The Hirschmann BOBCAT BRS40-16TX/4SFP-EEC is the Extended Environmental Class variant of the BRS40 all-Gigabit managed DIN Rail switch, engineered specifically for industrial installations where ambient temperatures range from -40 to +70°C. Part number 942170066, it offers 20 ports combining 16 x 10/100/1000BASE-TX RJ45 copper ports and four SFP slots accepting 100 or 1000 Mbit/s fiber modules, including single-mode, long-haul, and multimode types for maximum installation flexibility. The BRS40-EEC is built on Hirschmann’s TSN-capable BOBCAT platform, supporting IEEE 802.1Qbv Time-Sensitive Networking to enable deterministic, low-latency communication across industrial Ethernet backbones. The metal housing and EEC-rated design make it suitable for outdoor cabinets, railway lineside equipment, and harsh manufacturing environments where standard switches cannot operate reliably. Network resilience is provided through HIPER-Ring, MRP (IEC62439-2), RSTP, and LACP link aggregation. Industrial protocol support includes PROFINET, EtherNet/IP, IEC61850, and Modbus TCP, while the security stack covers 802.1X, RADIUS, secure boot, signed firmware, and DoS prevention. Power is supplied via dual redundant 12–24 VDC inputs and management via USB-C, HTML5, CLI, and SNMP. The BRS40-16TX/4SFP-EEC is the preferred choice for engineers specifying all-Gigabit switches for outdoor, railway, energy, and heavy industrial applications demanding extended temperature ratings.
