Your Train Must Stop with Millimeter Accuracy at Every Station
Metro trains must stop with millimeter-level precision at every station to ensure perfect synchronization between train doors and platform screen doors. Even a slight positioning error can delay door synchronization by a few seconds, enough to disrupt operations across an entire line during peak hours. This requirement becomes even more critical on fully automated networks operating without drivers.

Our Sensing and Measurement Technologies
Magnetic Rings
We develop and manufacture magnetic rings combining a metal carrier with an elastomer compound loaded with magnetic particles. When paired with a sensing probe, they provide precise speed and position data from the wheelset of your metro train.
Their durability, bond strength, and measurement accuracy make them equally suitable for industrial and high-speed rail applications.
Absolute Angle Sensor
Our absolute angle sensor is based on eddy-current technology and operates within a frequency range of 2 to 5 MHz.
Its extremely low latency enables precise absolute angular position measurement, providing a direct benefit for platform screen door synchronization and train positioning systems. The technology was showcased at the international InnoTrans exhibition, the leading event dedicated to the global rail industry.
