This is included in the Cylinder, Threaded - M18 package to make it easier for you to use. It is possible to use the proximity sensors at -25°C~70°C. To maximize the efficiency of proximity sensors, the supply voltage should be set to 24V. It is recommended that the rate be set to 2kHz in order to ensure that the proximity sensor switches operate properly. ldeally, the reed switch's internal contacts should pass 10mA to make the proximity sensors work properly.
