Position measurement using arc sensors


Arc Position Sensors from CambridgeIC


For engineers who need precise, robust measurement of angle CambridgeIC’s arc position sensors provide absolute position measurement for challenging applications in complex product designs.

Robust, precise, inductive position sensing

Based on innovative resonant inductive position sensing technology, CambridgeIC’s position sensors use designs integrated into conventional PCBs to measure angle with a sensor arranged along an arc. This gives an accurate angle position sensor which has low integration costs, is stable over time and extremely robust. Designers can provide absolute rotary and arc position measurement with high reliability in the most challenging applications.

Position sensing for tight corners

How challenging? When compared to optical or Hall Effect encoders, this solution is very tolerant of dirt, dust, moisture, vibration and shock, misalignments and wide measuring gaps. It is particularly cost effective where there is limited room or the system needs to sense position on many axes.

This makes CambridgeIC arc position sensors suitable for many applications, including surveillance camera control, satellite steering, intelligent valves and automotive suspension systems.

Designs are available for a huge range of geometries - arc position measurement, rotary position measurement and linear position sensing and support is available to design custom sensors.

Working with CambridgeIC position sensors is straightforward - sensor blueprints are available in Gerber format to integrate with customers PCB. These designs work with CambridgeIC’s central tracking unit chips (CTUs) to provide continuous calculation of target position. For evaluation or low volume production assembled sensor units are also available.
