Product Specifications

Technical details and manufacturing context for Light Source/Detector

Definition
A combined optical component within feedback devices (encoders/resolvers) that generates light signals and detects their reflection/interruption to measure rotational position, speed, or linear displacement with high precision.
Working Principle
The light source (typically LED or laser diode) emits a beam that interacts with a coded disk or strip. The detector (photodiode or phototransistor array) receives the modulated light pattern, converting optical signals into electrical signals for position/speed calculation.
Common Materials
Gallium Arsenide (GaAs) for LEDs, Silicon for photodiodes, Optical-grade plastics/glass
