Magnetic Sensor & Coil parts and their functions
4 top-level parts · 4 parts in total · full bill of materials below
| # | Part | Qty | What it does |
|---|---|---|---|
| 1 | Copper Winding | 1× | Rectangular induction coil, 500–1000 turns enameled copper wire, wound to 1 × 2 inch dimensions |
| 2 | Bare PCB | 1× | Oscillator and demodulation circuit measures coil impedance change as magnetized note passes; high sensitivity (±5% detection) |
| 3 | SMD Passive (R/C/L) | 1× | Capacitors and resistors tune coil Q-factor for optimal denomination discrimination |
| 4 | Connector | 1× | Signal harness to control board ADC input |
