C01AM2

The C01AM2 is a charge-mode (PE) miniature accelerometer built on a piezoelectric ceramic shear structure with a wide-bandwidth frequency response and excellent long-term stability and repeatability. With 4 pC/g charge sensitivity and a ±2,000 g range it is the top-connector hex member of the family, with 4 pC/g and a ±2,000 g range in a 9 mm titanium housing. Typical uses include small-scale modal testing, PCB and electronics testing, ESS and vibration measurement in confined spaces where a top cable exit is easier.

With no built-in electronics the sensor works from −50 °C to +160 °C and pairs with any charge amplifier, which sets the low-frequency limit of the system. Shape-memory alloy fasteners keep the shear structure stable and reliable, and the laser-welded titanium-alloy housing measures just HEX 9 × 9.4 mm and weighs 2 g, so it adds almost no mass to small or light test articles. It mounts with adhesive and carries a top M5 connector, with a 10-32 connector version available.

Minimal mass loading

At 2 g and HEX 9 × 9.4 mm, the C01AM2 barely changes the response of PCBs, small components and light structures, so what you measure is the structure, not the sensor. Adhesive mounting for fast installation on any flat surface.

Charge mode, +160 °C

No internal electronics means nothing to overheat: the C01AM2 runs continuously at +160 °C and pairs with any charge amplifier or charge-input DAQ, with 90 pF capacitance and ≥ 10¹¹ Ω insulation resistance for a clean, stable charge signal.

Shear-mode piezoceramic

Shear structure with shape-memory alloy fasteners gives a ±5% response from 0.5 Hz to 5 kHz (±10% over 0.3 – 7k Hz) with resonance ≥ 27 kHz, 1% non-linearity and ≤ 5% transverse sensitivity, rated to 2,500 g rms vibration and 3,000 g pk shock.
