I've included it in the Cylinder, Threaded - M18 package for your convenience. It is possible to operate proximity sensors successfully at a temperature of -40°C~70°C. It is recommended that the supply voltage of proximity sensors be set to 30V to achieve maximum efficiency. It is recommended that the rate be set to 15Hz in order to ensure that the proximity sensor switches operate properly. For the proximity sensors to work properly, the reed switch's internal contacts should pass 200mA current.
