Resonant inductive sensing is well suited to measuring the angle of dials, in a user interface or performing another function in a machine.

Using CambridgeIC's solution means no contact between sensor and targets and the dials and readers may be housed in separate modules.  So, for example, a fixed reader can read multiple sets of dials as they move round a production process, and each set of dials can be read by multiple readers at different points in the process.

• Rotary sensors read dial angles
• Large gaps possible (11mm with 50mm rotary sensor)
• Tolerant to radial misalignment (2mm with 50mm rotary sensor)
• Up to 24 settings per dial for a robust system
• A single CAM204 chip supports up to 4 dials (or 16 with external mux components)
• Immune to dirt and moisture
• Simple and robust
