Uniaxial accelerometer ASC 4425MF

MEMScapacitiveflat

Product
ASC 4425MF is a uniaxial analog accelerometer based on MEMS capacitive sensor technology. It delivers a differential analog voltage output (±2.7 V FSO) and accepts a supply voltage from 5 to 40 VDC, making it suitable for NVH and test-bench measurements that require medium-frequency response and high shock tolerance.

Sensor details

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

Technology
Sensors of type ASC 4425MF use a proven MEMS capacitive design with integrated electronics to provide a differential analog voltage output and a flexible supply range (5–40 VDC). The MF (Medium-Frequency) variant offers extended frequency response and a robust mechanical design with high shock resistance.

Performance

• Frequency response (±3 dB): DC to 7 kHz
• Shock resistance: up to 6,000 g

Housing
The device features a stainless-steel housing with protection class IP67, a flat form factor for easy mounting and an integrated cable with configurable length and connectors.

Applications
Typical applications include NVH (noise, vibration, harshness) measurements, test bench and vehicle dynamics testing, driving comfort evaluation and other industrial medium-frequency acceleration measurements.
