SPR20-7TX/2FS-EEC – Unmanaged Industrial Ethernet Switch by Hirschmann, a Belden Brand

The Hirschmann SPR20-7TX/2FS-EEC is an unmanaged industrial Ethernet rail switch from the proven SPIDER III family, designed to provide reliable, plug-and-play Fast Ethernet connectivity in demanding industrial environments without the need for configuration tools or software setup. Part number 942335031, the switch provides seven auto-crossing, auto-negotiating, auto-polarity 10/100BASE-TX RJ45 twisted-pair ports with a reach of up to 100m, alongside two 100BASE-FX single-mode fibre ports using SC connectors capable of spanning up to 30km at 1300nm, making it well suited to network extensions across large industrial sites, railway lineside cabinets, and substations. The store-and-forward switching architecture ensures data integrity, and the software feature set includes Ingress Storm Protection, Jumbo Frames support, and QoS port prioritisation to IEEE 802.1D/p for traffic management. Operating from a redundant 12/24V DC supply accepting 9.6V to 32V DC with a maximum power draw of 6.9W, the SPR20-7TX/2FS-EEC is well suited to DIN rail installations in panel enclosures powered from standard industrial supply voltages. The IP40 metal housing provides mechanical protection, while IEC 60068-2-6 vibration and IEC 60068-2-27 shock compliance ensure robust performance in transportation and industrial environments. The switch carries an impressive MTBF of over 2.6 million hours at 25°C and a 60-month guarantee, underpinning its suitability for long-term critical infrastructure deployments. Regulatory approvals include CE, FCC Class A, EN61131, cUL 61010-1/61010-2-201, ISA 12.12.01 Class 1 Div. 2 ATEX Zone 2 hazardous location certification, DNVGL shipbuilding approval, EN50121-4 railway norm, and E-Mark transportation approval.
