磁感应技术允许感应单元和磁体（通常是磁环）之间存在较大的间隙。因此，二者可以分开安装，而不必像传统旋转编码器一样需要借助精密滚珠轴承才能完成安装。同时，这种设计允许较大的安装误差，从而提高设计和安装灵活性。此外，没有轴承，也就没有常见的磨损现象。因此，无轴承编码器能有效抵御灰尘、污垢或纺织纤维。此外，编码器还不受轴电流或轴承载荷的影响，具有出色的抗振动和抗冲击能力。

Functionality of radial sensing

Magnetic ring encoders consist of a sensor and a measuring body (magnetig rotor or gear wheel).
The magnetic ring has several north and south poles
The number of poles depends strongly on the diameter of the magnetic rotor
Magnetic rotors at Baumer are available for shaft diameters from 6 to 3183 mm
Thanks to this mode of operation, the magnetic rotor can be integrated no matter how large the shaft is

High signal quality due to high-precision magnetization

The magnetic rotor is decisive for the signal quality
Baumer uses specially developed processes and equipment for the magnetization of the magnetic rings and thus achieves a very high signal quality
The magnetic rings can cover different requirements regarding material (elastomers or hard ferrite), measurement (incremental, incremental with zero pulse or absolute), pole pitch (2 or 5 mm) or other customer-specific magnetizations

Pole pitch determines resolution and installation tolerance

Rule of thumb: higher resolution = 2 mm pole pitch; higher installation tolerance = 5 mm pole pitch
The 2 mm pole pitch is standard for bearingless industrial encoders: Allows a higher resolution than a 5 mm pole pitch with the same magnetic ring diameter
The 5 mm pole pitch is standard for bearingless HeavyDuty encoders: It is suitable for large radial installation tolerances of up to 3 mm
Example: A magnetic ring with a diameter of approx. 40 mm has either 64 poles which are 2 mm wide or 26 poles which are 5 mm wide.
The resolution is therefore 2.5 times higher with a 2 mm pitch
Various pole pitches can be realized on request

Permanently high IP protection class

Bearingless encoders easily achieve a high IP protection class, especially at high speeds
Without bearings, they do not require a complex sealing concept
The entire measuring system has no wearing parts, making the encoders extremely durable
In addition, magnetic sensing is very robust against shock, vibration, dirt, dust and textile fibers
Seawater-resistant options are available with HeavyDuty encoders

Immune against shaft currents

Particularly in the case of rotary encoders on frequency inverter-controlled electric motors, current flashovers may occur in the ball bearing of the rotary encoder
The lubricant can burn locally and the lubricant effect can be impaired as a result
Thedecoupling of the sensor head from the shaft solves this problem
Without bearings, bearing damage due to shaft currents cannot occur
Baumer encoders with proven original HeavyDuty technology from Hübner Berlin have an optimized, interference-free design according to the highest EMC standards
All devices are tested for burst resistance, with high voltage pulses of up to 4 kV
