    Microbial attack
    Water and weathering effects
  • The high abrasion resistance and notch
    resistance meet the highest requirements
  • The materials used during manufacturing
    are cadmium-free, contain no silicone
    and are free from substances harmful
    to the wetting properties of lacquers
Note
  • For extreme applications extending beyond
    standard solutions we recommend that
    you request our questionnaire, which has
    been especially designed for energy supply
    systems.
  • Please observe the assembly instruction
    for use in energy supply chains.
  • AWG sizes are approximate equivalent
    values. The actual cross section is in mm².
Application
Both cables fulfil different tasks for the control of servo-motors. The tachofeedback-cable or response cable serves the regulation of the motor speed and measurement of the actual values. The incremental feedback-cable or position response cable transfers the control signals for positioning and engineering characteristics and is used as the flexible connecting cable for tachometer, brakes and pulse transmitter in case of high mechanical stress in plant, machine and control engineering in dry, moist and wet rooms. Particularly suitable for continuous operating in drag chains, industrial robotics and handling equipment as these cables enable an excellent transmission of data and signals. Additional cores for the power supply to individual components are available. The braided screen guarantees reliable signal transmission. Optimum functionality, long service life and an excellent cost-performance ratio are given for the mentioned applications by the special compounds used for insulation and sheath.
EMC = Electromagnetic compatibility
To optimize the EMC features we recommend a large round contact of the copper braiding on both ends.
CE = Product conforms with Low-Voltage Directive 2014/35/EU.
