High-sensitivity accelerometer B12A51

uniaxialIEPEIP68

Product overview
The B12A51 is a high-sensitivity IEPE uniaxial accelerometer designed for seismic and low-frequency vibration measurements. It features a stainless steel housing with laser-welded IP68 sealing and a MIL-C-5015 top connector. Typical applications include seismic monitoring, structural testing and other precision vibration measurements.

Features

• Uniaxial IEPE output optimized for low-frequency/seismic use
• Very high sensitivity: 10000 mV/g
• Low broadband resolution for precise measurements
• Laser-welded IP68 sealing for harsh environments
• Stainless steel housing and 1/4-28 female mounting

Additional

• Fast lead time
