1 Introduction ( FULL TECHNICAL DATA SHEET ON REQUEST )
The AC-SMA-XXD series accelerometer is a single-axis capacitive MEMS accelerometer, consisting of a fully silicon MEMS sensing structure and a low-power signal processing ASIC composition. AC-SMA-XXD is powered by a single power supply (5V) and features low typical power consumption (11mA). Its output is either a digital signal in SPI protocol or a fully differential analog signal (common mode voltage at 2.5V), and the analog output voltage ranges from 0.5V to 4.5V. Product packaging The product is packaged in a standard LCC20 ceramic package with a total of 20 pins. The precise dimensions of the external shape are provided in the image below. The final product quality is 0.60±0.02 Gram.
Notes:
- Long-term repeatability: Accelerometers with a range of 32 ± 50g have undergone long-term repeatability testing, and test data spanning 1.5 years is available. The proportion of accelerometers with zero-bias repeatability < 0.2mg is 31%, the proportion with zero-bias repeatability < 0.5mg is 75%, the proportion with zero-bias repeatability < 1.2mg is 100%, the proportion of accelerometers with scale factor repeatability < 100ppm is 93.7%, and the proportion with scale factor repeatability < 200ppm is 100%.
- The smaller the measurement range, the higher the accuracy. For example, products with a ±2g measurement range have the best zero-bias stability indicator of 3μg, and also exhibit better long-term repeatability.
The ACM-100 tri-axis accelerometer is a widely used acceleration sensor series products produced by Micro-Magic Inc with Swiss patented technology, which can be used in various fields such as vibration testing and impact testing. The product adopts digital interface output, with RS232, RS485, TTL, Modbus protocol, and RS422 optional. Different address codes can be set, and multiple sensors can be connected in series for long-distance measurement and data analysis at multiple points. ACM-100 is a single crystal silicon capacitive sensor, consisting of a silicon chip that has undergone micro mechanical processing, a low-power ASIC for signal adjustment, a microprocessor for storing compensation values, and a temperature sensor.
The product has a small size, low power consumption, calibrated, fixed structure, and stable output. The new electronic configuration provides solid-state power for reset and comprehensive protection against overvoltage. The long-term stability and typical deviation of the proportional factor within the full range are less than 0.1%. This series of products has the characteristics of fixed structure, low power consumption, and excellent deviation stability, ensuring outstanding output reliability.
Product Overview
The ACM-1700 series is a high-performance single axis MEMS accelerometer designed specifically for high-precision and high reliability acceleration measurement applications. This series offers four different range models, covering a wide measurement range of ±10g to ±200g, and supports customization according to customer needs. The sensor adopts 24 bit binary complement data output and communicates through SPI digital interface to ensure stable and accurate data acquisition even under complex working conditions.
