This is included with the Cylinder, Threaded - M30 package for your convenience. A temperature of -25°C~70°C is suitable for the operation of proximity sensors. In order to maximize the efficiency of proximity sensors, it is recommended that the supply voltage be set to 30V. It is important that the rate of the proximity sensor switch be set to 150Hz to ensure that it is properly functioning. To make the proximity sensors work properly, the internal contacts of the reed switch must pass 200mA.
