A while back we featured a magnetic rotary encoder that [LongHairedHacker] designed. The heart of the system is an AS5043 magnetic rotary sensor which runs from $6.5-$11 and has a 10 bits precision.
Encoders are critical to the production of advanced electronics, one of the fastest growing and advancing industries in the world. Rotary, angle and linear encoders are all used in one form or another ...
Rotary and linear optical encoders are common in position and motion sensing. Here, a disc or plate containing opaque and transparent segments passes between an LED and detector to interrupt a light ...
