E3RB-DN21 Overview
To make sure the photoelectric sensor works, set its temperature to zero. In order for these electronic components to work, they should be given 10V~30V voltage. A photoelectric sensor with a response time of 500μs is considered to be ideal. As a precaution, the photoelectric sensor must operate at -25°C degrees Celsius at all times. For reliable operation, a maximum operating temperature of 55°C is required. Photoelectric sensors are designed to operate with a current of 100mA at the output. The supply voltage of photoelectric sensor should be set to 30V for best efficiency. A photoelectric sensor is included in the 100 package for convenience.
