Product Overview
JSAM2S0 accelerometer is a MEMS variable capacitance acceleration sensor based on MEMS variable capacitance technology that can follow ultra-low frequency acceleration from 0 Hz. The sensor is made of 304 stainless steel in a monolithic structure, compact and lightweight (only 13g) for convenient mounting. An ultra-low current consumption of only 5mA makes it very energy efficient. The device is suitable for safety systems in vehicles, industrial equipment, consumer electronics, and other applications.

FAQ
Q: 1. What is the main benefit of the JSAM2S0's DC response (0Hz starting frequency)?
A: The ability to measure acceleration down to 0Hz allows the device to monitor constant or very slow accelerations, such as:
Static tilt angles in industrial equipment monitoring
Long-duration vibration shifts in structural health monitoring
Ultra-low frequency motion in automotive safety systems makes it suitable for applications in which traditional AC-coupled accelerometers would fail to detect very low-frequency signals.
Q: 2. In what way does the 304 stainless steel monolithic structure improve my application?
A: The single-piece 304 stainless steel construction gives:
Very good resistance to corrosion in harsh environments (humidity, chemicals)
Strong structure and minimal deformation of the housing for proper signal transfer
Great resistance to mechanical shock and vibration
EMI/RFI protection for stable performance in electrically noisy surroundings
Q: 3. What is the practical implication of the 5000g shock resistance?
A: The 5000g shock survival rating makes sure of:
Operation in situations with a strong impact (e.g., car crash tests, hammer mill monitoring)
Stability over a long period of time in cases of mechanical overload that occurs occasionally
Lower risk of damage while handling, installing, and working with the device
Q: 4. How will the 5mA low power consumption be of use to battery-powered systems?
Battery life will be greatly prolonged in portable/wireless monitoring setups, with the heat generated being very low as well, and the measurement can stay stable.
Low-power embedded systems and IoT devices will be compatible with the sensor.
Additional Technical Note
The 35-60 μg/√Hz noise density makes this sensor an ideal solution for applications that require the high-resolution measurement of very low-level vibrations while keeping an excellent signal-to-noise ratio over the whole frequency range (0-800Hz).
