PMMA 951LT is a motion sensor, also known as an accelerometer, developed and produced by NXP Semiconductors. It is specially designed for motion detection applications, such as automotive, consumer, industrial, and medical.

The PMMA 951LT accelerometer features a double-sided MEMS sensing element, housed in a package measuring 8mm x 3mm. It offers low-voltage operation from 2.5 V to 3.6 V, and a wide dynamic range of up to ±20g. The sensor allows for operation over a temperature range of -20°C to +105°C and is highly resistant to the effects of shock and vibration. The PMMA 951LT is a single-axis motion sensor.

The working principle of the PMMA 951LT is based on piezoelectric effect. When the sensor is subject to physical motion or stress, two thin plates inside the device experience compression. This results in a piezoelectric effect, where the plates experience a change in their electrical properties that the sensor captures, processes, and sends to the user.

The PMMA 9551LT has a wide range of applications, including vibration sensors for condition-based monitoring, motion sensors for consumer electronics, automotive accelerometers for occupant detection, and industrial accelerometers for tilt sensing. The sensor is highly suitable for use in challenging high-temperature environments as well as in low-current applications such as portable consumer electronics.

The PMMA 951LT accelerometer is an excellent choice for detecting acceleration, orientation, and vibration. It offers high accuracy, low-voltage operation, wide dynamic range, and excellent shock and vibration resistance. Additionally, the sensor offers superior performance over a wide temperature range, making it the ideal choice for applications in harsh and challenging environments.
