Model 787-500-M12 Low-Frequency Accelerometer

Brand: Wilcoxon Sensing Technologies
Request Information
Wilcoxon’s side-exit 787-500-M12 high-sensitivity broadband sensor is supplied with the popular 4 pin M12 connector. The accelerometer offers an interior sensing element capable of producing 500 mV/g. The low-end frequency cutoff of the amplifier is designed to offer clear signals down to 0.2 Hz. 

The low-end frequency response makes it ideal for slow-speed applications such as wind turbine generators and cooling towers. Broadband frequency response to 10,000 Hz means the sensor is capable of detecting signals of early bearing fault, gearbox wear, and other high-speed applications such as spindles.
Features
  • Low-Profile
  • Rugged design
  • High sensitivity
  • Hermetically sealed
  • ESD protected
  • Reverse wiring protection
  • Clear signals at low vibration levels
  • Extended low-end frequency response
  • Improved signal-to- noise ratio versus other general-purpose accelerometers
  • Comes with industry popular M12 connector
  • Manufactured in an approved ISO 9001 facility
