Encoders or motion sensors are electromechanical feedback devices that detect rotary or linear movements and translate them into interpretable electrical signals for the controller.
The device consists of a light source, lens, patterned code wheel and an array of photodetectors. The code wheel rotates between the light source and photodetectors causing the light beam to be interrupted by the pattern of spaces and bars on the code wheel. The photodetectors generate currents according to the patterns, which are signal conditioned within the device and presented to the outside world in appropriate electrical signal form.
This paper explores how Avago's AEAS-7000 Absolute Encoder and benefits one will experience with this product.
