B05BM1

The B05BM1 is a miniature teardrop 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 circuit gives excellent long-term output stability and repeatability, and the laser-welded titanium-alloy teardrop housing keeps the whole sensor to 15.7 × 8.5 × 5.1 mm and 1.5 g for minimal mass loading on the test structure. The low-profile M3 side connector and adhesive base mount make it easy to install where space is tight.

Minimal mass loading

At 1.5 g and 15.7 × 8.5 × 5.1 mm, the B05BM1 barely changes the response of PCBs, small components and light structures, so what you measure is the structure, not the sensor.

Miniature built-in 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 teardrop

Laser-welded titanium-alloy teardrop housing sealed to IP68, rated to 800 g rms vibration and 2,000 g pk shock, with bandwidth to 10 kHz and resonance ≥ 38 kHz. Adhesive mount with an M3 side connector.
