Circular Soft Potentiometer (Ribbon Sensor)
Circular resistive ribbon sensor with a donut-shaped sensing region (55.96 mm OD, 35.63 mm ID) and nominal 10 kΩ across the outer leads. The center wiper floats when unpressed — use a ~100 kΩ pull-up.

One outer lead of the nominal 10K soft potentiometer. Adafruit says one side pin is connected to ground through a 10K series resistor for use.
Middle pin resistance changes relative to either outer lead depending on press position; read as the analogue output. Adafruit says it floats with no pressure.
Other outer lead of the nominal 10K soft potentiometer. Adafruit says the other side pin is connected to Vcc through a 10K series resistor for use.
| Pin | Position | Type | Function | Voltage |
|---|---|---|---|---|
| Outer lead A | passive | One outer lead of the nominal 10K soft potentiometer. Adafruit says one side pin is connected to ground through a 10K series resistor for use. | Use through 10K series resistor; do not connect directly to ground/power per Adafruit product page. | |
| Wiper / middle pin | analog | Middle pin resistance changes relative to either outer lead depending on press position; read as the analogue output. Adafruit says it floats with no pressure. | Analogue voltage ranges from about 1/3 Vcc to 2/3 Vcc in Adafruit suggested circuit. | |
| Outer lead B | power | Other outer lead of the nominal 10K soft potentiometer. Adafruit says the other side pin is connected to Vcc through a 10K series resistor for use. | Vcc may be 3V, 5V etc through 10K series resistor per Adafruit product page. |
