## Summary description

PoE injector Raspberry rb-poehead3 provides Power over Ethernet delivery compatible with the 802.3af standard. Designed to inject power into an Ethernet cable for devices that support PoE, it enables network and power over a single cable, simplifying installation of compatible equipment such as Raspberry Pi PoE HATs and other low-power network devices. Useful for mounting devices in locations without nearby power outlets and reducing cable clutter.

## Long description

PoE injector Raspberry rb-poehead3 802.3af compatible provides Power over Ethernet delivery compliant with the 802.3af standard. It is designed to inject DC power into an Ethernet cable so that compatible devices can receive data and power over a single network connection. The unit is intended for use with low-power network equipment such as Raspberry Pi PoE HATs and similar devices, enabling installation where separate power outlets are not convenient and helping to reduce cable clutter.
Advantages
This PoE injector follows the 802.3af power specification, allowing straightforward integration with devices that expect standard PoE input. By combining power and network on one cable it reduces the need for additional power adapters and simplifies mounting of networked devices in ceilings, on walls, or in remote locations. The compact design is suitable for discreet installations and for use in small network setups where a separate power source is impractical.
Suitable for
 Supplying power to a Raspberry Pi equipped with a compatible PoE HAT
 Small network cameras and low-power IoT devices that accept 802.3af
 Deployments where a single cable for network and power reduces installation complexity
 Locations without nearby AC outlets such as ceilings, poles, or cabinets
Key specifications
 PoE standard compatibility: 802.3af (PoE)
 Power delivery type: DC injection into Ethernet cable
 Intended load class: low-power network devices and PoE HATs
 Network interface: standard Ethernet port for data and power pass-through
 Form factor: compact inline injector suitable for discreet mounting
How to use
Connect the injector to a powered DC source following the device's power input requirements, then connect the network switch or router to the injector's data input port. Plug the Ethernet cable from the injector's output port to the PoE-capable device such as a Raspberry Pi with a compatible PoE HAT. Ensure connectors are fully seated and that the target device supports 802.3af power negotiation before applying power. Follow any device-specific instructions for safe operation and mounting.
Usage recommendations
Install the injector in a dry, ventilated location and use appropriate Ethernet cabling (Cat5e or higher) for stable power and data transmission. Verify the total power draw of connected devices remains within the 802.3af limits. When mounting in restricted spaces, allow clearance for connector access and consider securing cables to prevent strain on ports.
