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 -25°C~70°C. It is recommended that the supply voltage of proximity sensors be set to 30V for maximum efficiency. The current that the reed switch's internal contacts pass should be 200mA to make the proximity sensors work well. The maximum voltage of 30V 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 10V, otherwise, it will be dangerous.
