Two thousand meters underground; on offshore platforms; in faraway solar installations. But also in the quiet reliability of everyday systems: the switches that simply work, the connections you never think about. This is where our engineering proves itself. Where reliability becomes everything.

For over eight decades, we've been the engineers, designers and technicians who master applications that work when and where they must. As a family-owned company, we've built our reputation on the world's most demanding requirements.

We design with purpose, so every detail delivers performance, safety, and intuitiveness. From the factory floor to the final product, we make complex things work.

While others pursue theoretical breakthroughs in laboratories, we innovate through real-world problem-solving. We build applications that don't just perform. They become indispensable.

Generation after generation. Installation after installation.

Katko. Built for what can't fail.
