Performance highlights ASC 4111LN MEMS capacitive accelerometer

The ASC 4111LN is a uniaxial MEMS capacitive accelerometer optimized for ultra-low noise and high signal integrity. With differential output of ±4 V FSO and a frequency response up to 2000 Hz (±5%), the sensor delivers exceptional resolution and thermal stability even in challenging environments.

Usage conditions

With a miniature design (weighing only 3g) and IP67-rated aluminum housing, the ASC 4111LN is built for harsh industrial settings and hard-to-access spaces. The sensor operates from -20°C to +80°C and supports supply voltages from 6 to 40 VDC. Mounting is adhesive-based.

Possible applications

• Operational stability testing in automotive and e-mobility
• Flutter testing in aerospace
• Structural analysis and monitoring
• Modal and fatigue analysis
• Compact and embedded test systems

Advantages of choosing this product

The ASC 4111LN excels in tight spaces where high-performance data acquisition is required. It combines rugged construction with precision MEMS technology and ultra-low noise, making it a top choice for structural and component-level testing.

Other important features

• Noise floor down to 7 µg/√Hz (±2g model)
• Frequency range (±3 dB): up to 4200 Hz
• Shock resistance: up to 5000 g
• Output impedance: 90 Ω
• 4-wire differential analog signal
