Control cable BiT 500 2(St) 7x2x2.5 SB0561

Control cable for demanding applications

BiT 500 2(St) 7x2x2.5 control cable is a reliable solution for internal electrical installations where flexibility and resistance to interference are required. The construction with double shielding – aluminum foil on strands and an overall screen – minimizes the risk of electromagnetic interference, which is crucial in control and automation systems. Numbered cores facilitate identification and connection, and the flexible construction ensures comfortable work during installation in tight spaces.

Construction and application

This cable is characterized by a construction based on seven strands, each containing two cores with a cross-section of 2.5 mm². Made of copper, with insulation made of polyvinyl chloride (PVC), it provides good electrical and mechanical insulation. Aluminum foil shielding and an earthing conductor increase safety and protect against interference. The BiT 500 2(St) cable is intended for use in dry and damp indoor environments, and is ideal for building installations, machines and equipment.

Key features and benefits

• Double shielding: Aluminum foil on strands and an overall screen provide high resistance to electromagnetic interference, guaranteeing stable operation of control systems.
• Flexible construction: Facilitates installation in tight spaces and minimizes the risk of damage to the cores during installation.
• Numbered cores: Simplify identification and connection of wires, saving time and reducing the risk of errors.
• Temperature resistance: Permissible operating temperature range from -40°C to +80°C allows the cable to be used in various environmental conditions.
• Compliance with standards: Meets the requirements for fire resistance according to IEC 60332-1-2, which increases safety.
• Mechanical strength: Made of high-quality materials ensures long-lasting and reliable operation.
• Core cross-section: 2.5 mm² provides adequate current carrying capacity for most control applications.
• Round shape: Facilitates cable routing in installations.

Technical parameters in practice

Core resistance of 7.98 Ω/km affects the minimum voltage drop on the cable, which is important for longer lengths of control cables. The minimum bending radius of 100 mm (fixed installations) and 200 mm (mobile installations) allows for flexible cable routing without the risk of damage to the cores. Fire reaction class Eca indicates the limited flammability of the outer jacket material, which increases the fire safety of the installation.
