4.5 inch Flex Sensor Spectra Symbol Resistive

The 4.5 inch Flex Sensor Spectra Symbol Resistive is a flexible, resistive sensor designed to measure the amount of bend or flex applied to its surface. As the sensor is bent, its resistance increases in proportion to the bend radius. It is equipped with a 0.1-inch spaced breadboard-friendly connector, making it highly compatible with a wide range of microcontroller projects.

This bend sensor is widely used in applications like robotic arms, wearable medical devices, physical therapy systems, gaming controllers, and musical instruments. Its low profile, lightweight design, and high durability (over 1 million life cycles) make it a trusted choice for professionals, students, and innovators.

Engineered with precision and simplicity, this sensor features a flat resistance of 10K Ohms and a bend resistance range of 60K to 110K Ohms depending on the degree of flex. It operates efficiently within a temperature range of -35°C to +80°C and has a continuous power rating of 0.5 Watts.

Whether you’re developing gesture-based interfaces, building exoskeleton suits, or creating interactive gaming gear, the 4.5 inch Flex Sensor Spectra Symbol Resistive offers reliable performance with easy integration.
