Kontron is presenting a new railway-compatible Ethernet switch at the InnoTrans 2024 trade fair in Berlin, which offers maximum flexibility in terms of the number of individually required Ethernet ports and performance from Fast Ethernet to 10GbE thanks to its modular design. Designed and manufactured in Europe, the KSwitch R20 with robust push-pull M-12 connections enables interference-free data transmission even under difficult conditions, such as use in public transport, where vibrations, shocks, extreme temperatures or temperature fluctuations can occur.

The highly scalable and PTP-capable (Precision Time Protocol) KSwitch R20 enables TSN (Time Sensitive Networking) applications and the flexible, modular use of up to 28 Power-over-Ethernet ports with 100Mbit/s / 1 / 2.5 / 5 / 10 GBit/s and thus an individually scalable bandwidth utilisation of up to 6Gbps. The fanless Ethernet switch was developed in compliance with EN50155, i.e., suitable for railway applications, and offers particularly high shock and vibration resistance. With its extremely robust design and the possibility of operation in an extended temperature range between -40 °C and +70 °C (+85 °C for a maximum of 10 minutes), the fanless KSwitch R20 is therefore suitable for particularly demanding applications in the railway environment, such as rolling stock.

Increasing network security requirements are already taken into account in the design with secure configuration management via SSH, an encrypted configuration dongle and a secure operating system. Thanks to the high bandwidth with PTP support, the KSwitch R20 is designed for a broad data throughput and time-synchronised operation. All management switching and routing features, such as unicast/multicast switching, forwarding, VLANs, IGMP snooping and querying etc. are supported. The KSwitch R20 module can be monitored via SNMP over a serial line or Ethernet. Web-based management and a comprehensive command line interface enable layer 2/3 management including full IPv6 support. Functions such as IP forwarding & multicast, routing & switching, quality of service, VLANs etc. enable complex network routing.

The KSwitch R20 can be operated in line with 24VDC to 110VDC +/- 20% and supports up to 90W PoE power, which can be flexibly distributed to the ports. This means that small consumers, such as cameras or operating terminals, can be supplied directly. Up to 600W PoE power can be distributed to the ports via an additional power feed. The modular concept allows any configuration based on FE (Fast Ethernet), GbE or 10GbE modules, which can be used to realize customized solutions in addition to the standard KSwitch R20 configurations.
