Shaft Sensor Mount ¦ Whirligig

Supplier: 4B Australia

The Whirligig is a fully guarded target for easy mounting of motion sensors.

Price Guide: POA

The ‘Whirligig’ three in one target/bracket/guard is suitable for all industry standard cylindrical or DIN style inductive sensors including 4B's M100, M300 and M800 speed sensors. The speed sensor bolts to the Whirligig base plate, and the complete assembly bolts to the machine's shaft. The installation of speed sensors is now simple, reliable and fully guarded. Shaft or machine vibration does not affect the performance of the sensor, as the whole assembly moves with the shaft.


  • Universal application - Suits all DIN style and industry standard cylindrical sensors
  • Easy Installation – only requires an M12 tapped hole in the machine's shaft or use the MagCon for magnetic connection
  • Safe - Fully enclosed targets
  • Included brackets for 30mm and 18mm diameter sensors

4B also offers a heavy duty stainless steel version of the Whirligig.
