The Hirschmann BOBCAT BRS20-20TX/4SFP-EEC is the wide-temperature, high-density variant of Hirschmann’s 24-port BOBCAT managed switch family, developed by Hirschmann, a Belden brand, for industrial environments where extreme temperatures, vibration, and EMC stress are standard operating conditions. The switch combines 20x 10/100BASE-TX RJ45 copper ports with four 100 Mbit/s SFP slots in two dual-SFP uplink groups, supporting single-mode, long-haul, and multimode fiber types to accommodate long-distance inter-cabinet and ring backbone connections in large facilities or outdoor plant. Its metal DIN rail housing, fanless design, and -40 to +70°C operating range make it specifically suited to railway traction and wayside control systems, outdoor power substations, wind farm networks, heavy manufacturing, and other demanding field infrastructure across Nordic and Baltic environments. Time-Sensitive Networking (TSN 802.1Qbv) on interfaces 1/1 to 1/3 provides the deterministic Ethernet scheduling needed by coordinated motion control, machine safety systems, and IIoT-integrated automation platforms. Network resilience is assured through HIPER-Ring, MRP (IEC62439-2) as both client and manager, RSTP, LACP Link Aggregation, Link Backup, and Redundant Network Coupling. PROFINET, EtherNet/IP, Modbus TCP, and IEC61850 protocol support provides compatibility with major PLC, SCADA, and protection relay systems across automation, energy, and infrastructure sectors. Cybersecurity capabilities include Secure Boot, signed firmware, 802.1X port access control, RADIUS authentication, VLAN-based ACLs, and DoS prevention. Vibration compliance per IEC 60068-2-6 and shock compliance per IEC 60068-2-27, alongside an MTBF of approximately 2.31 million hours and a 60-month guarantee, confirm this switch as a dependable long-lifecycle solution for the harshest industrial deployments.
