Switches and Hubs

Industrial Ethernet switches and network hubs connect PLCs, HMIs, drives, sensors, and IT systems on the factory floor. Unlike consumer-grade switches, industrial models tolerate vibration, electrical noise, wide temperature ranges, and the redundancy protocols (ring topology, RSTP) common in plant networks.

Enicstra stocks managed and unmanaged industrial Ethernet switches from Moxa, Cisco IE, Hirschmann (Belden), N-Tron (Red Lion), Phoenix Contact, Antaira, and similar manufacturers. Coverage includes DIN-rail unmanaged switches (5-, 8-, 16-port), Gigabit managed switches with redundant ring support, PoE/PoE+ switches for IP cameras and access points, and fiber media converters. Every switch is bench-tested before shipment with our 12-month functional warranty.

Industrial switches must match your network topology (star, ring, redundant), required port count, PoE budget, and management protocol (Profinet, EtherNet/IP). Send the OEM part number along with the application; most quote inquiries reply within 1–2 business days.

Choosing Switches and Hubs components

Industrial switch selection has more dimensions than consumer switches — power input, mounting, redundancy support, PoE budget, and managed vs unmanaged operation all matter. A 24-port managed Gigabit switch is overkill for a small machine cabinet; a 5-port unmanaged switch is inadequate for a redundant plant ring.

Specifications to confirm before ordering:

Port count and speed (10/100, Gigabit, 10 Gigabit)
Managed or unmanaged
Power supply — typically 24 VDC for industrial, redundant power input on managed switches
Mounting — DIN-rail, panel-mount, rack-mount
Temperature range (standard or extended)
Fiber ports — SFP or SFP+ slots, multimode vs single-mode
PoE support and total PoE power budget
Redundancy protocols supported (RSTP, MRP, HSR/PRP, vendor-specific ring)
Profinet/EtherNet/IP certification if connecting to industrial controllers
Security features (port-based VLAN, ACL, 802.1X)

Common configurations:

Machine cabinet: 5- or 8-port unmanaged switch, DIN-rail mount, 24 VDC
Process cell aggregation: 8- or 16-port managed switch with redundant power and ring support
Plant backbone: 16- or 24-port managed Gigabit with fiber uplinks
IP camera and access point network: PoE+ managed switch with sufficient power budget
Hazardous area: ATEX/Class 1 Division 2-rated switches

For Profinet and EtherNet/IP networks, use switches certified for the relevant protocol — generic industrial switches may pass traffic but lack the QoS and ring-handling features needed for deterministic communication.

Related categories Frequently asked questions

Can you supply discontinued Moxa or Hirschmann industrial switches?

Yes — legacy Moxa EDS-series, Hirschmann RS-series, N-Tron 500-series, and Phoenix Contact FL switches are common requests. Many remain on installed plant networks. Send the part number for availability.

Managed or unmanaged — which do I need?

Unmanaged switches work for simple star topologies where any-port-can-fail without breaking the network. Managed switches are required when you need redundant ring topology, VLAN segmentation, QoS, or remote monitoring. Most plant backbones use managed; many machine cabinets use unmanaged.

Does a switch carry PoE through automatically?

Only if it's specifically PoE-rated, and only on PoE-rated ports. PoE has a total power budget (watts) divided across PoE ports. A "PoE+ 24-port switch" might have a 200-watt budget — enough for several full-power cameras but not 24 of them. Check the budget against your device power needs.

Are these new, surplus, or used?

Most stock is new-old-stock — unused, often in original packaging. Some legacy switches come from tested system removals. Each product page lists condition where known.

What's the warranty?

All switches ship with our 12-month functional warranty. If the unit fails to perform as specified within that window, contact us for repair, replacement, or refund.
