I've included it in the Module package for your convenience. With an operating temperature of -25°C~70°C, proximity sensors can work efficiently. A component with 3 pins is included in this electronic component. For the proximity sensors to work properly, the rate needs to be 1kHz. It's important that the reed switch's internal contacts pass 100mA for the proximity sensors to work. You should set the current of this electronic part to 15mA in order to maximize efficiency.
