E3FA-RP21 Overview

For reliable performance, set the photoelectric sensor to -25°C~55°C. It is necessary to provide these electronic components with a voltage of 0 to make them work in a circuit or system. A photoelectric sensor with a response time of 500μs is considered to be ideal. The photoelectric sensor operates at a minimum working temperature of -25°C to ensure reliability. Reliable operation is possible at 55°C. You've got to connect the 4 pins to the photoelectric sensor for it to work. Photoelectric sensors need an output current of 100mA in order to operate. It is possible to apply a voltage of 30V to the photoelectric sensor in a DC circuit without causing damage. It is possible to operate this photoelectric sensor at a voltage as low as possible, for example at zero volts. Photoelectric sensors should have a supply voltage of 24V in order to be most effective.
