Description Resolution: 200 Pulse/Rotation Input Voltage: 5 - 12VDC Maximum Rotating Speed: 5000rpmThis Rotary Encoder - 200 P/R (Quadrature) 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. The encoder comes with a set screw coupler which will attach to any 4mm shaft.View moreDimensionsLinksPDF File Rotary Encoder - 200 P/R (Quadrature) DatasheetSpecifications Allowable Radial Load: 5N Allowable Axial Load: 3N Cable Length: 50cm Shaft Diameter: 4mm
