## Description

A compact force sensitive resistor (FSR) from Interlink Electronics with a 4 mm (0.16″) diameter active sensing area. The resistance changes based on applied pressure — from over 1 MΩ with no pressure down to approximately 2.5 kΩ at full force — making it easy to detect touch, squeeze, and weight in your projects. The two pins have standard 0.1″ pitch spacing, so the sensor plugs directly into a breadboard for quick prototyping. While not precise enough for accurate weight measurement, FSRs are excellent for detecting the presence and relative intensity of pressure. Key Features 4 mm Active Area – Compact circular sensing surface Variable Resistance – >1 MΩ (no pressure) to ~2.5 kΩ (full pressure) Breadboard Friendly – 0.1″ pitch pins for easy prototyping Simple Interface – Works as a variable resistor in a voltage divider circuit Specifications Sensing Area – 4 mm (0.16″) diameter Resistance Range – >1 MΩ (no force) to ~2.5 kΩ (full force) Pin Pitch – 0.1″ (2.54 mm) Manufacturer – Interlink Electronics Ideal For Touch and squeeze detection in interactive projects Pressure-sensitive triggers and inputs Wearable electronics and soft robotics Arduino and microcontroller sensor projects Note: FSRs are great for detecting relative pressure but are not suitable for precise weight measurement.

**Product Type:** physical
