15°C to +70°C) temperatures.

Remember to optimize EMC by ensuring two-sided contact of the copper braid with the terminals (e.g. EMC cable glands). The product complies with the Low Voltage Directive 2014/35/EU (CE marking).
