It is included with the package Cylinder, Threaded - M18 to simplify your life. When the operating temperature is -25°C~70°C, proximity sensors can function well. Pins 4 on this electronic component. A proximity sensor's supply voltage should be set to 30V for maximum efficiency. To ensure that proximity sensors work properly, the rate should be set to 500Hz. In order for proximity sensors to work properly, the internal contacts of the reed switch should pass 200mA. Set the current of this electronic part to 200mA if you want maximum efficiency. The proximity sensor must have a frequency of 500Hz.
