New High-Accuracy MEMS Sensors with 10-Year Product Longevity

ST's New Sensors are ideal for Inclinometers, Stabilizers or Levelers in Cameras and Security Applications

STMicroelectronics is extending its commitment to drive advanced automation and the Industrial Internet of Things (IIoT) by adding new high-stability MEMS sensors with 10-year product-longevity assurance.

Click for Larger Image - New High-Accuracy MEMS Sensors with 10-Year Product Longevity from STMicroelectronics The new sensors, to be made available during 2018, begin with the IIS3DHHC, a 3-axis accelerometer optimized for high measurement resolution and stability to ensure accuracy over time and temperature. The IIS3DHHC targets precision inclinometers in antenna-positioning mechanisms for communication systems, Structural Health Monitoring (SHM) equipment for keeping buildings and bridges safe, and stabilizers or levelers for a wide variety of industrial platforms. Its long-term accuracy and robustness are also ideal for high-sensitivity tilt and security sensors, as well as image stabilization in high-end Digital Still Cameras (DSCs).

ST’s 10-year longevity commitment assures long-term availability of a wide range of high-performing components used in industrial equipment, helping vendors handle the typically long in-market lifetimes of their products and extended operation in challenging environmental conditions. In addition to industrial sensors, the program covers STM32 microcontrollers, motor drivers, analog components, power converters, LEDs, and existing MEMS sensors that will be supported for at least 10 years.

“These high-quality industrial sensors leverage our investments in MEMS design and high-yield fabrication processes to deliver superior performance with low ownership costs for applications where the highest precision, repeatability, and robustness are critical,” said Andrea Onetti, Group VP and General Manager, MEMS Sensors Division, STMicroelectronics. “We will continue to introduce new types of precision sensors for industrial applications in the coming months, covered by our 10-year longevity commitment, including combination sensors, specialized sensors, and complete inertial modules.”
