Munich, September 3, 2018 – Seiko Epson Corporation (TSE: 6724, “Epson”) has developed a new high-performance three-axis 
accelerometer, the M-A352. Samples will begin shipping at the end of 2018, with volume production scheduled for the spring of 2019.
Epson’s accelerometers, first launched in 2014, have been used in an array of applications, earning an excellent reputation for outstanding performance and quality. Aging social infrastructure and the soaring cost of infrastructure maintenance, monitoring, and renewal are recognized as serious problems for nations and communities. This recognition is driving a growing need for technology to monitor the health of structures using sensors.
Epson developed the new M-A352 to give momentum to the spread of serious structure health monitoring technology. The M-A352 provides the necessary noise performance of 1 µG/√Hz or better (servo accelerometer*1 class) along with outstanding durability and manufacturability, ensuring stable supply and cost competitiveness. Offering a rare combination of excellent accuracy and high durability, the M-A352 can be used for applications where high-accuracy measurements were formerly difficult to take.
This accelerometer can be used in structure health monitoring (e.g., of buildings, roadway structures, bridges, tunnels, and steel towers), earthquake detection, environmental vibration measurement, industrial equipment monitoring, unmanned vehicles (e.g., terrestrial vehicles, undersea probes), and the measurement of the vibration and path of industrial equipment and vehicles.
