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. The supply voltage of proximity sensors should be set to 30V for maximum efficiency. To ensure that proximity sensors function properly, the rate should be 500Hz. For the proximity sensors to work properly, the reed switch's internal contacts should pass 200mA current. The current of this electronic part should be set to 200mA to maximize efficiency. For proximity sensors to work, the frequency should be 500Hz.
