Force Sensor Exhibits High Impact Resistance

(Alps Alpine Co., Ltd.)

Alps Alpine Co., Ltd. introduces the HSFPAR004A force sensor, which the company claims will enhances impact resistance while maintaining the industry’s smallest size and offers high linearity and high resolution. The sensor is viable for use in stylus pens and other input devices.


Features include a linearity of less than 2% FS), a resolution that allows it to detect force with less than 0.01N, a footprint measuring 2 mm x 1.6 mm x 0.66 mm (W×D×H), an impact resistance up to 55N, an operating life of 1,000,000 cycles, and reliable resistance to external magnetic and electric fields.

Hear the CEOs of Infosys & HPE discuss the current crisis and how it has accelerated the need for digital transformation for their clients. Connectivity at the Edge, right mix of hybrid cloud, ability to extract data faster than ever before… these are just some of the contributions that HPE and Infosys make to our clients’ digital transformation journey.


Improved impact resistance of the sensor is achieved with the extension of the actuator diameter of the sensing zone from 0.2 mm to 0.4 mm, while at the same time keeping the rounded peripheral edge to disperse impacts. Therefore, the breakage risk of the sensor in stylus pens is reduced in case the pen is unintentionally dropped. Besides its use in input devices, the sensor is suitable for industrial machines handling equipment and a range of diverse applications.
