Optical limit switch light barrier with cable

This limit switch is suitable for 3D printers as an end switch or reference switch. The plug pinout is designed so that you can directly plug the limit switch into a Ramps 1.4 board. You can also use the switch for other Arduino projects and, for example, build a rotary encoder. There is also a red LED mounted on the module that goes out when the switch is actuated. The output signal varies in voltage depending on the cover of the light barrier. So it can be read with the Arduino either analog or digital.
