E3RA-DN21 Overview
The temperature of photoelectric sensor should be set to -25°C~55°C to ensure reliable performance. The voltage of this electronic components should be given 10V~30V into a circuit or system to make it work. Sensors with a response time of 500μs are considered ideal. As a precaution, the photoelectric sensor must operate at -25°C degrees Celsius at all times. The maximum operating temperature is 55°C, so it's reliable. Photoelectric sensor output current should be 100mA for it to operate. A photoelectric sensor can withstand a voltage of 30V in a DC circuit without being damaged. There is no limit to the voltage at which this photoelectric sensor can work, including zero. This package contains photoelectric sensors for your convenience.
