E3FA-VP21 Overview

It is recommended that the photoelectric sensor is set at -25°C~55°C to ensure reliable performance. In order for these electronic components to work, their voltage must be set to 10V~30V. A photoelectric sensor is considered ideal if its response time is 500μs. The photoelectric sensor operates at a minimum working temperature of -25°C to ensure reliability. It is possible to operate on a reliable level at a temperature of 55°C. 4 pins must be connected to the photoelectric sensor for it to function correctly. Whenever a photoelectric sensor is operating, the output current should be zero. Photoelectric sensors can be damaged by a voltage of 30V in DC circuit. Unlike most photoelectric sensors, this one operates at a very low voltage such as 0 volts.
