About the ASC 4421MF Capacitive Accelerometer

The accelerometers of type ASC 4421MF and ASC 4425MF are based on proven MEMS technology and capacitive operating principle. The integrated electronic circuitry enables a differential analog voltage output (±2.7 V FSO) and flexible power supply voltage from 5 to 40 VDC. The MF (Medium Frequency) accelerometers from ASC provide a wide frequency response range from 0 Hz to 7 kHz (±3 dB) and an extremely robust design with shock resistance up to 6,000 g.

The sensor ASC 4421MF features a lightweight aluminum housing and the sensor ASC 4425MF provides a robust
stainless-steel housing, both with protection class IP67 and an integrated cable with configurable length and connectors.

The uniaxial accelerometers feature a flat design that allows quick and easy mounting, a basic requirement in NVH (noise, vibration, harshness) and test bench applications or for evaluating driving comfort and vehicle dynamics.
