Overview
The B05Y39 is a general-purpose three-axis IEPE accelerometer built on a piezoelectric ceramic shear structure with a wide-bandwidth frequency response and a highly integrated miniature built-in circuit. With 50 mV/g sensitivity and a ±100 g range it is a high-sensitivity model in the family for low-level triaxial vibration where signal-to-noise matters more than g range. Typical uses include body and cabin NVH, modal and structural analysis, condition monitoring and low-amplitude environmental testing.
High-quality ceramics ensure long-term stability and the built-in low-impedance circuit keeps noise low. The laser-welded titanium-alloy 12.2 mm cube weighs just 6.3 g, with a glass-sealed 8-36 4-pin connector carrying all three channels on one cable and a calibration hole on every axis. It mounts by M2.5 × 2.0 stud or adhesive, and insulating mounting hardware ships as standard.
Why engineers choose the B05Y39
Three axes, one mounting point
Simultaneous X, Y and Z measurement from a single 12.2 mm cube with ≤ 5% transverse sensitivity. Per-axis calibration holes make coupling checks and calibration straightforward, and the isolated mounting plate keeps ground loops out of multi-channel setups.
Built-in IEPE electronics
Highly integrated miniature low-impedance circuit with 2–20 mA constant-current excitation and 8–12 V bias. Spectral noise of 8 µg/√Hz at 100 Hz and 0.0002 g rms broadband resolution drive long cables into any IEPE-compatible DAQ.
Lightweight titanium cube
Laser-welded titanium-alloy cube sealed to IP68 with a glass-sealed connector, weighing 6.3 g and rated to 800 g rms vibration and 2,000 g pk shock, with bandwidth to 7 kHz and resonance ≥ 39 kHz. Stud or adhesive mounting.
Typical applications
HALT/HASS and environmental stress screening
Automotive NVH testing
Modal and structural analysis
General vibration monitoring
Small components and light structures sensitive to mass loading
