In order for the photoelectric sensor to work reliably, it should be set to -25°C~55°C degrees Celsius. For these electronic components to function, a circuit or system should have 0 volts. A response time of 1ms is considered ideal for photoelectric sensors. The photoelectric sensor operates at a minimum working temperature of -25°C to ensure reliability. It is possible to operate on a reliable level at a temperature of 55°C. In order to make the photoelectric sensor work properly, it must have 4 pins connected.
