E3FA-LN21 Overview

For reliable performance, set the temperature of the photoelectric sensor to -25°C~55°C. The voltage of this electronic components should be given 10V~30V into a circuit or system to make it work. The ideal response time for photoelectric sensors is 500μs. 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. 4 pins must be connected for the photoelectric sensor to work. For a photoelectric sensor to function, the output current should be 100mA. It is possible to apply a voltage of 30V to the photoelectric sensor in a DC circuit without damaging it. Photoelectric sensors can operate at low voltages, such as 10V. Photoelectric sensors are included as a convenience in the package 100.
