磁感應技術允許感應單元和磁體（通常是磁環）之間存在較大的間隙。因此，二者可以分開安裝，而不必像傳統旋轉編碼器一樣需要借助精密滾珠軸承才能完成安裝。同時，這種設計允許較大的安裝誤差，從而提高設計和安裝靈活性。此外，沒有軸承，也就沒有常見的磨損現象。因此，無軸承編碼器能有效抵御灰塵、污垢或紡織纖維。此外，編碼器還不受軸電流或軸承載荷的影響，具有出色的抗振動和抗沖擊能力。

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
