Absolute Position Sensor

Absolute encoders read out a multi bit digital word corresponding to absolute position.

Absolute position sensor.

The rotation of this horizontal component is sensed over a wide range up to 360º and processed by. A position sensor is a sensor that facilitates measurement of mechanical position. Optical encoders provide the highest resolution and accuracy but they are vulnerable to contamination. Encoders are available with both optical encoder and magnetic encoder sensing engines.

This unique sensing principle applied to a position sensor ic results into an impressive robustness of the position signal over the mechanical airgap off axis tolerances. Absolute position sensors are very different from incremental sensors. The rotation of this horizontal component is sensed over a wide range up to 360º and processed by the on chip dsp to ultimately report the absolute angular position of the. A key step in selecting a suitable position sensor is understanding the requirements of sensor size resolution repeatability accuracy mounting constraints and environmental ruggedness.

It needs a reference point in order to start measuring. When you say incremental position sensor it implies a change in position. Triaxis absolute position sensor ic mlx90340. A position sensor may indicate absolute position location or relative position displacement in terms of linear travel rotational angle or three dimensional space.
