High-sensitivity accelerometer B12A03

uniaxialIEPEwith built-in electronics

Product overview
Compact high-sensitivity uniaxial IEPE accelerometer for low-amplitude vibration measurement. Sensitivity 10000 mV/g and measurement range ±0.5 g make it suitable for precision modal analysis and structural testing. Stainless steel housing with laser welding provides IP68 protection. Top connector and 10-32 female mount enable straightforward installation.
