Standard 18mm round photoelectric sensors detect presence in several ways: diffuse (light reflects from the target object back to the sensor), retroreflective (object interrupts light rebounding off a fixed reflector), or through-beam (object obstructs light traveling from an emitter to a receiver). Available models offer detection ranges up to 50m, and are offered in plastic or metal bodies.
Standard 18mm round photoelectric sensors are one of the most common industrial photoelectric sensors, with a variety of styles and operational technologies to suit most applications. Available models offer detection ranges up to 50m, many in plastic or metal bodies.
