E3RB-TN21 Overview

A reliable performance can be assured by setting the temperature of the photoelectric sensor to -25°C~55°C. It's important that 10V~30V is applied to the circuit or system for these components to work. It is generally considered that photoelectric sensors have a response time of 500μs. In order to ensure reliability, the photoelectric sensor must operate at a minimum working temperature of -25°C. The maximum operating temperature is 55°C, so it's reliable. DC circuit can apply a maximum voltage of 30V without harming the photoelectric sensor. This photoelectric sensor can work at as low a voltage as possible, such as 10V. Optimal performance can be achieved by setting the supply voltage of the photoelectric sensor to zero. As a convenience, here are some photoelectric sensors included in the Radial package.
