To maintain reliable performance, the photoelectric sensor should have a temperature of -25°C~55°C. If these electronic components are to work, they should receive 12V~24V voltage into the circuit or system. For photoelectric sensors, 1ms is considered an ideal response time. This photoelectric sensor can only function properly if the 3 pins are connected. If you want to get the best performance from a photoelectric sensor, you should set the supply voltage to 24V.
