Description : MDR20-P44B magnetic drum is made of bonded multi-pole magnet; it is used in a wide variety of speed and commutation applications such as to rotary encoders, speedometers and machine controls. Three standard grades of magnetic materials are offered to fulfill a broad spectrum of magnetic field requirements along with a high resistance to demagnetization. Combined with a Nylon polymer binder, they offer excellent dimensional control and tough environmental endurance. Multi-pole rotors can be modified to have other pole patterns, custom compounded binders, or metal inserts for specialized applications.

Features :

Rugged, chip free construction
Wide range of pole counts
Three grades of magnetic materials
High resistance to demagnetization
Operation from -40 to 125 degrees C
Well suited for general industrial environments
Aluminum hub with set screw
