Linear Sensors


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.


Basic linear sensors are robust, precise and simple.  This set of sensors is also narrow - 10mm wide - which means they can fit in tight spaces.  Standard sensors are available from 25mm to 300mm measuring length.

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 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.  

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.  


Founded in 2007, CambridgeIC has developed single chip processors and a set of standard sensor designs and integration tools. These help customers embed resonant inductive sensing inside their products, by drawing on modular and well proven components.
