Overview

The B05BM6 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 50 mV/g sensitivity and a ±100 g range it is a high-sensitivity model in the family for low-level vibration on light structures where mass loading and signal-to-noise both matter. Typical uses include PCB and electronics testing, modal surveys on light structures, ESS and low-amplitude 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 2.1 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 B05BM6

Minimal mass loading

At 2.1 g and 13.6 × 6.6 × 7.7 mm, the B05BM6 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 8 µg/√Hz at 100 Hz, 0.0002 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 800 g rms vibration and 2,000 g pk shock, with bandwidth to 12 kHz and resonance ≥ 40 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
