It is included with the Cylinder, Threaded - M18 package as a convenience to you. It is possible to operate proximity sensors successfully at a temperature of -25°C~70°C. It's got 4 pins. To achieve maximum efficiency, proximity sensors should be powered by 30V. In order to ensure that the proximity sensors perform their function, the rate should be set to 400Hz. The proximity sensors work best if the reed switch's internal contacts pass 200mA. For maximum efficiency, you should set the current of this electronic component to 200mA. You need to set the frequency of the proximity sensor to 400Hz if you want it to work.
