To make sure your photoelectric sensor is reliable, set its temperature to -40°C~70°C. For these electronic components to function, they require a voltage of 20VAC~250VAC to be applied to a circuit or system. The ideal response time for photoelectric sensors is 16ms. It is necessary to connect 3 pins to make the photoelectric sensor work. In order for a photoelectric sensor to function, the output current should be 300mA.
