Overview

The B03BM6 is a miniature uniaxial IEPE accelerometer with a built-in miniature impedance converter that conditions the piezoelectric charge signal to a low-impedance voltage output. With 20 mV/g sensitivity and a ±250 g range it is a wide-bandwidth mid-range member of the family, balancing range and noise for general vibration work in confined spaces. Typical uses include PCB vibration testing, ESS, component qualification and vibration measurements in confined spaces.

A highly integrated miniature ASIC gives excellent long-term output stability and repeatability, and the laser-welded titanium-alloy housing keeps the whole sensor to 13.6 × 6.6 × 7.7 mm and 2 g for minimal mass loading on the test structure. The adhesive base mount and low-profile side connector make it easy to install where space is tight.

Why engineers choose the B03BM6

Minimal mass loading

At 2 g and 13.6 × 6.6 × 7.7 mm, the B03BM6 barely changes the response of PCBs, small components and light structures, so what you measure is the structure, not the sensor.

Miniature ASIC electronics

Built-in impedance converter with 2–20 mA constant-current excitation delivers a low-impedance IEPE output with spectral noise of 20 µg/√Hz at 100 Hz, 0.0005 g rms broadband resolution and excellent long-term stability and repeatability.

Laser-welded titanium housing

Laser-welded titanium-alloy housing sealed to IP68, rated to 1,200 g rms vibration and 3,000 g pk shock, with bandwidth to 10 kHz and resonance ≥ 38 kHz. Adhesive mount with side connector, M5 or 10-32.

Typical applications

PCB and electronics vibration testing
Environmental stress screening (ESS)
Low-clearance installations where a side cable exit helps
Small-component and product qualification
Lightweight structures sensitive to mass loading
General-purpose uniaxial vibration measurement
