How to apply ES38 NPN output rotary encoder to MCU

The ES38 series rotary encoder produced by CALT sensor has a variety of outputs to choose from: NPN (8-24V power supply), PNP (8-24V power supply), Voltage (5V power supply) . Usually we recommend that customers purchase voltage output encoders directly if they are used in single-chip microcomputers, but what if you accidentally purchase the wrong …
