For engineers who need contactless position sensors that are precise and robust CambridgeIC’s inductive non contact solutions produce position sensors for many situations. They are a good contactless sensor alternative to Hall effect or optical encoder solutions, producing absolute linear or rotary position measurement for challenging applications in complex product designs.

Based on innovative resonant inductive position sensing technology, CambridgeIC’s position sensors use designs integrated into conventional PCBs to measure linear position. This gives an accurate sensor which has low integration costs, is stable over time and extremely robust. Designers can provide absolute linear, 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. It is also tolerant of misalignments and wide measuring gaps. 

This makes CambridgeIC linear position sensors suitable for many applications, including linear actuators and float level sensors.

Deep integration for better cost/performance

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.
