The FSR410 25.42mm Round Force Sensing Resistor is a rugged, flexible, thin-film polymer component specifically engineered to deliver reliable tactile force data. Unlike rigid load cells or strain gauges that require bulky mechanical frames and precise physical alignment, this FSR is entirely flat. It operates on a robust shunt-mode principle: compressing the sensor forces micro-conductive particles inside the polymer film into closer contact, creating a measurable drop in resistance across its output leads.

With a generous 25.42 mm active sensing window, the FSR410 provides an excellent contact surface for human finger presses, foot placement tracking, or generic mechanical actuators. The sensor features a wide dynamic triggering threshold, registerable from an ultra-light 30 grams up to a firm 10 kilograms. It is highly resilient, capable of enduring millions of compression cycles without material fatigue, making it perfect for custom control panels, medical devices, and robotic grip arrays.

Key Features & Benefits:

• Wide Dynamic Response Range: Faithfully scales its analog output across a vast sensing range from 30g to 10kg, handling everything from light touch interactions to heavy mechanical loads.

• Ultra-Thin & Adaptable: At less than 0.5mm thick, the flexible backing material easily adheres to flat or slightly curved surfaces using simple double-sided adhesive sheets.

• Straightforward Circuit Integration: Converts physical pressure into an easily readable analog voltage curve using a simple voltage divider circuit paired with an external fixed resistor.

• Industry-Standard Pin Spacing: Features a flexible connection tail terminated with dual male pins spaced at a standard 2.54mm (0.1") pitch, making it fully compatible with breadboards and header sockets.
