4-Port Switch Industrial Grade

Industrial-grade four-port switches provide robust, high-speed Ethernet connectivity with PoE support, SFP uplinks, and ruggedized designs for harsh environments.

Key Features

Port Configuration and Connectivity: Most industrial four-port switches offer 4 RJ45 Gigabit Ethernet ports for high-speed data transmission, often combined with 2 SFP ports for fiber-optic uplinks, enabling long-distance communication and low-latency connections suitable for industrial backbone networks (Comxus, AXIS, FR-6S3204) . Power over Ethernet (PoE): Many models support IEEE 802.3af/at or PoE+ standards, allowing devices like IP cameras, wireless access points, VoIP phones, and sensors to receive power directly through Ethernet cables, eliminating the need for separate power supplies and simplifying installation (Comxus, PLANET IGS-514PT) . Ruggedized Design: Industrial switches are built to withstand extreme temperatures (-40°C to +85°C), vibration, dust, and electrical interference, often featuring metal enclosures and DIN-rail or wall mounting for installation in control panels, cabinets, or outdoor environments (Comxus, AXIS, FR-6S3204) . Management and Network Features: Managed switches provide Layer 2 functionalities such as VLAN, QoS, RSTP, Spanning Tree, and network monitoring tools. Some models include web-based GUIs, integrated DHCP servers, and smart PoE management for remote troubleshooting and power optimization (AXIS T8504-R, Comxus) . Power and Performance: Industrial PoE switches can deliver up to 30–120 watts total PoE power, supporting multiple high-power devices simultaneously. Some models offer redundant DC power inputs for operational reliability (PLANET IGS-514PT) . Applications: These switches are ideal for industrial automation, surveillance systems, smart transportation, oil & gas facilities, and IoT deployments, providing a stable and scalable networking backbone for mission-critical devices (Comxus, Moxa) .
