E3RB-RN21 Overview

In order to work reliably, the photoelectric sensor should be set to -25°C~55°C. If you want these electronic components to work, you need to apply 10V~30V. It is generally considered that photoelectric sensors have a response time of 500μs. It is imperative that the photoelectric sensor is operated at a minimum temperature of -25°C in order to ensure its reliability. In order to ensure reliable operation, the maximum operating temperature should not exceed 55°C. DC circuit can apply a maximum voltage of 30V without harming the photoelectric sensor. As low a voltage as possible, such as 0 volts, can be used for this photoelectric sensor. For optimal efficiency, set the supply voltage to 30V. A photoelectric sensor is included in the Metal package for convenience.
