Magnetic rotary encoders – bearingless speed measurement
The bearingless magnetic rotary encoders MAG incremental are particularly well suited for mounting situations with very limited space, without a free shaft end or with large shaft diameters of up to approx. 1,350 mm.
Magnetic rotary encoders are insensitive to dust, soiling, external magnetic fields, liquids and condensation (operation in media possible). Additionally, they are wear-free.
Reliable
The MAG incremental magnetic rotary encoders are extremely resistant to external influences such as shock, vibration, dust or liquids and ensure optimal system availability.
- Long lifetime – bearingless and contactless, no mechanical wear
- Robust, fully encapsulated electronics in a special heavy-duty housing
- Robust mechanics capable with heavy duty fixing equipment
- High-precision signal through special multiple scanning
- Optional: pulse wheel cover for additional protection of the magnetic tracks
Flexible
The MAG incremental magnetic rotary encoders are suitable for a large number of applications and mounting situations.
- For shaft diameters up to 1,350 mm
- For mounting situations with or without a free shaft end
- Split pulse wheel – ideal for retrofit projects
- Suitable for high speed
- Extra-wide systems for large axial shaft excentricity
- Extra-narrow systems for extremely restricted installation spaces
- Flexible number of scanning heads for multiple output signals
- Optional: speed switch, fiber optic transmitter
Tailor-made and safe
The MAG incremental magnetic rotary encoders are designed, adapted and manufactured for the respective application.
- Modular concept enables customized solutions
- Engineering support: recording of the installation situation, preparation of sketches and proposing of solutions, order-related design and calculation, manufacturing and delivery including all accessories, assembly, after-sales service
- Centrifugal force and fatigue resistance calculations for each application
