Sysmac platform expansion ideal for harsh enviornments

The Omron NJ3 series expands the Sysmac NJ series Machine Automation Controller platform to 4 and 8 axes with completely redesigned hardware, and a powerful new Intel® Atom™ processor, ideal for harsh environments. The fundamental shift from rigid ASIC architecture lets the NJ series be adaptable and scalable according to your needs. This compact controller with market leading technology provides flexibility without compromising reliability.


The NJ-Series hardware has been designed to adapt to the quickly changing demands of a machine automation controller. A typical system built around an application specific integrated circuit (ASIC) can be difficult to change and enhance. The NJ-Series uses the proven Intel® Atom™ processor to allow real-time improvements to the core of the system. This adaptability virtually guarantees a future-proof system that can lead today's automation technology and trends.

  • Unmatched CPU performance
  • Advanced embedded motion
  • Unique application solutions

Accurate and Precise

Because Omron developed every aspect of the control core, run-time is predictable and reliable with no instability caused from third party code. With this advantage, NJ-series functions can be accurately and precisely predicted for real world operation. Features such as CAM profile simulations that provide not only position data, but additionally velocity, acceleration and jerk give a detailed prediction of how the machine motion will actually perform.

  • Logic simulation
  • Motion simulation
  • Reliable operation


With a powerful processor comes multiple systems integrated into one controller. Providing advanced motion control with proven machine logic in one unit gives your machine the ultimate advantage. The NJ-Series seamlessly combines two prominent application requirements to reduce hardware and development cost. Handshaking and other intermediate steps needed with multiple systems that create overhead, inefficiency, and delay are all eliminated while functionality and performance are increased. Tying in vision via the built-in EtherCAT interface, configured from the same software environment as the logic and motion, makes the solution unprecedented. All logic, motion, I/O, and vision response refreshing are all executed in the same control period. This enables precise sequence and motion control, in-sync with machine vision, all within a fixed period with minimal deviation.

  • One Controller: Tightly integrated logic, motion, and vision without sacrificing performance
  • One Software: Integrated Development Environment for logic, motion, and vision
  • One Connection: Single connection point into every aspect of the machine


Building on Omron's reputation for quality and innovation, the NJ-Series is designed to be a solid performer in the class of machine automation controllers. All Omron hardware undergoes stringent industrial environment testing. Fan-less operation with efficient heat dissipation eliminates mechanical failure and extends the life of the system. Standard Ethernet and USB Ports provide familiar interfaces for connection and communication. An SD memory card slot integrated in the CPU provides a common media for data storage. Backwards compatibility is provided with most CJ type IO units for easy upgrade and a full range of available and existing unit types.

  • Class leading industrial-grade unit with compact size
  • Standard feature Ethernet/IP and EtherCAT Master ports
  • Backward compatibility with existing Omron CJ type IO & units


Developed from years of experience, the NJ-Series combines the newest technology with the stability and reliability of traditional PLCs. Built upon the knowledge and success of previous controllers, the NJ-Series advances with improvements such as task scheduling, centralized error handling, synchronized control, and multitasking. The NJ-Series system provides the hardware reliability that you expect from a PLC with the flexibility and power of a machine automation controller.


The NJ-Series is based on standard IEC 61131-3 programming languages and structures. An extensive instruction set following IEC rules and PLCopen based motion control is provided. Hardware compliance with EMC and EC directives ensure your system will operate according to widely accepted regulations. Global standards conformance combined with Omron's extensive worldwide support network allows your machine to comply with a variety of international markets without limitations.
