5-Pair RJ45 Passive PoE Adapter – Ethernet Power Combiner & Splitter
5-Pair RJ45 Passive PoE Adapter – Ethernet Power Combiner & Splitter
5-Pair RJ45 Passive PoE Adapter Kit – Ethernet Power Combiner & Splitter
Power and connect more devices over a single Ethernet cable with this 5-Pair RJ45 Passive PoE Adapter Kit. Designed for network installers, home-lab enthusiasts, and IT professionals, this set of 5 combiner/splitter pairs lets you transmit both data and DC power simultaneously — no active PoE switch required. Simply use a combiner at the power source end and a splitter at the device end for a clean, cable-efficient installation.
Key Features
- 5 Combiner + 5 Splitter Pairs: Enough adapters to power and connect up to 5 devices in a single kit.
- Passive PoE Technology: Uses the spare wire pairs in a standard Cat5e/Cat6 cable to carry DC voltage — no active PoE negotiation required for simple, cost-effective setups.
- Standard RJ45 Connectors: Plug-and-play compatibility with IP cameras, wireless access points, VoIP phones, and other low-voltage networked devices.
- Power & Data on One Cable: The combiner merges a DC power feed and your data line into a single Ethernet run; the splitter separates them again at the destination device.
- Durable Plastic Construction: Injection-moulded housing withstands daily handling and repeated plug-in/plug-out cycles.
- Clutter-Free Wiring: Eliminate extra power cables and power supplies at each device location — one cable does it all.
- Broad Compatibility: Works with most passive PoE-compatible IP cameras, access points, and other 12 V–48 V DC networked devices. Always verify your device's passive PoE voltage requirements before use.

Frequently Asked Questions
Q: What is a passive PoE adapter and how does this RJ45 kit work?
A: A passive PoE (Power over Ethernet) adapter transmits DC power alongside network data over unused wire pairs in a standard Ethernet cable — without requiring PoE negotiation protocols. In this kit, the combiner plugs into your router/switch and a DC power supply, merging both signals onto one Cat5e/Cat6 cable. The splitter at the far end then separates the power and data, feeding each to your device. It's a simple, cost-effective solution for powering IP cameras, access points, and similar networked equipment.
Q: Is this kit compatible with active PoE (802.3af/at) switches?
A: This is a passive PoE kit and does not perform IEEE 802.3af/at negotiation. It should not be connected directly to an active PoE switch output, as voltage mismatches can occur. It is designed for use with a separate DC power supply of the correct voltage for your end device. Always check your device's passive PoE input voltage specification before deploying.
Q: How many devices can I power with the 5-pair kit?
A: The kit includes 5 combiner and 5 splitter pairs, so you can run passive PoE to up to 5 separate devices simultaneously — perfect for multi-camera installations or distributed wireless access point deployments.
Q: What cable types are compatible with these RJ45 passive PoE adapters?
A: The adapters are compatible with standard Cat5e, Cat6, and Cat6a Ethernet cables that carry all 8 wires (4 pairs). Ensure your cable run uses a full, unshielded or shielded 8-wire cable for proper power and data transmission.
