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 4 pins is included in this electronic component. If you want to get the most out of proximity sensors, you should set the supply voltage to 30V. For the proximity sensors to work properly, the rate needs to be 10Hz. It's important that the reed switch's internal contacts pass 200mA for the proximity sensors to work.
