CAN SAE J1939® – One standard across mobile off-highway machinery

With CAN SAE J1939 control you get an all-in-one package solution. LINAK® actuators with built-in CAN bus are easy to install and adjust to fit a wide range of heavy-duty machinery.


What is CAN SAE J1939?

CAN SAE J1939 is a standardised method developed by the Society of Automotive Engineers (SAE) for communication across Electronic Control Units (ECU) – offering a common language for all manufacturers. CAN SAE J1939 provides a Higher Layer Protocol (HLP), which is based on the physical Controller Areas Network (CAN) layer.

The protocol has been on the market for decades and is widely used in mobile off-highway machinery for construction, material handling and forestry machines to support smart automation.


LINAK actuators with integrated SAE J1939 CAN bus

In modern farming, construction and mobile outdoor applications, requirements for machinery control are crucial.

The solution is electric and includes advanced BUS communication. LINAK therefore paves the way for a more automated and autonomous world, offering several actuators with integrated SAE J1939 CAN bus control – all covering a wide range of options when it comes to size and power.

CAN SAE J1939 is part of our IC Integrated Controller™ programme and with this well-known bus standard, you can use linear actuator movement in your CAN bus system without having to use customised electronics.

Actuators with built-in CAN bus control are easy to install and adjust to fit a wide range of heavy-duty machinery within, for instance, agriculture and construction. Increased connectivity and live data make it easy for a control system and actuators with CAN bus to communicate directly with each other.


Easy integration and adjustment options

With few components and simple wiring, our range of CAN SAE J1939 actuators give you a hassle-free installation and connection to the existing CAN bus network in your machine. Furthermore, each actuator type can be adapted to different functions for the same machine with just a minor parameter change.


Features and advantages

With this bus standard, the actuator provides information for planning maintenance, diagnostics and troubleshooting, which cuts service costs significantly.

In addition to full position control, the CAN bus actuator can provide feedback information about the piston position, service data and full diagnostics.

Features of actuators with CAN SAE J1939





Hardware and software addressing

Generation of seven unique CAN addresses by a simple pin configuration change. The result is fast installation and replacement, and you can even use the same actuators for several purposes.

The software CAN address assignment can be achieved using the LINAK service tool or the J1939 diagnostics.


Dynamic speed adjustment

Speed variation throughout the actuator movement and direct read-out of speed on the CAN bus network.


Soft start and stop

Soft start and stop times can be set directly using a CAN command. You can set a ramp time for a smoother run to reduce mechanical stress on your machinery.


Increased compatibility

A wide range of fixed communication speeds in addition to Autobaud for increased compatibility with various machinery.



The benefits of actuators with integrated CAN SAE J1939 are numerous

  • Check real-time position of the actuators
  • Monitor their status feedback such as speed, run-time, current and other conditions
  • Full diagnostics and service overview, including both current and historic data
  • Fewer components and simple wiring, easy to integrate in your machine
  • Increased flexibility for adapting the same actuator to fit various types of applications
  • Service data allows for faster troubleshooting and maintenance
