E3FA-VN21 Overview

To make sure the photoelectric sensor works, set its temperature to zero. For these electronic components to function, a voltage of 10V~30V should be applied to a circuit or system. Photoelectric sensors are considered to have an optimal response time of 500μs. For photoelectric sensors to work, they have to be at -25°C. 55°C is the maximum operating temperature that is safe and reliable. You've got to connect the 4 pins to the photoelectric sensor for it to work. In order for a photoelectric sensor to function, the output current should be 100mA. DC circuit can apply a maximum voltage of 30V without harming the photoelectric sensor. In this photoelectric sensor, the voltage can be as low as possible, such as 0 volts.
