4B Heavy-Duty Whirligig® – Shaft Sensor Mount
The Heavy-Duty (HD) Whirligig® is a fully guarded target for easy mounting of motion sensors, built for the toughest rotating machinery. It works with 4B's inductive proximity sensors including the M100 Stopswitch, P100 ProxSwitch, and P300 ProxSwitch.
Used on conveyors, bucket elevators, and other rotating equipment, the HD Whirligig monitors shaft speed for continuous, low-speed, or high-speed conditions. The sensor (sold separately) inserts into the HD Whirligig housing and the complete assembly bolts to the machine shaft through a UNC tapped hole. Because the assembly turns with the shaft, machine vibration or movement does not affect performance.
