Small Size, High Resolution and High Linearity Ideal for Use in Style Pens
TOKYO, March 28, 2019 – Alps Alpine Co., Ltd., (Tokyo: 6770; CEO: Toshihiro Kuriyama), a manufacturer of high-quality electronic products, has added the HSFPAR004A Force Sensor to its lineup. The sensor enhances impact resistance while maintaining the industry’s smallest size*1 and offers high linearity and high resolution, which makes it ideal for use in stylus pens and other input devices.
The HSFPAR004A maintains the features of already existing products for high linearity (<2%FS), high resolution (detects micro force with less than 0.01 N), and small size of 2.00 mm × 1.60 mm × 0.66 mm (W×D×H), while at the same time realizing an improvement in impact resistance of up to 55 N. The sensor offers an operating life of 1,000,000 cycles and is resistant to external magnetic and electric fields.
The improved impact resistance of the sensor is achieved with the extension of the actuator diameter of the sensing zone*2 from the existing 0.20 mm to the new 0.40 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, while still guaranteeing smooth pen pressure expression without spoiling the easy integration into end products. Besides its use in input devices, the sensor is suitable for industrial machines handling precision equipment and a range of diverse applications, especially on the grip parts of robot arms for precision grip force adjustments.
