Rotary incremental Encoder (600 PPR - 5 :24V) AB 2 Phases 6mm Shaft

From the shop's description

This is an quadrature incremental rotary encoder YT06-OP with 600 PPR (pulse per revolution). The encoder outputs gray code which you can interpret using a microcontroller or Arduino 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 CNC machines, balancing robots and dead reckoning navigation. This encoder is of improved reliability with reverse connection and load short-circuit protection Features Resolution: 600 Pulse/Rotation Encoding Method: Incremental Input Voltage: 5 - 24VDC Maximum Rotating Speed: 6000rpm Cable Length: 50cm Shaft Diameter: 6mm To use with Arduino, need adaptor 9 VDC 1A.
