To make it easier for you, this Sensor is included with the Cylinder, Threaded - M18 package. The proximity sensors can work well with the operating temperature of 0°C~60°C. It is recommended that the supply voltage of proximity sensors be set to 24V for maximum efficiency. The lowest operating temperature of the proximity sensors can be reached 0°C. The operating temperature of the proximity sensors cannot be higher than 60°C. The maximum voltage of 24V can be applied to the proximity sensors without damage in DC circuit. The current of the proximity sensors in the DC circuit should not be lower than 12V, otherwise, it will be dangerous. The frequency of proximity sensor should be 10kHz to make it work.
