Overview
The Sixnet SLX-6ES-4ST is an unmanaged 6-port industrial Ethernet switch engineered for plug-and-play connectivity in harsh factory and plant automation systems. This switch is plug and play to help you save time and reduce costs. Its ruggedized, hardened design is engineered to last and offers superior performance in harsh industrial settings. The unit combines four 10/100BaseTX copper ports with two multimode fiber ports, enabling flexible network topologies for real-time deterministic operation.
Key Features
- Fast, real-time deterministic switch operation with no complicated setup involved.
- Four 10/100BaseTX RJ-45 ports and two 100BaseFX multimode 4km fiber ports with ST connectors.
- Auto-sensing speed and duplex; supports full/half duplex and MDI/MDIX crossover for universal cable compatibility
- DIN rail mounting with IP40 protection rating and metallic case construction.
- Wide supply voltage range 10–30 VDC rated for 12 VDC and 24 VDC systems.
- Compliant with UL Class 1 Division 2 Hazardous locations standards.
