It is included with the package Module to simplify your life. With an operating temperature of -25°C~70°C, proximity sensors can work efficiently. The pins on this electronic component are 2. It is recommended that the supply voltage of proximity sensors be set to 24V for maximum efficiency. If the rate is 500Hz, then the proximity sensors will function. It is essential that the reed switch's internal contacts pass 50mA current to ensure that the proximity sensor functions as designed. Set the current of this electronic part to 100mA for maximum efficiency.
