E3RA-TN21 Overview
It is recommended to set the temperature of a photoelectric sensor to -25°C~55°C in order to ensure reliable operation. In order for these electronic components to function, they must be connected to a circuit or system with a voltage of zero. The ideal response time for a photoelectric sensor is 500μs. The photoelectric sensor operates at a minimum working temperature of -25°C to ensure reliability. It is possible to operate on a reliable level at a temperature of 55°C. Photoelectric sensors work properly when the 4 pins are connected. The output current of a photoelectric sensor must be 100mA. There is a maximum voltage of 30V that can be applied to a photoelectric sensor in a DC circuit without damaging it. A photoelectric sensor such as this can operate at a voltage as low as possible, such as 0 volts. A photoelectric sensor is included in the Radial package for convenience.
