Abstract
A non-contact linear absolute position sensor includes a first magnetic encoder having n+1 pole pairs, a second magnetic encoder having n pole pairs and located and aligned with the first magnetic encoder so as to cover a linear distance. The magnetic encoders are affixed to a traveling body. Two pairs of Hall Effect sensors are located near each of the first and second magnetic encoders and are configured to generate linear position signals. A processor is provided to process the linear position signals to generate an output signal indicative of a linear absolute position of the traveling body.
