FSLP Sensor Data Sheet Force Sensing Linear Potentiometer FSLP Sensor for Position and Force Applications Description Features and Benefits The Force Sensing Linear Potentiometer (FSLP) Sensor is Interlinks solution for Rugged design - Over 1M touch capturing position and force simultaneously in compact applications. The sensors tough, moisture resistant surface can be used with a finger, stylus, or glove even in activations over entire sensor area with harsh environments. no degradation observed. Measures position along a circular path The Force Sensing Linear Potentiometer (FSLP) simplifies input design, saves critical Easy to integrate rroooomm,, aanndd hheellppss ssaavvee bbaatttteerryy lliiffee..

Force dependent on actuation interface, mechanics, and measurement electronics. **Performance values are for the force sensing portion of the sensor. The position sensing component is minimally affected by environmental and durability factors.
