Application

Both cables fulfill differing 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 conductors for the power supply to individual components are available. The braided shielding 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 jacket.
EMI = Electromagnetic Interference
To optimize the EMI features we recommend a large round contact of the copper braiding on both ends.

= The product is conformed with the EC Low-Voltage Directive 73/23/EEC and 93/68/EEC.

Properties

Special PUR outer jacket: low adhesion and flame retardant
Resistant to: oils and fats, acids and alkalis, hydraulic fluids, oxygen and ozone, UV-radiation, hydrolysis, microbial attack, water and weathering effects
The high abrasion resistance and notch resistance meet the highest requirements
The materials used in manufacture are cadmium-free, contain no silicone and are free from substances harmful to the wetting properties of lacquers
