ASC 74C1 Triaxial acceleration sensor for crash and drop testing on lightweight structures

Ultra-compact, lightweight piezoresistive MEMS sensor with DC response and mV output – ideal for dynamic impact testing on small objects and structures.

Key features

True DC response from 0 Hz
Measurement ranges: ±500 g, ±1000 g, ±2000 g
Three independent axes (X, Y, Z) with Wheatstone bridge output
Shock resistant up to ±5000 g
Only 16 grams, ideal for small-scale setups

Performance highlights

The ASC 74C1 is a compact triaxial accelerometer sensor based on piezoresistive MEMS technology. It offers accurate DC measurement on all three axes using independent Wheatstone bridges that deliver a ratiometric mV output. Thanks to its static (DC) and dynamic measurement capabilities, the sensor is ideal for a wide range of crash tests, drop simulations, and structural motion analysis.

Each axis is protected against mechanical overload via internal stops, allowing the sensor to withstand shocks up to ±5000 g. Its cubic anodized aluminum housing and low mass (only 16 g) make it perfect for use in high-g-force environments with limited mounting space or strict weight constraints.

Usage conditions

The ASC 74C1 features an IP65-rated aluminum housing sealed with epoxy for extra protection in test environments. It operates between –20 °C and +80 °C and comes standard with a 6-meter PUR cable (Ø 3 mm). The sensor can be mounted using screws or adhesive, depending on application requirements.

Applications

Automotive crash test and sled impact simulations
Drop and shock testing of small or lightweight structures
Wearable system acceleration data capture
R&D labs and test centers
Biomechanics and dummy sensor integration

Advantages

The ASC 74C1 offers highly precise acceleration signals in three axes while maintaining extremely low weight and compact form. It combines DC response, high linearity, and excellent shock tolerance – making it ideal for any MEMS accelerometer application where both resolution and ruggedness matter. Engineers appreciate the simplicity of its signal output and its flexibility for both temporary and permanent test setups.
