Heidenhain angle encoders- Versions: RON RON ROD ROD RCN

 

 

Sealed Angle Encoders
Angle Encoders with Integral Bearing, Hollow Shaft and Integral Stator Coupling: RON and RCN

The stator coupling is configured so that during angular acceleration it absorbs only the torque resulting from bearing friction. The HEIDENHAIN angle encoders RON and RCN are therefore characterized by excellent dynamic performance. Since the stator coupling is integrated, the specified system accuracy includes the error of the shaft coupling.

Further advantages:
 Short overall length and small space requirement
 Hollow shafts with diameters up to 60 mm for supply lines, etc.
 Simple mounting



Angle Encoders with Integral Bearing and Solid Shaft: ROD

Angle encoders with stub shafts are particularly well suited for applications with high rotational speeds or where large mounting tolerances are required. Precision couplings permit axial tolerances up to 1 mm for shaft coupling.

    Because of the design and mounting of the stator coupling, it must only absorb that torque caused by friction in the bearing during angular acceleration of the shaft.

     Advantages:

    • Compact size for limited installation space
    • Hollow shaft diameters up to 100 mm for leading power cables, etc.
    • C axes on lathes
    • Simple mounting

    ROD angle encoders with solid shaft are particularly suited to applications where higher shaft speeds and larger mounting tolerances are required. The shaft couplings allow axial tolerances of  1 mm.

    Angle encoders without integral bearing (modular angle encoders) are intended for integration in machine elements or apparatuses. They are suited for the following requirements:
    • Large hollow shaft diameter (up to 10 m with a scale tape)
    • High shaft speeds up to 40000 rpm
    • No additional starting torque from shaft seals
    • Segment solutions
