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 500Hz. In DC circuits, proximity sensors can withstand a maximum voltage of 30V. There must be at least 10V current flowing through the proximity sensors in the DC circuit to prevent an electric shock. You should set the current of this electronic part to 10mA in order to maximize efficiency.
