CambridgeIC's linear sensor designs measure the precise linear position of a target. Sensors are built using conventional PCB technology, so they are accurate, stable and cost effective.
Sensors work with CambridgeIC’s Central Tracking Unit (CTU) family of single chip processors to provide high-quality position data to a host device.
Standard sensor designs are available as Sensor Blueprints in Gerber format. This enables a customer's PCB designer to integrate the sensor design with their own PCB. In turn this allows them to select a mounting and connection scheme. It also allows a customer's electronics to share the same PCB as the sensor.
CambridgeIC sells sample quantities of assembled sensors for evaluation and customer prototyping.
Type B Linear Sensors
Type B sensors work only with the CAM622. Both sensors and targets are built from PCBs for low cost, robustness and small size. Standard designs are available from 40mm to 200mm measuring length.
Basic Linear Sensors
Basic linear sensors are robust and simple. Standard designs are available from 25mm to 300mm measuring length.
Short Stroke Linear
Short Stroke Linear sensors are built using conventional PCB technology and detect the position of a standard target without mechanical or electrical contact. They are robust, simple and tolerant of misalignment and large gaps.
Axial Sensors
Axial linear sensors measure the position of a target which is allowed to rotate about the axis of measurement. This configuration suits applications where the moving part's rotation can not be constrained, such as float level sensors, variable area flow meters and syringe plunger position measurement.
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.
