Overview

The B05Y32 is a miniature three-axis IEPE accelerometer built on a piezoelectric ceramic shear sensing element with a wide-bandwidth response to 10 kHz. With 50 mV/g sensitivity and a ±100 g range it is a high-sensitivity model in the BXXY32 miniature family for low-level vibration where signal-to-noise matters more than g range. Typical uses include structural and modal testing, vehicle body and cabin NVH, machinery vibration monitoring and low-amplitude R&D measurements.

A highly integrated miniature ASIC provides a low-impedance output with low noise and stable sensitivity over temperature, and high-grade ceramics deliver long-term output stability. The 11 mm cube titanium-alloy housing is laser welded to IP68, each axis has an M2.5 mounting thread, and insulated mounting hardware is included as standard.

Why engineers choose the B05Y32

Small form factor

An 11 mm cube package weighing just 5.5 g fits space-constrained installations and adds minimal mass loading, while the shear sensing element keeps the output stable and reliable.

Miniature ASIC electronics

Highly integrated IEPE circuit with 2–20 mA constant-current excitation. Spectral noise of 8 µg/√Hz at 100 Hz, 0.0002 g rms broadband resolution and excellent high-frequency response.

Rugged titanium cube

Laser-welded titanium housing sealed to IP68, rated to 800 g rms vibration and 2,000 g pk shock. M2.5 thread on every axis and an isolated mounting plate as standard.

Typical applications

  • Automotive and aerospace NVH measurements
  • Modal analysis
  • HASS / HALT testing
  • Vibration monitoring
  • Space-constrained and lightweight test articles
  • General-purpose triaxial vibration measurement
