We have included it as part of the Cylinder, Threaded - M18 package for your convenience. When the operating temperature is -25°C~70°C, proximity sensors can function well. Electronic components have 4 pins. To maximize the efficiency of proximity sensors, the supply voltage should be set to 30V. Proximity sensors can operate at temperatures as low as -25°C. There is a maximum operating temperature of 70°C for proximity sensors. It is important that the rate of the proximity sensor switch be set to 500Hz to ensure that it is properly functioning. It is essential that the reed switch's internal contacts pass 200mA current to ensure that the proximity sensor functions as designed. It is recommended that you set the current of this electronic part to 200mA if you wish to maximize efficiency. A proximity sensor should have a frequency of 500Hz in order to function properly.
