Servo PUR cable for cable carriers acc. to UL/CSA TOPSERV® 121 PUR (4G1.5+2x(2x0.75)) mm² orange 700561

Flexible cable for cable carriers – reliability in servo applications

This specialized TOPSERV® 121 cable, with an outer diameter of 12.2 mm, is designed for use in cable carriers, particularly in servo systems. Its construction and materials guarantee high flexibility and durability, even with intensive bending and twisting. This cable combines power conductors (4x1.5 mm²) and control conductors (2x(2x0.75) mm²), making it an ideal solution where simultaneous power supply and control of devices are required.

Construction and properties for demanding applications

The cable is characterized by an advanced construction that ensures reliable operation in harsh industrial conditions. Copper strands, stranded according to DIN VDE 0295 cl. 6 and IEC 60228 cl. 6 standards, are insulated with halogen-free polypropylene, increasing user safety. Wire marking facilitates identification and connection of wires – Siemens, Lenze and universal color coding are available. A copper wire braid screen provides effective protection against electromagnetic interference (EMC), which is crucial in precise control systems. In addition, the outer jacket made of PUR (polyurethane) is resistant to abrasion, oils, hydrolysis and UV radiation – this guarantees a long service life even in an aggressive industrial environment.

Parameters and applications – from robotics to automation

The TOPSERV® 121 cable has been tested and certified according to UL AWM Style 21223/20234, CSA AWM and VDE standards. Its permissible operating temperature range is from -40°C to +80°C (flexible) and from -40°C to +90°C (stationary), allowing it to be used in a wide range of ambient temperatures. The rated voltage U is 1000 V, and the test voltage is 4000 V (50 Hz). This cable is primarily used in:

• Servo motors and encoders
• Robotics and industrial automation
• Machines and equipment requiring high precision
• Applications with frequent bending and twisting of cables (cable chains)
• Tool industry
• Where a combination of power and control conductors is required for braking or thermal protection functions.

Thanks to its construction and properties, this cable meets the stringent DESINA® standards, and its materials are free of silicone, cadmium and substances that interfere with painting. It is also resistant to cleaning with disinfectants compliant with ECOLAB®.
