When to use a Vision Sensor for Error-Proofing Applications

Vision sensors are powerful Poka-Yoke tools ideal for error proofing your process. However, traditional sensors still solve more applications at a much lower cost. So, how do you decide when to jump up to a vision sensor? There are three application categories that require the use of a vision sensor, which include:


  1. Parts are not well fixtured: If the part is not contained in a fixture, or there is no opportunity to bring the part into an inspection station that has better tolerance, then a vision system is the best choice.
    Example: parts directly on moving conveyor belt.

  2. Multiple inspection points per part: If there are multiple details on the part to error-proof, vision sensors are recommended.
    Example: inspecting multiple pins in a connector.

  3. Location of detail is not known or is random: If the location of the detail on the part in question is not constant or its location is random, then vision sensors  are an ideal choice.
    Example: random location of bolt on stud.
