The FSR 406 model is a single-zone Force Sensing Resistor optimized for use in human touch control of electronic devices such as automotive electronics, medical systems, and in industrial and robotics applications. FSRs are two-wire devices. They are robust polymer thick film (PTF) sensors that exhibit a decrease in resistance that corresponds inversely with increase in force applied to the surface of the sensor. It has a 39.6mm square active area and is available with one of four connection options.

Features:

• Actuation force as low as 0.1N and sensitivity range to 10N
• Easily customizable to a wide range of sizes
• Highly repeatable force reading; as low as 2% of initial reading with repeatable actuation system
• Cost effective
• Ultra thin; 0.45 mm
• Robust; up to 10 million actuations
• TTL compatible and optically isolated input.
• Simple and easy to integrate

Application:

• Detect and qualify press - Sense whether a touch is accidental or intended by reading force
• Use force for UI feedback - Detect more or less user force to make a more intuitive interface
• Enhance tool safety - Differentiate a grip from a touch as a safety lock
• Find centroid of force - Use multiple sensors to determine centroid of force
• Detect presence, position, or motion - Of a person or patient in a bed, chair, or medical device
• Detect liquid blockage - Detect tube or pump occlusion or blockage by measuring back pressure
• Detect proper tube positioning
• Many other force measurement applications

Package Includes:

• 1 x FSR 406 39.6mm Square Force Sensing Resistor - Premium
