Detection based on “Light”
What is a “received light” recognition type laser sensor?

Sensors come in a wide variety, and each type has strengths and weaknesses. This section provides a detailed look at laser sensors that detect based on received light intensity.

Outline

A laser sensor uses a “laser” to emit light in a straight line. Its visible beam spot makes alignment and positioning very easy. Since the light beam is focused, the sensor can be installed without worries about stray light.
