Model 786-500-M12 General-Purpose Low-Frequency Accelerometer

Brand: Wilcoxon Sensing Technologies
Wilcoxon’s top-exit 786-500-M12 sensor offers clear signals at low vibration levels. The sensor is designed with extended low-end frequency response and improved signal-to-noise ratio compared to other general-purpose models. 

It can be used to detect both low- and highspeed vibrations and is optimized for detecting vibration on slow turning machinery such as cooling tower fans and slow-speed gearboxes. The sensor comes with the popular M12 connector.
Features
  • Rugged design
  • Comes with industry popular M12 connector
  • High sensitivity
  • Hermetically sealed
  • ESD protected
  • Reverse wiring protection
