A reliable performance can be assured by setting the temperature of the photoelectric sensor to -20°C~60°C. To make these electronic components work, they should be supplied with 10V~30V voltage. It's ideal for photoelectric sensors to have a response time of 500μs. The photoelectric sensor must be connected to the 4 pins in order to function properly. Whenever a photoelectric sensor is operating, the output current should be zero. The photoelectric sensor is not damaged by voltage of 30V applied in DC circuit. In this photoelectric sensor, the voltage can be as low as possible, such as 0 volts.
