Precision Linear Sensors

Precision linear sensors offer performance improvements over basic linear sensors.  They do this with an additional "fine" set of sensor coils.  This fine track delivers high precision and accuracy, while a coarse track delivers an absolute output.  

The CTU chip connected to the sensor combines the outputs of both tracks so that the position it reports to the host is always absolute, precise and accurate.

Precision linear sensors can be Type 2 or Type 6 sensors (find out more about how sensors are classified and what this means for CTU selection in our FAQ). Type 2 sensors offer greater measuring range than Type 6.A single CAM204 CTU chip can operate up to two Type 6 sensors, including a mix of linear and rotary.  The CAM204 can operate a single Type 2 sensor.
