Although construction and agricultural machines, trucks and buses look like big bruisers from the outside, they are really high-tech products on wheels. Thanks to electronic control units their control and safety applications have become ever more complex. The high quality demands found in this sector result not least from the harsh environments encountered – whilst at the same time the quantities involved are very small and the variety enormous.
SAE J1939
To meet the demands of the on- and off-highway industry for communication systems suitable for their applications, Kübler has implemented SAE J1939 – the standard protocol of the Society of Automotive Engineers, for commercial vehicles and ships, railway vehicles, construction and agricultural machinery. This has been achieved primarily on the basis of CANbus and by networking system components on a standardised basis, whilst at the same time offering manageable costs, flexible communication options and compatible components.
Kübler Sendix encoders with the SAE J1939 interface
The Kübler Sendix encoders with the SAE J1939 interface and 14 Bit resolution support virtually all common requirements of the special protocol and make an essential contribution to the overall system diagnostics or to the quick localisation of failures.
SAE J1939 was integrated in the proven type M3658 and M3678 magnetic absolute CAN encoders and ensures a smooth-running exchange of information between individual sub-systems – whether it is a matter of current rotational speeds in construction machinery or of idling speed under load for lifting platforms.
SAE J1939 combines all the incoming signal data into specific parameter groups (PG), which means that these encoders can be adapted to virtually all customised applications that have an integrated J1939 protocol.
Safety and protection
In accordance with the protected Kübler Safety-Lock plus technology, the encoders boast especially sturdy bearing assemblies with interlocked bearings. Furthermore, the Sensor-Protect technology with its fully encapsulated electronics and separate mechanical bearing assembly ensures the very high protection rating IP69K.
