Overview
The B03CM1 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 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 circuit gives excellent long-term output stability and repeatability, and the laser-welded titanium-alloy teardrop housing keeps the whole sensor to 11 × 8.5 × 5.1 mm and 1 g for minimal mass loading on the test structure. An integral high-temperature cable with a side exit and the adhesive base mount make it easy to install where there is no room for a connector.
Why engineers choose the B03CM1
Minimal mass loading
At 1 g and 11 × 8.5 × 5.1 mm, the B03CM1 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 20 µg/√Hz at 100 Hz, 0.0005 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 1,200 g rms vibration and 3,000 g pk shock, with bandwidth to 10 kHz and resonance ≥ 38 kHz. Adhesive mount with an integral side-exit cable.
Typical applications
PCB and electronics vibration testing
Environmental stress screening (ESS)
Vibration measurements in confined spaces
Small-component and product qualification
Lightweight structures sensitive to mass loading
