Position detection of conductive targets with contactless magnet-free sensing

parametric-filter檢視所有產品
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. The contactless nature of our inductive sensor AFEs allow them to remain reliable in harsh environments.
