It's included in Cylinder, Threaded - M12 so you can find it easily. When the operating temperature is -10°C~55°C, proximity sensors can function well. Pins 3 on this electronic component. In order to achieve maximum efficiency, proximity sensors should be supplied with a voltage of 24V. It is imperative that the rate is set to 10Hz in order to ensure that the proximity sensors are functioning correctly. 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 2.2mA to maximize efficiency.
