Motor Feedback

Devices for electric motors of any kind and size

The motor feedback industry comprehends many technologies applied to a large variety of markets: from elevating systems to material handling, from the manufacturing to the iron and steel industry, the motor is the heart of any mechanism in motion. For this reason it’s necessary that each and every of its components shall be extremely robust, solid and, at the same time, accurate and effective for its employment.


In accordance with the requirements of the drive technology industry, Eltra offers several lines of incremental and absolute encoders, designed to be very adaptable and efficient both in terms of technical features, providing a wide choice of resolutions and mounting systems, suitable for several types and sizes of shafts and motors, that in terms of costs, by offering solutions with a very interesting price/quality ratio.
