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.
DownloadOutline
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.
Principle and major types
A light beam is emitted from the light emitting element (laser) in the transmitter and is received with the light receiving element in the receiver.
