This application uses a high-performance Fiber Amplifier with differentiation and other functions.
This Amplifier with differentiation and an area-detection fiber head detects falling workpieces.
Know-How
Conventional sensors did not provide stable detection when the light intensity changes according to quantity of workpieces.
Benefit / Efficiency
Differential operation makes it possible to detect only falling workpieces by ignoring changes in light intensity over time caused by falling workpieces.
