- Mount & Fully Guarded Target Universal Shaft Sensor



The Whirligig is a fully guarded target for easy mounting of motion sensors. It is a universal shaft sensor mount suitable for all industry standard cylindrical (18 and 30 mm) or DIN style inductive sensors including 4B's M100, M300, M800 Elite and Milli-Speed sensors. The sensor bolts to the Whirligig base plate and the complete assembly either bolts to the machines shaft through a 1/2 in. UNC tapped hole, or is connected magnetically using 4B’s patented Mag-Con™ adaptor. Shaft or machine vibration does not affect the performance of the sensor, as the whole assembly moves with the shaft. With the Whirligig, installation of speed sensors is now simple, safe and reliable.
