This force sensor is an ultra-thin, flexible printed circuit. The standard A201 force sensor is constructed of two layers of substrate (polyester) film. The high-temp model (HT201) is constructed of two layers of polyimide.<br /><br />On each layer, a conductive material (silver) is applied, followed by a layer of pressure-sensitive ink.<br /><br />Adhesive is then used to laminate the two layers of substrate together to form the force sensor.<br /><br />The active sensing area is defined by the silver circle on top of the pressure-sensitive ink. Silver extends from the sensing area to the connectors at the other end of the sensor, forming the conductive leads.<br /><br />A201 sensors are terminated with male square pins, allowing them to be easily incorporated into a circuit. The two outer pins of the connector are active and the center pin is inactive.<br /><br /><b> Features: </b><br /><br /> - better linearity<br />- measurement of higher loads<br />- stable output with respect to load area<br /><br /><b>Specification: </b><br /><br /> - <b>Physical Properties:</b><br />- Thickness: 0.008 in.
