Inductive sensors for the contactless detection of metal objects

Indispensable in all machines – Inductive proximity switches to monitor presence, movement and position.

Baumer is a development pioneer and one of the leading manufacturers of inductive sensors – the heart and soul of all machines. As individual items or in large quantities - we deliver standard products in various housing sizes with different sensing distances. But always with the same high quality.

These include miniature sensors with fully integrated processing electronics for applications in cramped spaces as well as especially robust sensors for outdoors and hygienic applications in stainless steel housings with high protection classes and our sealing concept proTect+. And if the standard solution doesn't fit, or to find an innovative solution for specific tasks, we can also produce individual models to customers' specifications.

We helped to create the technology, and even today we are one of the pioneers with innovative concepts.
