In order to make things easier for you, it's included in the Cylinder, Threaded - M8 package. It is possible to operate proximity sensors successfully at a temperature of -25°C~70°C. Maximum efficiency is achieved by setting proximity sensors' supply voltage to 24V. The proximity sensors can be operated at temperatures as low as -25°C. A proximity sensor's operating temperature cannot exceed 70°C. It is important for the rate to be 1kHz so that the proximity sensors will work. To work well, the reed switch's internal contacts should pass 500μA current.
