B02A14

The B02A14 is a micro uniaxial IEPE accelerometer built on a piezoelectric ceramic shear structure with a wide-band frequency response and an integrated microminiature circuit. With 10 mV/g sensitivity, a ±500 g range and a ±5% response from 1 Hz to 10 kHz, it packs general-purpose performance into a 4.7 g titanium housing with a top M5 connector, for modal analysis, vibration control and general vibration monitoring on small or light structures where a full-size sensor would load the test article.

High-quality piezoelectric ceramics ensure long-term stability for years of precise measurement, memory-alloy fasteners keep the shear structure stable and reliable, and the internal low-impedance circuit delivers low noise (40 µg/√Hz at 100 Hz) with a favorable temperature response. The laser-welded titanium-alloy HEX 11 × 20.7 mm housing is sealed to IP68 and rated to 3,000 g rms vibration and 8,000 g pk shock, with an M5 stud thread on the base and 10-32 connector and thread versions available.

Micro size, full performance

At 4.7 g and HEX 11 × 20.7 mm, the B02A14 adds almost no mass to PCBs, small components and light structures, yet keeps the 10 mV/g sensitivity, ±500 g range and 1 Hz to 10 kHz bandwidth of a general-purpose sensor.

Built-in IEPE electronics

Integrated microminiature low-impedance circuit with 2–20 mA constant-current excitation and 8–12 V bias. Spectral noise of 150 / 40 / 20 µg/√Hz at 10 / 100 / 1000 Hz and 0.001 g rms broadband resolution drive long cables into any IEPE-compatible DAQ.

Rugged titanium housing

Laser-welded titanium-alloy housing with memory-alloy fasteners, sealed to IP68 and rated to 3,000 g rms vibration and 8,000 g pk shock, with resonance ≥ 65 kHz. Top connector with M5 or 10-32 options and an M5 stud mount.
