Detection based on “light”
Features of “position” recognition type laser sensors


Not just for presence detection - measurement is also possible

Certain models can measure distance and position with higher accuracy than a simple sensor. The following are some examples of KEYENCE products:

CCD thrubeam model

CCD thrubeam model(IG Series)

A laser is emitted from a transmitter and then is received by a CCD light receiving element. The area where the laser is interrupted is identified clearly on the CCD. This model can be used for in-line position detection or outer diameter measurement of a target.

High accuracy CMOS reflective model

High accuracy CMOS reflective model(IL/IA Series)

Reflected light is received with a CMOS light receiving element and the position is determined based on the triangulation principle. This model can output the position information with an analogue signal.
