Nidec Components 12V dc, 5 V dc 1024 ppr Pulse Optical Encoder with a 4 mm Plain Shaft, Panel Mount, Cable

The Copal Electronics optical rotary encoder belongs to RE30E series, It has 1024 resolution per revolution. It's operating principle is such as when the light from the LED which passes through the slit of the rotating disk actuates the photo-sensor. The output of the photo-sensor which is quasi-sinusoidal is shaped into square wave by the voltage comparator and fed into a logic circuit.

• Comes with a temp. compensation circuit
• It has zero index signal
• Operating temperature range is from 0 °C to 70 °C
• It has IP40 protection class
• Very economical
• It is RoHS compliant
