E3S-AT86

Overview of Omron E3S-AT86

The Omron E3S-AT86 is a medium-size through-beam photoelectric sensor designed for long-distance detection up to 7 meters. It features a red LED light source with a wavelength of 660 nm and operates on a 10 to 30 V DC power supply. The sensor comes with an M12 connector for easy installation and provides selectable Light-ON or Dark-ON operation modes. It offers a fast response time of 0.5 ms and includes protection circuits such as reverse polarity protection and output short-circuit protection for enhanced reliability.
