Intégration facile grâce à des designs compacts

Compact machine design
- OnAxis encoders operate on axial sensing, which makes them ideal for applications where space around the shaft is limited
Reliable long-term operation even under extreme conditions
- Robust magnetic sensing fully free from wear
- Resistant to dirt, vibration and shock
- Immune to bearing loads
Immune to shaft currents
- Particularly in rotary encoders installed at powerful electric drives, ball bearings may be damaged by shaft currents
- The sensor head being decoupled from shaft will solve the problem
Long-term high IP protection
- The bearingless design allows for high and yet cost-efficient IP protection
- Even at high speed the encoder is protected against water and dust ingress
- Improved robustness by electronics being decoupled from moving parts
Designed for mobile automation
- High EMC robustness thanks to E1-compliant design
- Wire cross-section of 0.5 mm² for optional pre-assembly of automotive connectors (DEUTSCH, etc.)

Technological highlights

Magnetic sensing requires no bearings between sensor head and material measure (here a center magnet). This way they can be positioned separated from each other. This allows for rather high mounting tolerances and increased flexibility in design and mounting. As there is no need for bearings, there is no conventional wear and tear either. This way the encoders are immune to dust, dirt, textile fibers, shaft currents or bearing loads and robust against vibration and shock.

Immune instead of robust

Thanks to magnetic sensing, bearingless encoders are immune to wear and disturbances caused by dust, dirt or fibers
The encoders achieve particularly high protection classes even at high speeds, as they do not require a complex impermeability concept without bearings
In addition, the encoders can be integrated into the machine design so that they are better protected against mechanical impacts
High speeds and long service life are easily compatible, as self-heating and wear of ball bearings are eliminated

Functionality of axial sensing

Axial sensing requires a sensor head and a center magnet
The center magnet is attached centrally to the shaft end
The magnet consists of a pair of poles and provides an absolute signal with each rotation
An internal signal processing generates up to 16384 steps from the SinCos period

Mounting with axial scanning

When mounting the magnet, make sure that the magnetization direction of the permanent magnet (north-south pole) is aligned parallel to the active surface of the sensor
The permanent magnet should not be installed in ferromagnetic materials such as steel, as otherwise the working distance may be negatively affected

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
