C02BM6

The C02BM6 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 10 pC/g charge sensitivity and a ±1,000 g range it is the most sensitive member of the family, with 10 pC/g and a ±1,000 g range in a low-profile side-connector housing. Typical uses include small-scale modal testing, PCB and electronics testing, ESS and low-clearance installations where a side cable exit helps.

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 14.4 × 8.5 × 6.6 mm and weighs 2.6 g, so it adds almost no mass to small or light test articles. It mounts with adhesive and carries a side M5 connector, with a 10-32 connector version available.

Minimal mass loading

At 2.6 g and 14.4 × 8.5 × 6.6 mm, the C02BM6 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 C02BM6 runs continuously at +160 °C and pairs with any charge amplifier or charge-input DAQ, with 650 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 1 Hz to 6 kHz (±10% over 0.5 – 10k Hz) with resonance ≥ 33 kHz, 1% non-linearity and ≤ 5% transverse sensitivity, rated to 3,000 g rms vibration and 4,000 g pk shock.
