SSL20-6TX/2FX – 8-Port Dual Fibre Unmanaged Switch by Hirschmann, a Belden Brand

The Hirschmann SSL20-6TX/2FX is an eight-port unmanaged industrial Fast Ethernet switch from the SPIDER III family, combining six auto-crossing, auto-negotiating, auto-polarity 10/100BASE-TX RJ45 copper ports with two 100BASE-FX multimode fibre ports via SC connectors, distinguishing it from the single-fibre-port variants by enabling dual fibre uplinks for ring topologies, redundant backbone connections, or cascaded network segments. Identified by product code SPIDER-SL-20-06T1M2M299SY9HHHH and part number 942132012, both multimode fibre ports support 50/125µm fibre distances up to 5000m with an 8dB link budget at 1310nm and 62.5/125µm fibre up to 4000m with an 11dB link budget at 1300nm, allowing engineers to design flexible and resilient industrial Ethernet topologies across large factory floors, process plants, and building automation systems. All six copper ports use auto MDI/MDIX for plug-and-play copper connectivity, and store-and-forward switching ensures data integrity across all eight ports. Power is from a 3-pin terminal block accepting 12/24V DC at 9.6V to 32V DC with a maximum of 3.8W and 160mA at 24V DC. The operating temperature is 0°C to +60°C, and the MTBF is 1,499,396 hours under Telcordia methodology. The DIN rail IP30 plastic housing measures 45 x 110 x 88mm and weighs 230g. EMC immunity covers EN 61000-4-2 ESD, EN 61000-4-3 at 10V/m, EN 61000-4-4 burst, and EN 61000-4-5 surge. CE, FCC Class A, EN61131, and cUL 61010-1/61010-2-201 approvals apply. A 60-month guarantee is included. Available from Recab, your Nordic partner for Hirschmann industrial Ethernet switch solutions.
