We have included it with the Cylinder, Threaded - M18 package in order to make your life easier. The proximity sensors can work well with the operating temperature of -25°C~70°C. There are 4 pins on this electronic component. If you wish to obtain maximum eficiency, it is recommended to set the supply voltage of proximity sensors to 30V. It is important for the rate to be 400Hz so that the proximity sensors will work. Reed switches work well with proximity sensors when their internal contacts pass 200mA current. If you want to maximize efficiency, you should set the current of this electronic part to 200mA. The proximity sensor must have a frequency of 400Hz.
