About the ASC 5421MF Capacitive Accelerometer

The accelerometers of type ASC 5421MF and ASC 5425MF 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 5421MF features a lightweight aluminum housing and the sensor ASC 5425MF provides a robust stainless-steel housing, both with protection class IP65 and an integrated cable with configurable length and connectors.

The triaxial accelerometers enable the detection of smallest accelerations over a wide frequency response range in three degrees of freedom, e.g. for test bench applications, vehicle and road monitoring as well as resonance and flutter tests in aviation.
