Low-Power capacitive MEMS vibration sensor ASC ECO-x311

Compact analog MEMS acceleration sensor with voltage output for battery-powered systems and structural health monitoring

Key features

Analog differential voltage output: ±2.4 V
Measuring ranges: ±2 g to ±40 g
Extremely low power consumption (<250 µA)
DC response with bandwidth up to 2.4 kHz
Lightweight IP68 aluminum housing
Available in 1, 2, or 3-axis configurations
Shock resistance up to 10,000 g

Performance

The ASC ECO-x311 is an ultra-efficient capacitive MEMS acceleration sensor optimized for applications that require low energy usage, high durability, and a compact footprint. With an analog differential voltage output and DC to 2.4 kHz bandwidth, this sensor ensures stable signal response for both static and dynamic measurements.

Its extremely low current consumption of <250 µA makes it ideal for battery-powered or energy-harvesting systems, such as AGVs, mobile platforms, autonomous monitoring units, or wireless sensor nodes. The robust, IP68-rated aluminum housing allows use in harsh or humid environments without compromising signal integrity.

Operating conditions

The ECO-x311 functions reliably from -20 °C to +125 °C, with options down to -40 °C. It can withstand shock loads of up to 10,000 g, and is available with a 6 m PUR cable, customizable in length or connector type. Its flat profile and lightweight design allow seamless integration into embedded and space-constrained installations.

Applications

Battery-powered or wireless monitoring systems
Mobile robotics, AGVs, drones
Structural health monitoring of infrastructure
Predictive maintenance in off-grid locations
Vibration measurement in compact machinery
