Engineering what's next.
From advanced electronics and embedded intelligence to complete industrial solutions.
Security, trust and reliability — built into every product.
Our electronics run freight wagons, industrial machines and buildings. That is why every design is secured, every board is tested and every result is traceable.
Security
Secure by design — from firmware to cloud. Your devices, data and know-how stay protected.
- Encrypted device-to-cloud communication
- Controlled, verified firmware updates
- Confidential handling of your IP
Trust
Long-term partnerships, certified results and full transparency on every project.
- 30+ long-term partnerships
- ITRS certified by SIQ Ljubljana · NoBo 1304
- Technology partner of Schaeffler
Reliability
Every board is tested before it leaves the line. Every result is stored and traceable.
- 100 % end-of-line testing on our test stations
- 6,166 km field test with no critical faults
- Designed to EN 50155 and EN 50121-3-2
ITRS: an autonomous power grid for freight wagons.
Energy, automation and connectivity built into the wagon itself — no locomotive supply, no charging infrastructure. Developed with Schaeffler, tested on DIN EN 12082 rigs and proven on the Borlänge – Oxelösund route in Sweden.
