With the Cylinder, Threaded - M18 package, it is included for your convenience. When the operating temperature is -25°C~70°C, proximity sensors can function well. There are 4 pins on this electronic component. To ensure that proximity sensors function properly, the rate should be 25Hz. For the proximity sensors to work properly, the reed switch's internal contacts should pass 300mA current. With a nominal supply current of 13mA, the proximity sensors will operate normally.
