As an added convenience, the Cylinder, Threaded - M30 package includes it. Temperatures of -25°C~70°C are ideal for proximity sensors. It is possible to operate proximity sensors at -25°C. A proximity sensor cannot operate at a temperature higher than 70°C. DC circuits can be operated with a voltage of 24V without damaging the proximity sensors. In a DC circuit, proximity sensors should not be operating at a current below 12V, otherwise they will be dangerous.
