The world's thinnest permanent magnet movable linear vibration actuator with a thickness of 1.4mm.
"TapSense" has achieved a thickness of 1.4mm, making it the world's thinnest, by redesigning the magnetic circuit from scratch based on the "precision" manufacturing technology cultivated in the camera industry since our founding, using sophisticated and advanced small vibration motor technology optimized for thin designs. This enables further thinning of digital devices such as tablet PCs and laptops. The product not only reproduces a crisp click sensation with excellent responsiveness and vibration levels but also enables a variety of tactile feedback, such as dial operation feel. Additionally, due to its high responsiveness, it is easier to control compared to conventional linear vibration actuators. As of the end of March 2024, our group's cumulative shipments of vibration motors have exceeded 1.5 billion units, and the products created through lightweight, compact technology, high efficiency technology, and control technology have received high praise from customers. We will continue to propose innovative solutions that contribute to the creation of a comfortable society as a member of the world's No. 1 comprehensive motor manufacturer. *As of May 1, 2024, based on our research.

Applications/Examples of results
●Realization of mechanical feel during tap operations By employing an optimal magnetic circuit design and a spring & damper combination structure suitable for thin profiles, we achieve "vibration amount due to resonance," "sharp stopping performance," and "stabilization of vibration and stopping characteristics." It balances an ultra-thin 1.4mm with a realistic mechanical feel. The high-quality lateral force generated from horizontal vibrations (longitudinal waves) provides a diverse mechanical feedback sensation uniformly during operations such as tapping, swiping, scrolling, and flicking. Additionally, due to its high responsiveness, it is easier to control compared to conventional linear vibration actuators. *As of April 2024, according to our research. ●Possible expansion to various applications Achieving high performance with a vibration amount of 6.4Gp-p and a vibration duration of 12ms at a thickness of 1.4mm, "TapSense" is the world's thinnest (※) and enables further thinning of digital devices such as tablet PCs and laptops. Furthermore, with an operating temperature range of -40℃ to +85℃, it offers broad reliability, making it suitable for a wide range of devices including automotive panels and wearable medical devices.

Company information
Since its establishment in 1949, our company has been a top manufacturer of camera shutters, supporting Japan's camera industry, which leads the global market, while also working on business diversification and advancing to become a "comprehensive manufacturer of ultra-small and precision devices" covering everything from ultra-small components to system equipment. With the NIDEC Group unifying the brand and company name from Nidec to "Nidec," our company will also change its name from "Nidec Copal Corporation" to "Nidec Precision Corporation," incorporating the group brand name "Nidec." "Precision" signifies "accuracy," and we aim to extend the "precision" manufacturing techniques cultivated in the camera industry since our founding to various industries worldwide, responding to our customers' needs for miniaturization and lightweight products while adding new value, thereby contributing to society. With this "precision" manufacturing, we will focus all our corporate activities on providing technologies and products that are even more "helpful to our customers" and "satisfactory to our customers," striving to become our customers' "true business partner."
