The Cylinder, Threaded - M12 package already includes it for your convenience. When the operating temperature is -25°C~70°C, proximity sensors will work well. -25°C is the lowest operating temperature of the proximity sensors. There can be no higher temperature for the proximity sensors than 70°C. In DC circuits, proximity sensors can receive a voltage up to 24V without being damaged. DC proximity sensors should not have currents lower than 12V, or they could damage the circuit.
