Nanotec encoders, 3-channel, are easy to mount and offer long-term reliability as well as high measurement accuracy combined with compact dimensions. They have high resolutions, are resistant to vibration acceleration and suitable for a wide temperature range. By comparing the demand/actual position they make it possible to run the motor in closed-loop mode and at the same time prevent mechanical overload or blocking. 

Please note:
An encoder with machine-friendly IP54 design is already integrated in the stepper and BLDC motors with increased protection class. They can also be used in harsh environmental conditions, and enable interference-free, fast and fault-free wiring.
