Hübner Berlin, now Baumer Hübner, is the Baumer competence center for HeavyDuty sensors for drive technology.
The brand Hübner Berlin represents the global standards for reliable encoders, tacho generators and speed switchtes in proven HeavyDuty technology.
More than 60 years of expertise and experience as global market leader merge with cutting-edge technologies in unmatched robust and durable products.
Proven HeavyDuty principle
The extremely resilient housings are key for the unrivalled service life and reliability of the Baumer HeavyDuty encoders.
These robust housings with solid and thick walls are the perfect protection against outside impacts.
The torsion-resistant design is intended to endure high loads by shock and vibration.
Durable double-sided bearing setup
Thanks to unmatched resistance to axial and radial load, the Baumer concept of bearings at both shaft ends is well proven and tried and tested for decades in electrical machinery engineering.
Baumer HeavyDuty encoders feature - wherever mechanically feasible - bearings at both encoder shaft ends for unrivalled long service life and maximum mechanical reserve capacity.
Outstanding, sea water resistant corrosion protection
Baumer HeavyDuty rotary encoders are ideally suited for corrosive environments thanks to optimized material selection and highly resistant coatings for successful long-term use, for example near shore and offshore.
Their corrosion protection corresponds to categories C4 or CX (C5-M) in accordance with the standard EN ISO 12944.
Special equipment options for operation in the arctic, tropics and desert are available on request.
Long-term stable sealing concept
The elaborate Baumer HeavyDuty sealing concept allows the protection class IP 66 and IP 67 over a wide temperature range up to +95 °C.
Thanks to a sophisticated combination of labyrinth and shaft seals, the HeavyDuty encoders are permanently protected against all types of solid, moist and pasty contamination.
Reliable protection against shaft currents
Particularly in the case of rotary encoders on frequency converter-controlled electric motors, current overshoots in the ball bearing of the rotary encoder may occur.
The lubricant can burn locally and the lubricant effect can be impaired.
Electrically insulated bearings provide a remedy for this failure.
Some hollow shaft designs come with isolated or hybrid ball bearings to compensate shaft currents.
Additional slip ring earthing (optional) can be used for capacitive shaft current discharge.
Solid shaft encoder designs provide spring washer couplings with isolated hub as protection against shaft currents.

Best electromagnetic compatibility
Baumer encoders with proven HeavyDuty technology by Hübner Berlin come in interference-resistant design which has been optimized according to latest EMC knowledge.
All products are tested upon burst reistance, at high-voltage up to 4 kV.
High-power signal output drivers
The incremental square signal outputs provide high-performance and short-circuit proof output drivers to endure current peaks up to 300 mA.
They ensure reliable signal quality even in long-distance transmission, i.e. HTL-P up to 350 m and TTL up to 550 m.
EURO flange B10
The EURO flange B10 is the global mounting standard for HeavyDuty shaft encoders.
Baumer offers a unique portfolio of encoders and tacho generators with EURO flange B10.
Integrated function monitoring
The integrated function monitoring EMS (Enhanced Monitoring System, Option) continuously checks numerous rotary encoder functions.
The convenient diagnostics enables higher availability, because connection and encoder errors are detected more quickly.
The encoder status can be continuously transmitted to the controller via an error output.
Leading edge SinCos signal quality
LowHarmonics is the world's leading technology for producing sinusoidal signals with a negligibly small harmonic content.
LowHarmonics sine wave encoders provide better control, lower drive heating and higher energy efficiency.
Mechanical and electronic speed switches
Mechanical and electronic speed switches often fulfill the decisive safety function when overshooting or subtracting rotary speeds, in addition to the rotary encoder.
In applications with functional safety, our speed switches are classified as standard components as defined in the Machinery Directive 2006/42 / EC.
The assessment and certification of the complete system with speed switches according to e.g. EN ISO 134849 is mandatory to be carried out by a notified body.
LongLife tachos with the silver track
HeavyDuty tachogenerators in LongLife technology are based on a silver track embedded in the commutator.
LongLife tachogenerators combine the best signal quality for high control dynamics, maximum robustness and unrivaled long service life.
The LongLife technology also supports to detect low speeds precisely in real time.
Large variety of HeavyDuty combinations
In HeavyDuty product combinations, HeavyDuty encoders, tacho generators and speed switches build one single and robust unit.
This way, besides the speed information other signals are available for control evaluation for multiple application tasks in drive technology.
HeavyDuty product combinations deliver various output signals using one single shaft. They offer significant space-saving capabilities and ensure maximum durability and service life.
Robust, precise absolute singleturn sensing
The robust and precise absolute singleturn sensing unit delivers precise (incremental) signals even at high temperatures and under adverse conditions to ensure high control quality.
For maximum efficiency and process control in the application.
Ultra-robust high-precision absolute magnetic singleturn sensing
The magnetic singleturn sensing unit delivers precise (incremental) signals even at high temperatures and under adverse conditions to ensure high control quality.
The precision is comparable with optical sensing technology.
For maximum efficiency and process control in the application.
Energy harvesting HeavyDuty revolution counter
The unique, patented HeavyDuty microgenerator MicroGen gains its energy directly from the movement of the rotary shaft.
It also operates extremely reliably without a battery or without a gearbox, even in the long-term use.
It has no wear-bearing parts and does not require any maintenance.
The Energy Harvesting revolution counter has proven itself over the past 10 years in the toughestHeavyDuty application and is the heart of the absolute Baumer HeavyDuty rotary encoders.
Functional safety with certified safety components
SIL / PL certified sensors, encoders and signal evaluation units used as safety components in the sense of the machine directive 2006/42/EG simplify system safety evaluation and functional safety implementation in the application.
Safety evaluation and safety certification of a complete system according to e.g. EN ISO 134849 is mandatory to be carried out by a notified body.
Intelligent HeavyDuty encoders
The intelligent encoders deliver position and signal information for speed control in harsh environments.
What’s new: configuration and monitoring.
A wireless LAN programming adapter allows customized settings and on-site optimization of device parameters.

Thanks to an integrated web server, access is possible via standard web browser without software installation.
The monitoring function clearly visualizes actual encoder signals, for example during commissioning.
The simple parameter download simplifies the documentation. Password protection prevents unwanted manipulations.
Offline mode
For use cases pre-parameterization, function diagnostics and commissioning of an encoder.
The encoder does not have to be installed in a machine or plant.
