Control cable UNITRONIC LiYY 4x0.25 0028304

UNITRONIC LiYY 4x0.25 cable is a flexible control cable designed for use in dry and humid environments, both indoors and outdoors – provided it is protected from UV radiation. Manufactured by the renowned Lapp Kabel, it ensures reliable connections in control, automation systems and electrical installations.

Construction and application

The cable features a construction with copper conductors with a cross-section of 0.25 mm², insulated with polyvinyl chloride (PVC). The conductors are twisted together, forming a bundle without shielding. The whole is surrounded by an outer PVC coating, providing mechanical protection and resistance to external factors. This makes the cable perfect for applications requiring flexibility and abrasion resistance. It is ideal for connections in machines and equipment where cables are exposed to movement and bending.

Advantages and product features

• Flexibility: Multi-wire conductor construction (class 5) provides high flexibility, making it easy to lay and connect the cable even in tight spaces.
• Resistance: The outer PVC coating protects against moisture, oils and mechanical influences.
• Identification: Color-coded conductors facilitate correct connection and minimize the risk of errors during installation.
• Safety: Fire reaction class Eca meets European fire safety standards.
• Versatility: The cable is suitable for both fixed (permissible temperature from -40°C to 80°C) and moving (permissible temperature from -5°C to 70°C) installations.
• Space saving: Small outer diameter (4.3 mm) allows more cables to be routed in a limited space.
• Rated voltage: The cable is designed to operate at a rated voltage of 50 V.

User parameters and installation

The minimum bending radius during fixed installation is 17.2 mm, and in moving installations without guidance – 43 mm. It is important to maintain these values to avoid damage to the conductors and ensure long-term connection reliability. The cable is designed to operate at temperatures from -5°C to +70°C during installation and from -40°C to +80°C after installation (without vibration). It is worth noting the lack of shielding – the cable is not intended for applications requiring protection against electromagnetic interference.
