These transducers have been designedly developed by ELCIS for uses that simultaneously or alternatively require the information form two incremental encoders set in a same container. 

The separated photo-electric detections on two different tracks, the double amplifiers galvanically separated, allow to the user of these encoders a large variety of appliances, among which: the measure - conversion from metric into imperial (particularly used in the British country), the mounting on the electrospindles for the C axis control with a high resolution detection (max 90000 div) and low spindle revolutions and second detection with middle resolution (1000÷2500 div) and high spindle revolutions.

The number of pulses/rev. is from minimum of 1 up to a maximum of 90000 (in according to those available for each model).
