1-Channel EL817 Optocoupler 12V
With this optocoupler, you can connect inductive and capacitive NPN or PNP sensors to an Arduino. The optocoupler module is designed for 12V. If you want to operate it at higher voltages, you can replace the R1 resistor with a suitable one. This 1-channel optocoupler is perfect for retrofitting a capacitive ABL EZABL sensor/autolevel sensor to a 3D printer. We successfully use the optocoupler on our Creality CR-10 and Ender-3 3D printers.
You can find a very good guide on how to retrofit an autolevel sensor to a 3D printer on Thingiverse at the following link:
