Devices Solutions

Micro batteries serve as power sources for small devices such as wristwatches, and as backup power for essential features such as memory and clock functions in security cameras, car dashcams, etc. Reflow-compatible products* allow for automatic installation on circuit boards, which contributes to shorter manufacturing lead times and more stable quality.

※ Reflow-Compatible Products: Reflow is a soldering method used when mounting electronic components on a circuit board. It involves melting pre-applied solder at room temperature to attach the components. Reflow-compatible products are specifically designed to accommodate this soldering method.

Complex electronic devices such as smartphones contain many parts, and a reference signal is needed to synchronize these multiple components. This is one key to keeping the device operating smoothly. Seiko provides high-precision quartz crystal oscillators that generate these essential reference signals, as well as making ICs for crystal oscillators. These unseen technologies underlie almost everything in our daily lives.

We make infrared sensors capable of detecting and measuring small temperature fluctuations by sensing the infrared radiation emitted by objects, including people. Seiko's infrared sensor modules are used in hundreds of everyday applications, such as adjusting the output of air conditioners or the heating time for microwave ovens. In fact, these small, high-precision, non-contact infrared sensor modules play a crucial role in a wide variety of fields. They are often integrated into disaster monitoring equipment, security equipment, and other devices that require accurate, non-contact temperature measurement.

High-function metals, which take advantage of properties such as high strength and corrosion resistance, find applications as diverse as watch springs, industrial valves, and medical instruments.
Rare-earth magnets* are heat-resistant and strongly magnetic even in small sizes, such as 1 mm or less. They are widely used in applications such as magnetic sensors in automobiles.
Seiko uses its expertise in metal materials gained from over a century of watchmaking to contribute to a multitude of product areas, including automotive, medical, and electronic devices.

※ Rare Earth Magnets: Permanent magnets made from rare earth materials. There are two types: neodymium magnets and samarium-cobalt magnets. They are characterized by strong magnetic force and high coercivity, which allows them to retain their magnetism effectively.

We provide precision machined components for critical automotive parts such as engines and brakes, supporting both the performance and safety of vehicles. We also supply components for hard disk motors and small-diameter ball bearings for compact fan motors, thus contributing to the rapid expansion of Information and Communication Technology (ICT).

Drawing upon the precision manufacturing expertise we developed through more than a century of watchmaking, Seiko manufactures internal grinding machines that achieve micron-level processing accuracy. By integrating image processing and precision assembly techniques, we provide automated, labor-saving equipment that adds high value to manufacturing processes.

Seiko's portable thermal printers hold the No.1 domestic market share* for mobile printers used for mobile payments, such as payments for courier deliveries. These devices are compatible with a variety of payment systems and point-of-sale applications, which helps our clients improve their customer experience and facilitate store operations.
