Automotive manufacturing becomes an emerging market for sensors


At present, in addition to the demand for sensors for various types of electronic information products, automotive products and manufacturing equipment products have become emerging demand fields for global sensors.

Emerging market demand highlights

Magnetic sensors, position sensors and angle sensors are the most demanding sensors in the global market.

In automotive sensors, more secure sensors are the mainstream of market demand. Among them, fuel injection sensors, combustion detection sensors, and oil pressure/combustion pressure detection sensors used in automobile engines are most often equipped. In addition, in order to further consolidate the safety of automotive products, ABS running sensors and infrared sensors for keyless input must also be equipped.

In automotive sensors, thermistor products are indispensable for the internal temperature management of automotive products. Among them, in terms of the Japanese market alone, in 2003, the production of global thermistor products including NTC/PTC increased by 8% compared with 2002.

With the further increase in the global market demand for digital portable products and digital home appliances based on mobile phone products, the global market sales of thermistor products will also show significant growth in the future.

Temperature sensors are most often used. Among them, the NTC thermistor products have the most extensive application in the global market. NTC thermistors usually have resistance values ​​in the temperature range of 0°C to 30°C (500°C for high temperatures). The change, therefore, its functional characteristics can be applied to temperature compensation applications and temperature sensors.

Recently, the use of NTC thermistor products in the world has seen a significant increase in the use of mobile phone products, TCXO products and battery pack products. Among them, the 1.0mm x 0.5mm NTC thermistor product is the current mainstream demand in the global market. In addition, the more compact size of 0.6mm x 0.3mm NTC thermistor products has begun mass production. At the same time, 0.4mm x 0.2mm NTC thermistor products have also been successfully developed.

Nowadays, emerging applications for global thermistor products are thermal countermeasures for solving HDD products and temperature compensation for light sensing of LCD/CD products and DVD products.

At present, with the rapid growth of the global demand for DSC products, it becomes more important to perform optical correction of lens changes based on thermal effects, which requires the use of more CCD image sensor products, battery pack products, and flashlights. Products such as a variety of thermistor products.

High-tech attention

What is more noteworthy is that the development of global sensor high-skilled technology is increasingly attracting the attention of various manufacturers around the world.

At present, MEMS technology has been widely used in the development of various types of sensors around the world. For example, pressure sensors and angular velocity sensors will use MEMS technology to develop new products.

In addition to this, fingerprint authentication sensors, as a new product, have also been increasingly concerned by various industries around the world.

Fingerprint identification authentication sensors can be divided into regional products and scanning products. Among them, the regional products have smaller area for fingerprint identification than scanning products, which may lead to false recognition. Therefore, the global market demand for regional products is less than that of scanning products.

All in all, sensors with high sensitivity, high reliability, impact resistance, and adaptability to various environments (temperature, humidity, etc.), high security, etc., will be the focus of future global product development and global sensors. Hot market demand for products.
