Kübler pulses for the heavy industry. Reliable and sturdy.
On oil platforms and offshore plants, in open-cast or underground mining machines, in crane installations and in steel plants - Kübler encoders operate reliably in heavy machinery in the harshest environmental conditions
with dust, moisture and extreme temperatures and mechanical stress. Usually, in these unfriendly environments, high-accuracy sensors reach their limits.
This is not the case with Kübler - With its wide-ranging products portfolio, the Company boasts more than 50 years of experience in mechanical engineering and automation technology.
Heavy Duty encoders and rugged compact encoders equipped with particularly robust bearings, wit the most modern housing technologies and many various communication interfaces
(from analogue up to the real-time Profinet interface) are part of our wide heavy industry-specific products range.
Encoders for functional safety and optical fibre modules for the secure optical transmission of encoder signals over long distances complete the Kübler product range for these application fields.
Positioning and speed measurement for heavy cranes: Availability 24 hours a day
Gantry crane, container loading bridge crane, stacking crane... the requirements for automation and safety are increasing. Sendix encoders measure the position at the rope hoisting gear, at the trolley, both on rails and on tyres, and at the spreader. Only these robust and safe measuring devices allow the automatic positioning of the containers.
The lifetime and availability of the used sensors is of outmost importance for plants with high operating costs. For decades, Kübler sensors provide highest performances for gantry cranes in harbours and for underslung cranes in production lines or steel plants.

Technologies for the heavy industry
Innovations from tradition. Kübler products benefit from 50 years experience in automation engineering. Over the years they have undergone ongoing development and been optimised for use in the heavy industry. Small details make a big difference. Our products feature many intelligent, high-quality extras, which offer our customers decisive advantages, whilst at the same time making a significant contribution to the high availability and safety of the machines.
Optical Multiturn Technology
100 percent resistant to magnetic fields - extremely compact design. Even strong magnetic fields, as occur in the vicinity of brakes or drive motors, pose no problems for the sensor technology of optical single- or multiturn devices. The technology dispenses with any components that may be susceptible to magnetic influences. As a result of the proven drive, the encoder has no need of a battery to store the number of revolutions.
Insensitive to interference: OptoASICs
The resistant Kübler OptoASIC technology offers a very high integration density of components. This means that, on the one hand, the reliability in the application can be increased significantly, and on the other hand the technology demonstrates quality EMC characteristics and shock resistance.
Well protected against dust and moisture
The sturdy, thick-walled die-cast housing of the Sendix encoders is press-fit stemmed several times on the encoder flange. The high protection level and the wide temperature range from -40°C to +90°C allow a safe outdoor operation. The die-cast housing is fitted with an extremely resistant base, on which the connector flange is screwed with four screws.
High temperatures
High heat resistance - combined with high rotational speeds - make the Sendix encoders the optimal solution for all applications in a high temperature environment. Also the used seals, cables and connectors withstand extreme temperatures.
Shock and vibration resistant
Kübler encoders avoid serious, expensive failures right from the start - even with increased levels of axial loading, shock and vibration. This can eliminate enormous service costs and expensive downtimes in applications worldwide.
Sea-water resistant versions
Although it has already proved itself in harsh environments, the Sendix family of devices has now been tested and certified to IEC 68-2-11 for resistance to the effects of salt-spray over a period of up to 672 hours - the highest test level. The high certification level for the Sendix encoders attests a high level of corrosion resistance.
