Omron E3S-AR61 Through-Beam Photoelectric Sensor

The Omron E3S-AR61 Through-Beam Photoelectric Sensor is a non-contact object detector from Omron’s E3S line, designed to sense interruptions in a beam across a gap in automated systems. In a through-beam setup, an emitter and receiver are positioned opposite each other so that any object breaking the beam triggers a change in output, enabling reliable detection without mechanical contact. The model includes an 11-inch cord, offering flexible wiring and easier integration into compact control panels or machine frames. With the exact part number Omron E3S-AR61, this sensor provides a compact, straightforward sensing solution for applications requiring reliable beam interruption detection in manufacturing and packaging environments, and is well-suited to setups with a clear line of sight where fast response is beneficial.
