High-sensitivity accelerometer B11A51

uniaxialIEPEwith analog output

Product Overview
The B11A51 is a high-sensitivity uniaxial IEPE accelerometer designed for precise low-frequency and broadband vibration measurements in industrial and test environments. It delivers 5000 mV/g sensitivity, a ±1.0 g range and a 0.1–400 Hz (5%) frequency response. The sensor features a stainless steel housing with laser-welded IP68 sealing, a top MIL-C-5015 connector and a 1/4-28 female mounting.

Applications

• Vibration monitoring and condition-based maintenance
• Modal analysis and structural testing
• Environmental and climatic test chambers
• Aerospace, transport and industrial test rigs

Features

• Fast lead time
• High sensitivity (5000 mV/g) for low-amplitude measurements
• IEPE output for direct connection to standard data acquisition systems
• Laser welded IP68 sealing for use in harsh environments
• Stainless steel housing and robust mechanical mounting (1/4-28 female)
