It is included with the package Cylinder, Threaded - M30 to simplify your life. It is possible for proximity sensors to function well at -25°C~70°C. A 4 pin electronic component is used here. Proximity sensors should have their supply voltage set to 24V for maximum effectiveness. A proximity sensor's lowest operating temperature is -25°C. Temperatures above 70°C are not allowed for proximity sensors. To ensure that proximity sensors work properly, the rate should be set to 1.3kHz. To make the proximity sensors work properly, the internal contacts of the reed switch must pass 500μA.
