Electronic Components

Contributing to the compactness, low power consumption,
and high functionality of Devices Solutions
The precision electronic components that emerged from our years-long development of quartz watches are now widely used in smartphones, cars, digital appliances, and industrial equipment. For example, rechargeable batteries and capacitors play a vital role in communications as the backup power supply for the memory and clock functions of digital equipment. Our quartz crystals and quartz oscillator ICs generate reference signals to synchronize multiple electronic components, while our infrared sensor modules are key components in security devices and home appliances as well as in contactless thermometers. All these components were created through our long history of innovation.

Infrared sensor modules

Superior Performance Co-Ni Alloy Products and Rare Earth Magnets

Infrared sensor modules
With their ability to measure the temperature of both people and objects, these components enable a variety of functions such as adjusting the output of air conditioners and adjusting the heating time of microwave ovens, making them indispensable in daily life. Our infrared sensors are widely used in a variety of applications, including disaster-prevention monitoring equipment, security devices, and non-contact thermometers.

Quartz crystals and quartz oscillator ICs
Devices Solutions are essentially a collection of multiple parts, and quartz crystals are the key to synchronizing all of those parts through reference signals so that these devices can operate properly. Just as one example, quartz crystals generate reference signals in smartphones, among many other types of Devices Solutions, without which they would lose functionality. Seiko is proud to offer extremely high-precision quartz crystals and quartz oscillator ICs that keep billions of devices running smoothly all over the planet.

Superior Performance Co-Ni Alloy Products and Rare Earth Magnets
Because of properties such as high elasticity and high corrosion resistance, Superior Performance Co-Ni Alloy Products (SPRON) are widely used for applications such as watch springs, industrial valves, and medical equipment. Rare earth magnets (DIANET) also possess excellent corrosion resistance as well as heat tolerance, and are used in a wide range of applications, including magnetic sensors and in-vehicle components.

Micro batteries and capacitors
Our micro-batteries are used as a power source for watches and many other devices. They are also used as a backup power supply for the memory and clock functions of digital devices such as surveillance cameras and dashcams. Our reflow-compatible products enable automatic mounting on circuit boards, contributing to shorter manufacturing lead times and more consistent quality.

Precision Parts & Machines

Supporting industry with
high-precision processing technologies born from watchmaking
We supply high-precision parts that are used in components for automobiles, hard disk drives, and miniature ball bearings. The machine tools that we have produced for bearing makers, automotive parts makers, and many other types of manufacturers are proving their worth daily in high-precision manufacturing.
Main businesses, products, and services

High-precision processed parts
We provide high-quality, highly reliable automotive ABS brake parts and engine parts, motor parts for hard disk drives, and miniature ball bearings for devices such as miniature fan motors, which will be increasingly in demand due to the ongoing implementation of ICT and IoT.

Machine tools and factory automation
Based on the precision technologies that we have cultivated through watchmaking, we manufacture internal grinders that enable high-precision, high-speed processing, even on a micron level. In addition, by combining image processing with precision assembly technology, we provide automation and labor-saving equipment to bring high added value to our customers’ manufacturing processes.

Printing devices

Meeting diverse printing needs with reliable technical capabilities
Our thermal printers are compact, extremely quiet, and easy to maintain. Because of these features, they are widely used in devices such as POS cash registers and other kinds of payment terminals, medical equipment, and measuring instruments. Our inkjet printheads are key components of industrial inkjet printers. They contribute greatly to improved productivity and higher-quality printing for products such as advertising billboards, building materials, and textiles, among many others.
Main businesses, products, and services

Thermal printers
Because of the rapid expansion of mobile payment terminals, mobile POS terminals, and home delivery certification terminals, miniature thermal printers are becoming more indispensable than ever, and Seiko holds the top share in the global market for mobile printers. Our printers can be used with various payment systems and cash register apps. They not only improve overall customer experience, but also help store management.

Inkjet printheads
Our inkjet printheads, which apply microscopic droplets of ink onto printing surfaces, make use of our precision processing technology. From advertising billboards that can be seen around town to building materials and textile printing, our printheads are seeing increasing use in a wide range of areas.
