The STG-Germany Group is one of the leading manufacturers of reed switches and sensors.
We offer over 800 standard products worldwide. Furthermore, we carry a multitude of custom made
products and articles which are specially designed and supplied to the individual needs of our customers

At STG, we do not make compromises when it comes to quality control in all of our processes. Our target is “zero defect” from the very beginning.

The "zero defect" policy stipulates that no defective materials should enter the production lines and that no non-conforming intermediate products or finished products should be passed to the next stage. Check points for error detection are installed at critical stations throughout the manufacturing process.
