It is included with the package Cylinder, Threaded - M5 to simplify your life. It is possible for proximity sensors to function well at -25°C~70°C. A 3 pin electronic component is used here. Proximity sensors should have their supply voltage set to 30V for maximum effectiveness. To ensure that proximity sensors work properly, the rate should be set to 4kHz. To make the proximity sensors work properly, the internal contacts of the reed switch must pass 100mA.
