Bearings on both shaft ends for maximum service life
For more than 100 years one bearing at each shaft end has been a proven construction principle in electrical machinery. The interplay of two-sided bearings, robust Baumer mechanics and large ball bearings at optimum distance to compensate situation-induced shaft loads presents a performance class of its own. Baumer HeavyDuty encoders are experienced as being unparalleled durable and long-life - this combination is basis and guarantee why. In practice, this means: Ultimate reserve capacity and improved system availability by reduced maintenance effort. Even in harshest conditions. A true Baumer HeavyDuty encoder.
ShaftLock - for outstanding durability
The metal wall between the two ball bearings protects the bearings against axial shocks and load. This is the patented ShaftLock concept developed by Baumer. High-end materials and high-precision mechanics ensure optimum runout properties throughout the entire lifetime.
MicroGen multiturn sensing for absolute HeavyDuty encoders
- Energy Harvesting in PMG10 by patented multiturn technology MicroGen of latest generation
- Energy self-sufficient thanks to integrated micro generator
- Wear free, no gearings
- Environment-friendly and maintenance free without battery
HDmag - bearingless encoders by Baumer
Magnetic sensing is insensitive to dust and condensation which is a prerequisite for dependable operation in the heavy duty industry. In addition, non-contact technology allows for large tolerances on axial and radial backlash. This will ensure excellent signal quality even at strong shocks and vibration. State-of-the-art processing makes the most of the supplied high-quality precision signals to generate high resolutions for versatile use. The HDmag family with fully encapsulated electronics is compliant to IP67 rating and hence provides reliable protection against the ingress of dust, dirt and liquids throughout the entire service life. The troubleshooter for narrow installation space.
Excellent signal quality
The high-performance and robust power output drivers integrated in all incremental HeavyDuty encoders ensure excellent signal quality for reliable evaluation even in transmissions with up to 550 m (TTL) respectively 350m (HTL-P) cable length. The diagram is an example of the HOG 86 HTL signal amplitude (HTL) after 300 m at 100 °C and with 100 kHz output frequency. The competitive product supplies only half the signal amplitude at inferior signal quality which may lead to evaluation problems.
Easy and dependable speed monitoring
Mechanical speed switch
- Field-proven and energy-autonomous
- Operates on the mechanical centrifugal principle
- User-specific switching speed set as default
Digital speed switch
- User-programmable switching speed
- Integrated self-monitoring
- Up to three programmable switching speeds
- Integrated relay as an option
Motor earthing units
The durable Baumer motor earthing units dependably discharge parasitic currents and this way protect the bearings against shaft currents for maximum service life, while reducing repair cost and downtime in parallel. The price is only a fraction of the costs for a bearing exchange. Series ME12 comprises motor earthing units for shaft diameters from 20 to 42 mm.
The Original from Berlin – globally unique
Baumer Hübner, former Hübner Berlin, is the Baumer Competence Center for HeavyDuty encoders in drive technology. For nearly 60 years we have been world leader in this field, setting technology benchmarks for reliable encoders, tachogenerators and speed switches. They play to their strengths where conventional encoders fail. Their design is tailored to the application to ensure dependable operation you can rely on - at all times.
In 1955, Hübner Berlin developed the first encoder for the steel industry, which was tacho generator TDP 5,6 designed for roller mills. Today, the worldwide unrivaled HeavyDuty portfolio comprises absolute, incremental and bearingless encoders meeting the demanding requirements in steel plants all over the world. The HeavyDuty Competence center in Berlin implements cutting-edge production technologies.
