In order to make things easier for you, it's included in the Cylinder, Threaded - M30 package. When the operating temperature is -25°C~70°C, proximity sensors can function well. It's got 4 pins. To maximize efficiency, proximity sensors should have their supply voltage set to 30V. To ensure that the proximity sensors perform their duties, the rate should be 250Hz. In order for proximity sensors to work properly, the internal contacts of the reed switch should pass 200mA. Set the current of this electronic part to 200mA for maximum efficiency. In order for the proximity sensor to work, its frequency should be 250Hz.
