Abstract
Systems and/or methods are provided for a dual-channel inductive proximity sensor. The sensor can include a sensing element which includes a core having a first cavity and a second cavity, a first coil accommodated within the first cavity of the core, and a second coil housed within the second cavity of the core. Each coil can be independently driven by oscillators to generate respective magnetic fields. The magnetic fields can be monitored to determine whether detection of a target object occurs.
