It is included with the package Cylinder, Threaded - M18 to simplify your life. A temperature of -25°C~70°C is a suitable operating temperature for proximity sensors. The maximum efficiency of proximity sensors can be achieved by setting their supply voltage to 253V. It is recommended that the rate be set to 25Hz in order to ensure that the proximity sensor switches operate properly. Reed switches are designed to use reed switches with internal contacts that pass 200mA current. It is possible to apply a voltage of 30V to proximity sensors without causing damage to them in DC circuits. A DC circuit with proximity sensors should not have a current lower than 10V, otherwise it could be dangerous.
