Omron Industrial Automation: PLCs, Safety Systems, and Servo Drives

Omron Corporation is one of the world's most enduring and technically diverse industrial automation manufacturers, with a history spanning more than nine decades. Its programmable logic controllers, safety automation systems, servo drives, sensors, and industrial robots have been integrated into manufacturing operations across every major industrial sector. When production equipment built on Omron control platforms requires replacement components, particularly for systems that predate Omron's current product line, K2 Automation is the specialist supplier that engineering teams rely on. We stock Omron parts across the full range of the company's legacy and current catalogue, including components that are no longer available through Omron's own distribution network.

What Is the History of Omron Corporation?

Omron Corporation traces its origins to 10 May 1933, the date Kazuma Tateishi established the Tateisi Electric Manufacturing Company in Osaka, Japan. The company began with a timing device for X-ray equipment, a precise electromechanical switch that limited exposure duration. From that founding application in precision timing, Tateishi expanded the company's product range through protective relays, micro switches, and industrial control components throughout the 1930s and into the post-war reconstruction period.

In 1950, the company resumed full-scale operations from its Kyoto facilities under the name Omron Tateisi Electronics, taking the 'Omron' prefix from Omuro, the area of Kyoto where it was based. During the early 1950s, Kazuma Tateishi toured American industrial facilities and came away convinced that an automation revolution was approaching in Japan. He reorganised the company around that conviction, introducing the Producer System, a decentralised management structure that delegated operational responsibility to individual product lines and gave the company the agility to develop new technologies quickly.

The decade that followed saw Omron develop the world's first non-contact switch in the 1950s, an automated traffic signal control system in 1964, and the world's first electronic ticket gate in 1967, an invention recognised as an IEEE Milestone in 2007. The company's ability to translate precision electromechanical engineering into emerging electronic technologies made it consistently competitive as industrial automation evolved.

Through the 1980s and into the 1990s, Omron cemented its position in industrial automation with the introduction of its programmable logic controller product lines. The C series PLCs, followed by the CJ and CS series, became widely adopted platforms for mid-range industrial control. The company's CX-Programmer software environment and the NX/NJ machine automation controller series represent the current generation of Omron's PLC offering, but the installed base of earlier Omron control hardware remains substantial in facilities worldwide.

Omron's safety automation portfolio developed in parallel with its mainstream automation products. Safety relays, safety PLCs, light curtains, and safety-rated I/O modules established Omron as a serious supplier to machine builders who needed IEC 62061 and EN ISO 13849 compliant control systems. The company's vision of the relationship between machines and people, expressed in its long-standing motto 'To the machine the work of machines, to man the thrill of further creation', has guided its product development philosophy for decades.

What Omron Products Does K2 Automation Supply?

K2 Automation's Omron inventory spans the principal product categories that Omron supplies to industrial customers. This includes Omron programmable logic controllers from the C, CJ, CS, and CP series, together with associated I/O modules, communication modules, power supplies, and programming cables. Many C series units, including C20K, C200H, and CQM1 variants, are no longer manufactured by Omron and can only be sourced through specialist suppliers.

Servo drives and servo motors from Omron's range are a significant part of the inventory. The Accurax G5 series, the SmartStep series, and earlier Omron servo platforms are all represented. Because Omron's servo range shares design lineage with the Yaskawa Sigma series (Omron and Yaskawa have had a long-standing OEM partnership in servo products), there is considerable cross-referencing expertise within K2 Automation's technical team.

Safety automation components are another key area. Safety relays from Omron's G9SA and G9SP series, safety-rated light curtain controllers, and safety I/O modules are all stocked. These components sit in machine safety circuits, and their failure or obsolescence in an existing machine can create both operational and compliance challenges that require immediate resolution.

Human Machine Interface products, including Omron's NS and NB series touchscreen terminals, are also part of the K2 Automation Omron inventory. HMI units are frequently the first component to fail in older equipment, and their obsolescence can make them the most difficult part to source through standard channels.

Why Does Obsolete Omron Hardware Remain Critical to Production Facilities?

Industrial control hardware has a service life that typically extends well past the end of manufacturer support. An Omron C200H PLC installed in the early 1990s may still be controlling a press, conveyor, or processing line that was built around it and has never warranted a controls upgrade. The machine continues to function, but the spare parts to keep it operational are no longer available from Omron. When a module fails, the choice is a secondary market source or a full controls replacement project.

Controls replacement projects are not trivial. They require engineering assessment, new hardware procurement, software development, site commissioning, and production downtime. For a facility running at high utilisation, the cost and disruption of a controls upgrade can far exceed the value of keeping the original hardware operational through secondary market sourcing. K2 Automation exists to serve precisely this need: providing verified, tested Omron components that allow engineering teams to restore production without the delay and cost of a capital project.

What Industries Rely on Omron Automation Components?

Omron's industrial presence is particularly strong in sectors where precision sensing, safety compliance, and programmable control interact closely. The automotive industry uses Omron sensors, PLCs, and safety components extensively in body shop, assembly, and testing operations. The electronics and semiconductor manufacturing sectors depend on Omron's vision systems and precision sensing for quality control and process monitoring.

Food and beverage manufacturing is another core Omron application sector, where hygienic design sensors, temperature controllers, and safety systems operate continuously in demanding environments. Pharmaceutical manufacturing uses Omron's automation and safety products in process control and compliance-critical applications. The packaging machinery sector, machine tool industry, and logistics automation sector are all significant consumers of Omron PLCs, servo drives, and safety components.

How Can K2 Automation Help When Omron Parts Are No Longer Available?

When an Omron component reaches end-of-life status and disappears from Omron's own channels, K2 Automation's global sourcing network is activated to find it. Our team works from a controlled supply chain that sources verified stock through specialist contacts across multiple continents. Lead times depend on the specific component, but for machine breakdown situations, K2 Automation prioritises emergency sourcing with same-day delivery available where stock is confirmed.

For customers facing a machine breakdown with no immediately available part, K2 Automation also offers an exchange service. A refurbished, tested unit is despatched in exchange for the customer's defective part, providing a rapid restoration of production while the defective unit is assessed. This model is particularly valuable for high-cost items like servo drives and HMI units where waiting for a repair may be impractical.
