As a convenience to you, it has been included in package Cylinder, Threaded - M30. When the operating temperature is -25°C~70°C, proximity sensors can function well. If you want proximity sensors to perform at their best, you should set their supply voltage to 24V. It is imperative that the rate is set to 800Hz in order to ensure that the proximity sensors are functioning correctly. The current that the reed switch's internal contacts pass should be 500μA to make the proximity sensors work well.
