Inductive sensor AFEs
Position detection of conductive targets with contactless magnet-free sensing
Achieve sub-micron resolution in position sensing applications with inductive sensor analog-front-ends (AFEs) and inductance-to-digital (LDC) converters that are immune to direct current (DC) magnetic fields and do not require magnets for operation. Our inductive sensor AFEs are reliable in harsh environments because of their contactless nature.
Design reliable contactless buttons that operate underwater and other harsh environments and in the presence of gloves with our inductive sensor AFEs offering high-accuracy and configurable force detection.
Implement reliable, simple solutions for incremental encoder knobs and event counting of up to 300 events per second with our inductive sensor AFEs.

Inductive sensor AFE design & development tools
16-button keypad made from a single piece of 0.6-mm thick stainless steel metal.
An inductive sensing based incremental encoder knob design can provide a robust and low-cost interface for control inputs. It can reliably operate in environments that have dirt, moisture or oil which can cause issues for alternate sensing technologies. This solution requires no magnets.
With 19 unique types of PCB coils that range from long rectangular asymmetric coils to small circular coils that are 3 mm in diameter, the LDCCOILEVM is designed to provide maximum flexibility for system prototyping allowing experimentation with different coil sizes
