170.0 × 12.0 mm Active Area · Field-Trimmable Linear Force Profile
The FA408 is a linear strip force sensing resistor engineered for touch slider bars, continuous liquid-level monitoring, and edge pinch detection. It can be field-trimmed to custom lengths without losing sensitivity.
Full mechanical, electrical, and environmental characteristics verified by factory quality inspection.
Standard analog conditioning topologies for converting variable resistance into calibrated microcontroller inputs.
Connect FA408 in series with a 10 kΩ pull-down resistor to an ADC pin. Simplest approach for touch detection and threshold triggering.
Place FA408 in the feedback path of an inverting op-amp. Output voltage scales directly linear with force.
