Accelerometer Sensors
Overview
With the ability to simultaneously detect acceleration in 3 axial directions (X,Y, and Z) with a single chip, Hitachi Metals portfolio of highly sensitive and shock resistant accelerometer sensors are the world's smallest accelerometers and best featured accelerometer sensors available on the market today.

Key Features H34C
- Detect three axes (triaxial) simultaneously
- Very small and thin package: 3.4 x 3.7 x .92mm
- Single supply voltage of +2.2 to +3.6V
- Very low power consumption and standby
- Operation current 0.36mA at 3V
- Stand by current 1 µ A max.
- "Freefall Detection": While outputs of each axis (X,Y,Z) are nearly zero g, the terminal to output flag signal is equipped as a standard specification.
- Capable to detect "Static(Tilt) and "Dynamic"
- acceleration and measurement range is +/-3g
- High shock durability (>5000g)
- Temperature sensor and a function to adjust the performance drifts due to different temperature integrated.
- High reliability accelerometer sensor due to the ceramic package, air tight seal and factory calibration.
- ROHS Compliant
- Low cost and high volume manufacturing (Tape and Reel) ready.
- Precise factory calibration - 100 % of the accelerometer is factory calibrated. As a result, customer side is free from re-calibration. No additional cost for re-calibration is required.
Key Features H30CD
- Detect three axes (triaxial) simultaneously
- Very small and thin package: 2.9 x 2.9x .92mm
- Single supply voltage of +2.2 to +3.6V (I/O interface 1.7V)
- I2C digital interface
- Very low power consumption and standby
- Operation current 0.27mA at 3V
- Stand by: less than 5uA (T=65°C), Shutdown: less than 1uA((T=65°C)
- "Intelligent Freefall Detection":
- For precise Freefall judgement, the new feature of axial uniformity in threshold level of ZeroG is applied.
- To avoid incorrect FreeFall judgement due to vertical vibration or rotation an algorithm can be applied.
- Capable to detect "Static(Tilt) and "Dynamic"
- High shock durability (>5000g)
- Temperature sensor capable of digital output.
- ROHS Compliant
- Low cost and high volume manufacturing (Tape and Reel) ready.
- Precise factory calibration - 100 % of the accelerometer is factory calibrated. As a result, customer side is free from re-calibration. No additional cost for re-calibration is required.
Direct Benefits of Triaxial Accelerometer
Applications And Reccomended Use - Accelerometer Sensor
Hard-Drive Protection
