Servo PUR cable for cable carriers acc. to UL/CSA TOPSERV® 109 PUR (4G4) mm² orange 75945

Flexible cable for servo drives – reliability and durability in demanding applications

This specialized cable, catalog number 75945, is designed for operation in cable carriers and is characterized by exceptional flexibility thanks to its construction based on multi-wire strands of class 6. Made of polyurethane (PUR), it is resistant to abrasion, oils, hydrolysis and UV radiation, making it an ideal solution for applications in robotics, tooling industry and other demanding industrial environments. This cable complies with UL AWM Style 21223 and 20234 standards and has CSA AWM and VDE certifications.

Construction and properties

The TOPSERV 109 4x4 cable consists of four copper conductors with a cross-section of 4 mm², insulated with halogen-free polypropylene. The conductors are marked in accordance with Siemens, Lenze and general European standards, which facilitates identification and connection. An additional copper braid screen provides protection against electromagnetic interference (EMC) and increases resistance to mechanical damage. The outer jacket made of PUR guarantees high durability and resistance to external factors.

• Flexibility: Class 6 stranded construction provides high flexibility, making it easy to lay the cable in tight spaces and dynamic applications.
• Safety: Halogen-free polypropylene insulation minimizes the emission of toxic gases in the event of a fire, increasing the safety of the installation and personnel.
• Resistance: PUR jacket provides resistance to abrasion, oils, hydrolysis, UV radiation and chemicals, extending the cable life even in harsh working conditions.
• Shielding: Copper braid effectively protects against electromagnetic interference, ensuring stable signal transmission.
• Wide temperature range: The cable retains its properties over a wide temperature range – from -40°C to +80°C (stationary operation up to +90°C), allowing its use in various environmental conditions.

Applications and compatibility

The TOPSERV 109 4x4 cable is designed to connect power conductors with control conductors in servo motors and other devices requiring a reliable electrical connection. It will perform perfectly where a simultaneous braking and thermal protection function is needed. It is compatible with Siemens, Lenze and Bosch Rexroth control systems. Due to its mechanical and electrical properties, it finds application in:

• Industrial robotics
• Automation
• Machines and production equipment
• Control drives
• Cable chains (in accordance with installation rules)
• Applications requiring high durability and reliability of electrical connections
