【Ferromagnetic Material Magnetic Resistance Element】 MR Sensor A sensor that utilizes the magnetic resistance effect of ferromagnetic materials, where the resistance value changes according to the magnetic field strength. It has sensitivity in low magnetic fields, a wide operating temperature range, excellent frequency characteristics, and can be used in harsh environments where optical methods are difficult. A high-resistance type MR that takes advantage of the benefits of magnetic resistance elements is also available in the lineup. 【Semiconductor Pressure Sensor】 A pressure sensor for medium pressure ranges that utilizes the semiconductor piezoelectric effect. It is available in a lineup of ultra-compact packages that can accommodate small casings, including SMD terminal types that allow for automatic mounting. Notably, it features a higher breakdown pressure compared to other companies' sensors. 【Water Level Sensor】 Developed as a water level detection sensor for water heaters. This sensor can detect water levels of tap water, hot water, etc., as well as water pressure. Utilizing a semiconductor pressure sensor, it offers excellent output stability and is more resistant to impact pressure, such as water hammer, compared to other companies' sensors.
