This is included with the Cylinder, Threaded - M30 package for your convenience. A temperature of -25°C~70°C is a suitable operating temperature for proximity sensors. To maximize the efficiency of proximity sensors, the supply voltage should be set to 60V. Ensure that the proximity sensor switch performs its function by setting the rate to 150Hz. In order for proximity sensors to work properly, the reed switch's internal contacts should pass 100mA current.
