It is recommended that the photoelectric sensor is set at -25°C~55°C to ensure reliable performance. Electronic components should be connected to a circuit or system by 12V~24V voltage. Sensors with a response time of 1ms are considered ideal. As a precaution, the photoelectric sensor must operate at -25°C degrees Celsius at all times. For reliable operation, a maximum operating temperature of 55°C is required. It is necessary to connect 4 pins to make the photoelectric sensor work.
