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, pulse transmitter in system and mechanical engineering, in dry, damp and wet environments.
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.
