ELTRA Incremental Rotary Encoders

An incremental rotary  encoder ELTRA can be used in positioning and motor speed feedback applications which includes servo/light-, industrial- or heavy-duty applications.
An incremental encoder ELTRA provides excellent speed and distance feedback and, since there are few sensors involved, the systems are both simple and inexpensive. An incremental encoder ELTRA is limited by only providing change information, so the encoder requires a reference device to calculate motion.
Encoders ELTRA are designed in order to control the position and the angular speed of moving mechanical axels.
Main application field of incremental optical encoders are: wood-working machinery, textile machines, CNC machinery, and so forth.
ELTRA brand encoders offers a complete range of incremental encoders with resolution up to 10.000 pulses per turn (ppr) with a wide flange choice and several electronic outputs.
Shaft, blind hollow shaft and through hollow shaft up to a diameter of 75 mm (2.95") are available.
An incremental encoder output is cyclical when the encoder is rotated.
Eltra offers hollow shaft rotary encoders, solid shaft rotary optical encoders and magnetic incremental encoders.
