Harting 24020050010 Ha-VIS eCon 2000 2050B-A 5-Port Unmanaged Industrial Ethernet Switch

The Harting 24020050010 Ha-VIS eCon 2050B-A is an unmanaged 5-port Fast Ethernet switch for DIN-rail mounting, built for 24 V DC or 48 V DC supply (permissible range 9-60 V DC) and an IP30 housing. It switches on all 5 10/100 Mbit/s RJ45 ports using store-and-forward technology, and runs from 0 to +55 °C operating temperature, which covers a standard control cabinet without forced cooling.

Each port auto-negotiates speed and duplex and auto-detects straight or crossover cabling (Auto-MDI(X)), so installers do not need to match cable types port by port. The switch is non-blocking across all 5 ports and supports basic quality-of-service handling and Energy Efficient Ethernet, but it has no management interface, no PoE output, and no redundancy protocol - it is a plug-and-forward device, not a configurable node on the network.

Power connects through a 3-pin pluggable screw terminal (+, -, FE) rated for 0.08-2.5 mm² conductors (AWG 28-12), with reverse-polarity protection and a 2 A input overcurrent protection built in. At 24 V DC the switch draws under 42 mA in steady state (1.01 W); inrush current on power-up stays under 2.8 A. The aluminium housing is 46.5 mm wide on the DIN rail and is rated IP30 once mated, so it still needs an enclosure against dust and moisture ingress.

Selection Notes

The 5-port 2050B-A is the smallest body in the eCon 2000 family at 46.5 mm wide, sized for a cell-level switch serving a handful of drives or I/O blocks on one machine rather than a cabinet backbone. Step up to the 2080B-A (8 ports) or 2160B-A (16 ports) when more end devices need to land on the same segment - all three share identical voltage range, port electronics, and mounting, so swapping sizes does not change the wiring or power design.
