It's important to set the photoelectric sensor's temperature to -25°C~70°C for reliable performance. To make these electronic components work, they should be supplied with 10V~30V voltage. Photoelectric sensors are considered to have an optimal response time of 1ms. 4 pins must be connected to the photoelectric sensor to make it work. Whenever a photoelectric sensor is operating, the output current should be zero. When applied to a DC circuit, the maximum voltage that can be applied to the photoelectric sensor without damaging it is 30V. There are some photoelectric sensors that can work with low voltages, such as 10V. A maximum output current of 100mA allows for photoelectric sensors to work.
