You will find it included in the Cylinder, Threaded - M18 package to make it easier for you. Temperatures of -25°C~70°C are ideal for proximity sensors. For maximum efficiency, the proximity sensors should be supplied with a voltage of 24V. To ensure that proximity sensors function properly, the rate should be 2kHz. To make the proximity sensors work properly, the internal contacts of the reed switch must pass 10mA.
