It is recommended to set the temperature of a photoelectric sensor to -20°C~50°C in order to ensure reliable operation. Electronic components require a voltage of 10V~30V to function in a circuit or system. It's ideal for photoelectric sensors to have a response time of 6.5ms, 3.5ms. You've got to connect the 2 pins to the photoelectric sensor for it to work.
