Alps Alpine added the HSFPAR007A Force Sensor, the company's smallest, to its HSFPAR Series of force sensors. The sensor fits into the tip of a stylus pen for tablet PCs, to enable accurate reproduction of drawing thickness corresponding to the pressure applied. Achieving high sensitivity, high resolution and high linearity, as well as outstanding impact resistance.
The HSFPAR007A Force Sensor has a footprint of 40% of the HSFPAR004A, while retaining the basic performance capabilities of the earlier product. The new product is small enough to fit in the slimmer stylus pens used for smartphones, both enhancing flexibility in design and helping to improve user-friendliness of drawing applications.
The sensor detects stress as light as 0.01N, enabling applications in robot arms and other parts of industrial equipment handling precision devices.
The product has a wide range of potential uses as a sensor for detecting force along the Z axis. For example, it can be embedded beneath a touch panel or capacitive sensor to detect force applied to the operating surface and even ascertain whether an input operation was intentional or a mistake. Features include a high sensitivity and linearity (2% FS), an operating life of 1 million cycles, and a structure unaffected by external magnetic or electric fields.
