E3FB-RN21 Overview
A reliable performance can be assured by setting the temperature of the photoelectric sensor to -25°C~55°C. For these electronic components to function, a circuit or system should have 0 volts. A response time of 500μs is considered ideal for photoelectric sensors. A photoelectric sensor can be damaged by the maximum DC voltage of 30V. A photoelectric sensor such as this can operate at a voltage as low as possible, such as 0 volts. The supply voltage of photoelectric sensor should be set to 30V for best efficiency.
