To make it easier for you, this Sensor is included with the Cylinder, Threaded - M30 package. The proximity sensors can work well with the operating temperature of -25°C~70°C. This electronic component has 4 pins. It is recommended that the supply voltage of proximity sensors be set to 30V for maximum efficiency. The rate should be 100Hz to ensure that switch of the proximity sensors performs its function. The current that the reed switch's internal contacts pass should be 200mA to make the proximity sensors work well. If you want to maximize efficiency, you should set the current of this electronic part to 200mA. The frequency of proximity sensor should be 100Hz to make it work.
