Including it in package Cylinder, Threaded - M12 will make it easier for you. A temperature of -25°C~70°C is a suitable operating temperature for proximity sensors. -25°C is the lowest operating temperature that proximity sensors can reach. Neither the proximity sensors nor their operating temperatures may exceed 70°C. In DC circuits, proximity sensors can be operated at maximum voltages 24V. It is unsafe for proximity sensors in the DC circuit to operate below 12V.
