Ultra-thin Linear Flexible Potentiometer (300mm, IP67, Arduino / ESP32 / Raspberry Pi Compatible)

This linear flexible potentiometer leverages graphene pressure-sensitive technology to deliver high-precision position detection within an ultra-thin, conformable form factor. Built on a flexible film substrate measuring just 0.45mm thick, this sensor outputs analog voltage signals that correspond precisely to the pressed location in real-time. The integration of optimized internal circuitry and a pre-installed 300mm silicone wire eliminates complex wiring requirements, making this potentiometer an ideal solution for interactive applications ranging from smart switches to multimedia interfaces where traditional rigid sensors cannot conform to curved or irregular surfaces.

Flexible Architecture Meets Precision Detection

The graphene-based pressure-sensitive material achieves position detection accuracy of ±2mm across the entire 300mm sensing length, while the 0.45mm thickness allows the sensor to bend and conform to curved surfaces without compromising measurement integrity. The sub-1ms response time ensures that even rapid positional changes are captured with minimal latency, enabling the sensor to output continuous, linear position signals that directly translate physical displacement into actionable electrical data. This combination of flexibility and precision eliminates the trade-off typically encountered in traditional potentiometers, where mechanical rigidity is necessary for accurate readings.

Streamlined Integration with Open-Source Platforms

This flexible potentiometer requires only three pins for full operation, providing an intuitive analog output that integrates seamlessly with Arduino, ESP32, and Raspberry Pi platforms. Position data is accessed through standard analog-to-digital conversion, eliminating the need for specialized drivers or complex communication protocols. The pre-installed 300mm silicone wire with standard connector further accelerates prototyping cycles, allowing developers to move from concept to functional validation in minutes rather than hours.

Industrial-Grade Durability in Flexible Form

The IP67-rated sensor assembly withstands water immersion and dust ingress while maintaining operational integrity through over 1 million press cycles. The pre-applied double-sided adhesive backing enables secure mounting on diverse substrates without additional fasteners or adhesives, while the low actuation force range of 20-50g ensures comfortable user interaction without premature wear. This durability profile makes this flexible potentiometer suitable for deployment in moisture-prone environments and high-frequency interaction scenarios where maintenance access is limited or costly.
