A01D06

The A01D06 is a shock-resistant uniaxial capacitive MEMS accelerometer with true DC response, so it measures static acceleration, tilt and slow motion as well as vibration and survives 10,000 g shocks that would destroy a standard DC accelerometer. A variable-capacitance MEMS element with internal AC excitation and demodulation outputs a single-ended voltage signal proportional to acceleration, and with 4 mV/g sensitivity and a ±500 g range it is the highest-range model in the family, with ±500 g, 5 kHz bandwidth and a 41 kHz resonance for crash pulses and severe overload events measured down to DC. Typical uses include crash and impact pulse measurement, overload and drop testing, road-load acquisition at the wheel and suspension and high-level low-frequency events.

The response is flat within ±5% from DC to 5 kHz (±10% to 8 kHz) with a 41 kHz resonance, ≤ 1.5% transverse sensitivity and 0.25% typical non-linearity, a ±2 V full-scale output and noise of 125 µg/√Hz over 0 – 100 Hz. It runs from any 6 – 30 VDC supply with low power consumption. The laser-welded titanium-alloy HEX 16 × 15 mm housing weighs 10.2 g, is sealed to IP68, and carries a 1/4-28 4-pin connector with the signal ground isolated from the housing and an M5 stud mount (10-32 optional).

Survives 10,000 g

Rated to 10,000 g pk shock and 10,000 g rms vibration, so the sensor keeps working through crash pulses, drops and hard impacts that exceed the survival limit of most DC-response accelerometers, and the 41 kHz resonance keeps the response clean to 5 kHz.

True DC response

Capacitive MEMS sensing measures from 0 Hz, so static tilt, sustained acceleration and slow motion are captured alongside vibration to 5 kHz. Transverse sensitivity ≤ 1.5%, non-linearity 0.25% typical, with a single-ended ±2 V full-scale output from a 6 – 30 VDC supply at low power.

Rugged sealed titanium

Laser-welded HEX 16 × 15 mm titanium-alloy housing sealed to IP68, weighing 10.2 g and rated to −40 to +125 °C. Signal ground isolated from the housing, 1/4-28 4-pin connector and M5 stud mount at 3.0 N·m, with a 10-32 thread version available.
