We have included it with the Cylinder, Threaded - M8 package in order to make it easier for you. At temperatures of -25°C~70°C, proximity sensors work well. It has 3 pins. If you wish to obtain maximum eficiency, it is recommended to set the supply voltage of proximity sensors to 30V. If you wish to ensure that the proximity sensors are operating properly, the rate should be 1.5kHz. Reed switches work well with proximity sensors when their internal contacts pass 200mA current. In a DC circuit, the maximum voltage of 30V is pemissible for proximity sensors. In a DC circuit, the proximity sensors must have a current higher than 10V. The best way to increase the efficiency of this electronic part is to set the current to 200mA. In order for the proximity sensor to work, the frequency should be 1.5kHz.
