Certified quality and competence.
 |
As applications grow more complex, the dependability of partners and long-term confidence in the technology become ever more important. For some 30 years we have participated actively in the standards committees of international organisations such as IEC, IEEE, VITA and PICMG. Thus we remain abreast of worldwide standards and you can be sure to profit from the latest technologies. Plus Schroff is certified to ISO 9001, ISO 14001 and OHSAS 18001 and has been for many years. |

Mobile - and secure.
 |
In railway systems the highest security has absolute priority. A failure in sensitive equipment can have catastrophic consequences. Our products thus fulfil the demanding railway standards concerning mechanical stability, shock, vibration and EMC, whether they are standard components or custom developments. The trust and satisfaction of our customers are the proof of this. |
