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.
