Overview
The B03Y41 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 20 mV/g sensitivity and a ±250 g range it is a versatile mid-range member of the family, balancing range, bandwidth and noise for general triaxial vibration work. Typical uses include automotive NVH, environmental testing, modal analysis and general vibration monitoring.
High-quality ceramics ensure long-term stability and the built-in low-impedance circuit keeps noise low. The 15 × 15 × 10 mm laser-welded titanium-alloy housing weighs just 8 g, and a ⌀4.1 mm center through-hole lets the sensor be bolted down at any orientation while each axis keeps its own M2.5 hole for coupling and calibration. Insulating mounting hardware ships as standard and a single 1/4-28 4-pin connector carries all three channels.
Why engineers choose the B03Y41
Three axes, one bolt
Simultaneous X, Y and Z measurement from a single 15 × 15 × 10 mm block with ≤ 5% transverse sensitivity. The center through-hole mounts 360° at any angle, and per-axis M2.5 holes make coupling checks and calibration straightforward.
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 20 µg/√Hz at 100 Hz and 0.0005 g rms broadband resolution drive long cables into any IEPE-compatible DAQ.
Lightweight titanium block
Laser-welded titanium-alloy housing sealed to IP68, weighing 8 g and rated to 1,200 g rms vibration and 3,000 g pk shock, with bandwidth to 9 kHz and resonance ≥ 60 kHz. Insulated mounting hardware included.
Typical applications
HALT/HASS and environmental stress screening
Automotive NVH testing
General vibration monitoring
Modal and structural analysis
Durability and shaker testing
General triaxial vibration measurement
