The CHA Hollow Shaft Servo Actuators Series are ideally suited for equipping with a single turn absolute measuring system that
can be connected directly to the actuator output.
The ECN 113 single turn absolute encoder is connected to the actuator flange by means of a torsionally stiff hollow shaft.
The encoder system is connected using a standard signal connector.
The evaluation of the compatibility of the measurement system must be checked
prior to commissioning. The measuring system contains electrostatically sensitive
components, please observe the ESD measures.
