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.
Interactive touch buttons
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.
Event counting
Implement reliable, simple solutions for incremental encoder knobs and event counting of up to 300 events per second with our inductive sensor AFEs.
Metal proximity detection
Detect the presence of conductive materials with micrometer precision with our inductive sensor AFEs in proximity or position sensing applications.
