Photoelectric sensors should be set at 0°C~70°C for reliable performance. It is necessary to provide these electronic components with a voltage of 0 to make them work in a circuit or system. Sensors need to work at 0°C to be reliable. A maximum operating temperature of 70°C allows for reliable operation. In order for the photoelectric sensor to function, the 3 pins must be connected. Photoelectric sensors require an output current of 50mA to operate. The photoelectric sensor can withstand a maximum voltage of 7V in a DC circuit without sustaining damage. Photoelectric sensors have the capability of operating at very low voltages, such as 4V.
