SSL20-4TX/1FX – 5-Port Unmanaged Fibre DIN Rail Switch by Hirschmann, a Belden Brand

The Hirschmann SSL20-4TX/1FX is a five-port unmanaged industrial Fast Ethernet switch from the SPIDER III family, combining four auto-crossing, auto-negotiating 10/100BASE-TX RJ45 copper ports with one 100BASE-FX multimode fibre port via SC connector, making it an ideal local access switch with a fibre backbone uplink for machine-level and panel-level Ethernet networking. Identified by product code SPIDER-SL-20-04T1M29999SY9HHHH and part number 942132007, the switch supports multimode 50/125µm fibre distances up to 5000m with an 8dB link budget at 1310nm, and 62.5/125µm multimode fibre up to 4000m with an 11dB link budget at 1300nm, enabling flexible fibre infrastructure integration across a wide range of industrial sites. Each of the four copper ports supports auto MDI/MDIX crossing and auto-negotiation, requiring no manual configuration for Ethernet link establishment. Store-and-forward switching ensures data integrity across all five ports. Power is provided via a 3-pin terminal block accepting 12/24V DC at 9.6V to 32V DC with a maximum consumption of 2.4W at 100mA draw at 24V, keeping panel heat contribution minimal. The operating temperature spans 0°C to +60°C, and the MTBF is rated at 2,286,711 hours under Telcordia methodology. The compact IP30 DIN rail plastic housing measures 26 x 102 x 79mm and weighs 120g. Industrial EMC immunity to IEC 61000-4-2 through 61000-4-6, along with CE, FCC Class A, EN61131, and cUL 61010-1/61010-2-201 approvals, confirms compliance across industrial installation requirements. IEC 60068-2-6 vibration and IEC 60068-2-27 shock compliance add mechanical robustness. A 60-month guarantee is included.
