Performance highlights

The ASC 4321MF is a uniaxial accelerometer based on advanced MEMS capacitive technology, designed for medium-frequency applications. With a measurement range up to ±200 g and a frequency response up to 7 kHz (±3 dB), the sensor is ideal for NVH measurements, ride comfort testing, and dynamic analysis in the automotive sector.
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.

Operating conditions

This lightweight sensor (just 7 grams) features an anodized aluminum housing and IP65 protection against dust and splashing water. It offers high shock resistance up to 6,000 g and operates in a wide temperature range from -40 °C to +125 °C, making it suitable for harsh testing environments.

Applications

• NVH analysis (Noise, Vibration, Harshness)
• Ride comfort and vehicle stability testing
• Automotive R&D and component validation
• Test bench use and driving dynamics analysis

Advantages

The ASC 4321MF offers an excellent balance between weight, accuracy, and durability. Its flat design and easy mounting make it ideal for installations in confined spaces such as underneath vehicles or on test benches. The low noise output and high reliability ensure precise and repeatable measurement results in demanding setups. 

Other Features

• Available with TEDS module
• Supplied with factory calibration (ISO 17025 optional)
• Custom cable and connector configurations
• Mountable via adhesive or screw holes
