Uniaxial accelerometer ASC 4421MF

MEMScapacitiveflat

Overview
The ASC 4421MF is a uniaxial MEMS capacitive accelerometer designed for medium-frequency NVH, test-bench and vehicle dynamics measurements. It delivers a differential analog voltage output and supports a wide range of measurement spans.

Key features

• Sensor technology: MEMS capacitive
• Number of sensitive directions: Uniaxial
• Output signal: Differential analog voltage (±2.7 V FSO)
• Measurement ranges available: 2 g, 5 g, 10 g, 30 g, 50 g, 100 g, 200 g
• Power supply: 5 to 40 VDC

Technology
ASC 4421MF sensors use proven MEMS capacitive technology with integrated signal conditioning to provide a stable differential analog output. The MF (Medium-Frequency) variant offers an extended usable frequency band and is engineered for high shock resistance and reliable operation across a wide temperature range.

Housing
The sensor is housed in a lightweight aluminum enclosure with protection class IP67. An integrated cable is provided with configurable lengths and connector options to suit bench or in-vehicle installations. The flat design facilitates quick, space-efficient mounting.

Applications
Suitable for NVH analysis, test bench measurements, vehicle dynamics and comfort assessment, prototype testing and laboratory measurement setups where a rugged medium-frequency uniaxial accelerometer is required.
