Why it matters now: In an era when artificial intelligence captures every trade-show marquee and boardroom conversation, a quieter but far more consequential force continues to reshape global manufacturing. Programmable Logic Controllers (PLCs), sensors, drives, and industrial control systems — the foundational building blocks of automation — are experiencing their strongest investment cycle in years, even as AI grabs the spotlight. The numbers tell an unmistakable story: the smart factory is being built not on hype, but on hardware that has been proving its value for decades.
Analyst Insight: The global industrial automation market reached an estimated $210.68 billion in 2025 and is projected to climb to $302.01 billion by 2030 at a compound annual growth rate (CAGR) of 7.5%. Within this landscape, the PLC market alone — valued at approximately $14.73 billion in 2025 — is forecast to reach $22.15 billion by 2032. These are not speculative AI-driven projections; they reflect sustained, capital-intensive investment in proven automation infrastructure.
Robot Orders Surge as Automation Investment Broadens
New data from the Association for Advancing Automation (A3) confirms that North American industrial automation is in a robust growth phase. Companies ordered 36,766 robots in 2025, representing a total value of $2.25 billion. Compared with 2024, unit orders increased by 6.6%, while revenue jumped 10.1% — a signal that buyers are not merely purchasing more units, but investing in higher-value, more sophisticated automation systems.
The fourth quarter of 2025 delivered particularly strong results, with 10,325 robots ordered at a value of $579 million. This late-year acceleration suggests momentum carrying well into 2026.

The Great Diversification: Automotive Is No Longer the Lone Driver
For decades, the automotive industry represented the gravitational center of industrial automation spending. That era is now decisively over. A3 reports that in the second quarter of 2025, non-automotive sectors accounted for 56% of total robot units ordered — capturing the majority share and reshaping the automation supplier landscape.
Life sciences, pharmaceuticals, and biomedical manufacturing led sector growth at +22%, followed by semiconductors, electronics, and photonics at +18%. Plastics, food and beverage, and general industry segments also posted steady gains. These are industries that had historically lagged in automation adoption, and their accelerated entry signals a structural shift rather than a cyclical uptick.
Market Trend: The diversification of automation end-users carries profound implications for PLC and control system suppliers. Non-automotive verticals demand modular, scalable, and interoperable control architectures — precisely the strengths of modern PLC platforms. As pharmaceutical lines, food processing plants, and electronics assembly floors automate at scale, the demand for flexible PLC-based control systems intensifies.
PLCs: The Quiet Workhorse of the Smart Factory
While collaborative robots (cobots) and AI-driven vision systems dominate media coverage, equipment manufacturers at recent trade events have centered their conversations on the technologies that actually orchestrate production: PLCs, sensors, drives, and control systems. These are the technologies that define the smart factory — not as a futuristic concept, but as an operational reality.
The PLC market's projected growth from $14.73 billion in 2025 to $22.15 billion by 2032 reflects several converging forces: the integration of IoT connectivity into control architectures, the shift toward modular and compact PLC form factors, and the growing requirement for edge-based data processing that complements — rather than competes with — cloud AI platforms.

Collaborative Robots and the Evolving Control Ecosystem
Collaborative robots represent one of the most dynamic segments within the broader automation picture. In 2025, cobot orders totaled 7,212 units valued at $241 million, accounting for 19.6% of all robots ordered. By the fourth quarter, cobots had surged to 28.6% of quarterly units — a trajectory that underscores their growing acceptance across industries that previously lacked the scale or expertise for traditional industrial robotics.
Critically, each cobot deployment depends on a PLC or equivalent controller to integrate with the broader production environment. The cobot boom is, in effect, also a PLC boom — reinforcing demand for control systems that can manage hybrid environments of traditional automation and collaborative applications.
Analyst Insight: The relationship between AI and PLCs is increasingly complementary rather than competitive. Purpose-built AI — such as vision-based quality inspection and predictive maintenance algorithms — feeds data into PLC-controlled processes. The PLC remains the executor, while AI serves as an intelligence layer. Smart factories are not replacing PLCs with AI; they are layering AI atop PLC architectures that have been refined over decades of industrial deployment.
What This Means for Industry Stakeholders
For manufacturers evaluating automation investments, the data points toward a clear strategic priority: foundational control infrastructure should precede AI experimentation. A robust PLC and sensor architecture delivers immediate operational returns — reduced downtime, improved cycle times, and enhanced traceability — while providing the data backbone that makes future AI initiatives viable.
For equipment suppliers and system integrators, the message from the market is equally clear. Buyers are allocating capital to proven automation technologies that deliver measurable productivity gains. The trade-show buzz may belong to AI, but the purchase orders are being written for PLCs, drives, and the control systems that keep factories running.
Frequently Asked Questions
Q: Are PLCs becoming obsolete with the rise of AI and cloud computing?
No. PLCs are evolving — not disappearing. Modern PLCs integrate IoT connectivity, edge computing capabilities, and open communication protocols. They serve as the real-time execution layer that AI and cloud platforms depend upon for actionable data and process control.
Q: Which industries are driving the current growth in PLC demand?
While automotive remains significant, the fastest growth is coming from life sciences, pharmaceuticals, semiconductors, electronics, food and beverage, and logistics — industries undergoing rapid automation adoption after years of relying on manual or semi-automated processes.
Q: How do collaborative robots (cobots) relate to PLC infrastructure?
Cobots require integration with broader production control systems. PLCs typically orchestrate the conveyor systems, safety interlocks, and peripheral equipment that cobots interact with, making PLCs an essential component of any cobot-enabled production cell.
The numbers from A3 and the sustained growth trajectory of the global PLC market confirm a reality that industry insiders have long understood: automation is still the leader of the pack. The smart factory of tomorrow is being built today — not on promises, but on programmable logic controllers that have earned their place at the heart of industrial progress.
