The Cylinder, Threaded - M12 package already includes it for your convenience. When the operating temperature is -40°C~70°C, proximity sensors will work well. Electronic components with pins 4 are available. If you want proximity sensors to perform at their best, you should set their supply voltage to 24V. -40°C is the lowest operating temperature of the proximity sensors. There can be no higher temperature for the proximity sensors than 70°C.
