Data Transmission

For the transmission of digital video, audio, and informational data in real-time networks (e.g., IP-based Ethernet or fast Ethernet networks), optical radio relay system contact systems (era transceiver) or coaxial male/female contact systems are used.

With these integrated contact systems, signals and data are transmitted without signal loss in real time in a train of rail vehicles from one vehicle to the other (several coupled multiple units) or in locomotive-hauled trainsets.

Owing to the galvanic separated transmission, the signals to be transmitted are impervious to electromagnetic disturbances. This means that the system is also suited for transmitting security-relevant signals in train bus systems.

The technology used also permits the transmission of signals over stretches of open space. Thus, no physical contact is necessary to transmit signals.

With the aid of the multiplex system, next-generation electrical couplings for high-speed trains, electrical multiple units (EMUs) and diesel multiple units (DMUs), light rail vehicles (LRVs), and metros are much smaller and lighter.

The system can also be employed in hand couplings and jumper cables.

In electrical train couplings, special contacts for the transmission of sensitive signals such as WTB/MVB and CCTV have proven to be effective. This contact principle is meant for connecting shielded cables and is designed for 50,000 mating cycles.
The coaxial contact principle concerns shielded individual connections to transmit signals with a high data rate in 1-, 2-, and 4-pin (plus shield) versions. The connection takes place over gold-plated male/female (pin/socket) contact terminals. The shield is transmitted over the entire contact system; this is true for the actual points of contact as well. This permits a minimal resistance at the junction with maximum shielding.

In comparison to those of most providers, our contacts are exchangeable from the start for simple and secure maintenance.
That saves you time and money.
We offer you whichever cable retention connection you need: a crimped, threaded (screw-on), or plug-in connection.
