SEN0690 300mm Flexible Linear Potentiometer

Add a slim linear touch input to curved or space-constrained surfaces with this flexible ribbon-style potentiometer. At just 0.45mm thick, it can conform to wearables, curved dashboards, soft robotics and other builds where a bulky mechanical slider is not practical.

The graphene-based pressure-sensitive film provides continuous analogue position output across a 300mm sensing length, with typical ±2mm accuracy and a response time under 1ms. It uses a simple three-pin analogue interface, making it straightforward to read from Arduino, ESP32 and Raspberry Pi projects via analogue-to-digital conversion.

The sensor assembly is rated IP67 for water and dust resistance, and is designed for more than 1 million normal flexible press cycles. A pre-installed 300mm silicone wire and double-sided adhesive backing help speed up mounting and prototyping.

Supplied as one linear flexible potentiometer.
