E3RA-RN21 Overview
For reliable performance, set the temperature of the photoelectric sensor to -25°C~55°C. It's important that 10V~30V is applied to the circuit or system for these components to work. Sensors with a response time of 500μs are ideal. It is essential that the photoelectric sensor operates at a minimum working temperature of -25°C to guarantee its reliability. Reliable operation is possible at 55°C. You've got to connect the 4 pins to the photoelectric sensor for it to work. At the output, the photoelectric sensor should have a current of 100mA. It is possible to apply a voltage of 30V to the photoelectric sensor in a DC circuit without damaging it. Ideally, this photoelectric sensor should operate at a low voltage, such as 0V. Several photoelectric sensors are included with the Radial package for your convenience.
