With the Cylinder, Threaded - M30 package, it is included for your convenience. When the operating temperature is -25°C~70°C, proximity sensors can function well. -25°C is the lowest operating temperature for proximity sensors. Proximity sensors cannot operate above 70°C. DC circuits can handle a maximum voltage of 24V without damaging proximity sensors. DC circuits with proximity sensors should not have currents lower than 12V, otherwise, they are dangerous.
