Overview

The B02Y31 is a compact three-axis IEPE accelerometer built on a piezoelectric ceramic shear structure. With 10 mV/g sensitivity and a ±500 g range it is the mid-range model in the BXXY31 family, giving an excellent balance between range and sensitivity for general vibration and moderate shock testing. Typical uses include automotive NVH, modal analysis, electronics validation and everyday R&D vibration work.

Built-in low-impedance IEPE electronics deliver low noise and a wide-bandwidth response, and high-quality ceramics ensure long-term stability. The 11 mm cube titanium-alloy housing is laser welded to IP68, each axis has its own M2.5 mounting hole for improved coupling and calibration, and insulating mounting hardware is included as standard.

Why engineers choose the B02Y31

Shear-mode piezoceramic

High-quality piezoelectric ceramic in a shear structure gives a wide-band response with 1% non-linearity and long-term stability for years of accurate measurement.

Built-in IEPE electronics

Integrated low-impedance circuit with 2–20 mA constant-current excitation. Spectral noise of 40 µg/√Hz at 100 Hz and 0.001 g rms broadband resolution.

Rugged titanium cube

Laser-welded titanium housing sealed to IP68, rated to 2,000 g rms vibration and 5,000 g pk shock. M2.5 mounting holes on every axis and an isolated mounting plate as standard.

Typical applications

  • Automotive NVH testing
  • Modal and structural vibration analysis
  • HASS / HALT and reliability screening
  • Electronic component and PCB validation
  • General vibration monitoring
  • General-purpose triaxial vibration measurement
