The very small, efficient light barriers and sensors in the O-20 series can be easily integrated. The devices, which are available as sensors, reflective or through-beam sensors, detect the smallest parts in the entire active zone.
Diffuse reflective sensors
Energetic retroreflective diffuse sensors are economic sensors with a transmitter and receiver in one housing. The working distance and the brightness of the object and background influence object detection, wherein bright objects can be recognized well against dark backgrounds.
Retroreflective sensors make long ranges possible, with simple assembly and a high degree of system availability. The emitted light is reflected back by a reflector and evaluated in the retroreflective sensor.
Through-beam sensors consist of transmitter and receiver, each of which are arranged in a housing. Transmitter and receiver are mounted opposite one another. Nontransparent, shiny and reflective objects can be reliably recognized. Through-beam sensors make long ranges possible, with the highest degree of functional safety. Cleaning and maintenance cycles can be reduced to a minimum through the use of through-beam sensors.
