PoE modules and PoE switches deliver both power and data over a single Ethernet cable, supporting IEEE 802.3af/at/bt standards for flexible network deployment.

PoE Modules

PoE modules are compact devices that allow networked equipment to receive power through Ethernet cables without separate power supplies. They are available in Single In-Line (SIL), Dual In-Line (DIL), and Surface Mount (SMT) packages and provide output voltages such as 3.3V, 5V, 12V, or 24V with overload, short-circuit, and thermal protection . Modules are designed for Powered Devices (PD), which extract power from standard Cat5e/6a cables, and Power Sourcing Equipment (PSE), which supplies power to connected devices. PoE modules support PoE, PoE+, and PoE++, delivering up to 99W per channel with high-efficiency DC-to-DC conversion . They are widely used in IoT, industrial automation, security, AV, and commercial electronics.

PoE Switches

PoE switches integrate multiple Ethernet ports with built-in PoE capabilities, allowing devices like IP cameras, access points, and industrial sensors to receive both data and power over a single cable. They come in managed and unmanaged versions, with port counts ranging from 5 to 48 or more . Industrial-grade PoE switches provide surge protection, extended temperature operation (-40°C to +70°C), and ring redundancy for reliable communication in harsh environments . Smart PoE management features simplify deployment and maintenance, while high-power ports (up to 90W per port) support high-demand devices .

Key Benefits

• Reduced cabling: Eliminates the need for separate power lines, saving installation time and cost .
• Flexibility: Devices can be placed in locations without nearby power outlets .
• Scalability: Easily expand networks by adding PoE-enabled devices without additional infrastructure .
• Safety and reliability: Built-in protections prevent damage from overloads or short circuits .

Applications

PoE modules and switches are ideal for industrial automation, security systems, smart buildings, and IoT networks, where both power and data need to be delivered efficiently and reliably over Ethernet . In summary, PoE modules provide the building blocks for powering devices via Ethernet, while PoE switches offer integrated solutions for managing multiple powered devices in a network, supporting a range of power levels and industrial-grade features.
