3-port industrial-grade switch

Industrial 3-port Ethernet switches provide rugged, reliable connectivity with RJ45 and SFP ports, suitable for harsh environments and industrial applications.

Key Features

Ports and Connectivity: Most 3-port industrial switches include 3 RJ45 copper ports (10/100/1000 Mbps) and 1 SFP fiber port supporting 100Base-FX or 1000Base-X with auto-detection, enabling hybrid copper-to-fiber networks for extended reach and noise immunity. Auto MDI/MDIX and full/half-duplex support simplify deployment without crossover cables. Power and Voltage: These switches typically support wide DC input ranges (12–48V), with some models offering redundant power inputs and PoE capabilities (IEEE 802.

3af/at) to power connected devices like IP cameras or access points. Environmental Tolerance: Designed for industrial use, they operate in extreme temperatures from -40°C to +75°C or higher, with IP30–IP40-rated aluminum or metal enclosures for EMI protection and durability. Fanless designs reduce maintenance and improve reliability.

Mounting Options: Compact form factors allow DIN-rail or wall mounting, making them suitable for space-constrained installations in factories, transportation systems, or utility monitoring points. Performance and Standards: These switches offer store-and-forward processing, switching capacities around 8–16 Gbps, and support IEEE 802. 3az Energy Efficient Ethernet to reduce power consumption.

Some models include QoS, jumbo frame support, and industrial-grade chipsets for stable, low-latency performance.
