In order to make things easier for you, it's included in the Cylinder, Threaded - M30 package. It is possible to operate proximity sensors successfully at a temperature of -40°C~70°C. Maximum efficiency is achieved by setting proximity sensors' supply voltage to 30V. It is important for the rate to be 200Hz so that the proximity sensors will work. To work well, the reed switch's internal contacts should pass 200mA current.
