In addition to encoders and machine vision systems/solutions, FSI Technologies Inc. designs and manufactures custom photoelectric sensors too. Many OEMs use sensors as an inexpensive and effective way of assisting in automatic inspection. Sensors are most often used to measure speed (or RPM), presence or absence of a part and as a way to calculate distance/positioning. If you think your application would benefit from a leading edge, specialized sensor product, one of our engineers can steer you in the right direction.
