ELTRA Rotary Incremental Encoders

 
    Rotary encoders are electro-mechanical devices designed to control the position and the angular speed of mechanical axles in motion.
Rotary incremental encoders are so defined since they track the increase (variation) in respect to a position taken as a reference point and independently from the direction of the rotation. The incremental encoder senses rotation, speed and acceleration by counting the number of pulses sent by the output circuit, but the zero point must be reset at every new start.

    Eltra has developed a broad catalog of incremental encoders here classified according to the type of mechanical mounting (solid vs blind/though hollow shaft) and the type of sensing technology (optical vs magnetic), with a wide range of resolution, flange and electronic outputs available to meet the specific application's needs.
Besides standard versions, Eltra offers to its Customers the possibility to customize and even develop custom-tailored devices in order to satisfy also the most peculiar requests and to provide 360° solutions.
