Technical upgrading without extensive modifications

When modernization projects arise, the components originally used are frequently no longer available or no longer meet current technical requirements. As a result, vehicle operators repeatedly need to replace passive sensors with active sensors in order to supply modern train control systems with reliable speed signals.

Form-fit-function replacement solutions help bring rail vehicles up to the latest state of the art without extensive design modifications, enabling continued operation and significantly extending the service life of the vehicle.

Modernization without design modifications

When modernizing the electronics and control systems of rail vehicles, increased technical requirements must be met. However, the existing installation space generally remains unchanged.

A leading Swiss manufacturer of rail vehicles uses our threaded sensors to integrate current technology, such as a reliable 0 Hz standstill detection.

Thanks to standard thread types and nominal lengths as well as custom cable assemblies, the space-saving sensors can be easily integrated into existing designs without any mechanical modifications.

Increased safety in regional transport

To ensure high safety standards, state-of-the-art sensor technology is deployed. In the course of introducing the Positive Train Control (PTC) automatic train protection system, or in ETCS projects, complete fleets are being retrofitted with our bearing-free rotary encoders and axle encoders.

These sensors provide additional data channels and supply control systems with precise information in real time. The transition from passive to active sensors not only increases reliability, but also creates the foundation for more efficient and even safer rail operations.

Form-fit-function over decades

Ensuring the long-term availability of bearing-free rotary encoders is particularly challenging for manufacturers and operators, especially for sensor solutions with non-standard housings, connectors or signal configurations. If the previous supplier fails, manufacturers and operators must quickly find a replacement supplier. This supplier must be able to deliver the custom design and possess the necessary technical expertise as well as knowledge of certification requirements.

We are your experienced partner for the development and certification of 1:1 replacement solutions. With in-depth know-how in certification processes and proven, robust sensors, we offer you fast, reliable and cost-efficient alternatives. Thousands of successful deployments guarantee the availability and safety of your vehicles.
