Incremental Photoelectric Rotary Encoder 400P/R

This is an industrial incremental photoelectric rotary encoder from DFRobot. It generates a two-phase orthogonal AB pulse signal through the rotation of the grid disc and the optocoupler. It has 400 pulses/revolution for each phase and 1600 pulses/ revolution for two phases, 4-times output. This rotary encoder supports a maximum speed of 5000 rpm. The photoelectric rotary encoder has an NPN open collector output. It can be used directly with a microcontroller with internal pull-up resistors. If none are available internally, the encoder comes with two separate 10KΩ pull-up resistors. The encoder has a 750L05 voltage regulator chip with an input range of 4.8V-24V, making it compatible with Arduino, STM32, SPS, and other types of microcontrollers.
