It is recommended that the photoelectric sensor is set at -25°C~55°C to ensure reliable performance. If you want these electronic components to work, you need to apply 12V~24V. Sensors with a response time of 1ms are ideal. Ensure reliability by operating the photoelectric sensor at -25°C degrees Celsius or lower. Reliable operation is enabled by a maximum operating temperature of 55°C. The 4 pins on the photoelectric sensor need to be connected for it to work.
