O6D laser distance sensor: Time-of-flight technology

Common CMOS-based distance sensors use the triangulation operating principle. When mounting restrictions require these sensors to be mounted at an angle, insufficient light from the target is reflected back to the sensor to determine the distance.

The O6D time-of-flight principle does not rely on triangulation. When light bounces off the target, the phase pattern of the transmitted light shifts and the shift is directly proportional to the distance. The sensor only requires a small amount of reflected light to accurately determine the distance.

Advantages of time-of-flight measurement:

• Robust detection of small reflective, shiny or black objects 
• Multicolored objects are reliably detected
• Due to background suppression and laser light, the O6D sensors work reliably when there are interferences in the environment – ​​such as movements, reflections and extraneous light
• Fast installation thanks to color and angle independence
• Measured distance information via IO-LInk
