ASC 4421MF Capacitive accelerometer aluminium housing

Lightweight uniaxial MEMS accelerometer in anodized aluminum housing for NVH and ride comfort testing


Key features

  • Anodized aluminum housing, IP67 protection
  • Lightweight design (10 g without cable)
  • ±2 g to ±200 g measurement range
  • Wide frequency response up to 7 kHz
  • Differential analog output ±2.7 V FSO
  • Shock resistance up to 6,000 g

Performance highlights

The ASC 4421MF is a uniaxial MEMS capacitive accelerometer optimized for NVH and vehicle testing applications. With a lightweight anodized aluminum housing and IP67 protection, it combines robustness with minimal mass, making it suitable for applications where low sensor weight is critical. The sensor provides a wide frequency response (DC to 7 kHz, ±3 dB), very low noise density, and operates with 5–40 VDC supply.

Usage conditions

Thanks to its low weight and durable anodized aluminum enclosure, the ASC 4421MF is ideal for test benches, ride comfort measurements, and mobile setups where easy mounting is required. The sensor withstands shocks up to 6,000 g and operates reliably in environments from −40 to +125 °C.

Applications

  • NVH (Noise, Vibration, Harshness) measurements
  • Driving comfort evaluation
  • Vehicle dynamics testing
  • Test bench and prototype validation
  • Road load data acquisition

Advantages of choosing this product

The ASC 4421MF provides a unique combination of lightweight construction and high accuracy, reducing mass influence on sensitive measurements. Custom cable lengths and connector options ensure flexible integration.
