Rotary Encoder - 1024 P/R (Quadrature)

This 1024 pulse per rotation rotary encoder outputs [gray code]( which you can interpret using a microcontroller and find out which direction the shaft is turning and by how much. This allows you to add feedback to motor control systems. Encoders of this kind are often used in balancing robots and dead reckoning navigation but it could also be used as a very precise input knob.


* Resolution: 1024 Pulse/Rotation
* Input Voltage: 5 - 12VDC
* Maximum Rotating Speed: 6000rpm
* Allowable Radial Load: 5N
* Allowable Axial Load: 3N
* Cable Length: 50cm
* Shaft Diameter: 6mm
