Your Smart Helper for Power Supply in the Network
No more cable clutter and endless searching for the next power outlet! Our Passive PoE Injector is the clever solution to efficiently power your Network devices like IP Cameras or WiFi Access Points. Imagine mounting a camera under the roof or an access point on the ceiling – with this PoE Fast Ethernet Adapter, you only need a single Ethernet cable that supplies both data and power. This not only saves time and effort during installation but also costs for additional power cables and power supplies.
Flexible, Simple, Efficient: Your Advantages at a Glance
This PoE Injector shines with its versatility. It supports a wide voltage range from 12V to 48V via its standardized DC jack (5.5 x 2.1 mm). This means you can combine it with almost any suitable power supply you might already own. Particularly practical: The applied voltage is passed on 1:1 to your end device. An integrated LED shows you at a glance whether the injector is powered – troubleshooting has never been easier! It's perfect for DIY smart home projects with Raspberry Pis or ESP32 sensors, temporary field installations where you might even want to use a power bank, or to give older Network devices without the 802.3af standard a second youth. This way, you extend the lifespan of your hardware and save on installation costs at the same time.
Important Notes for Optimal Use
As a Passive PoE Injector, this device offers maximum simplicity, but there are two important points to note: Firstly, it is a PoE without 802.3af Standard. This means there is no voltage negotiation with the end device. You must ensure that the voltage you supply exactly matches the required voltage of your end device to avoid damage. Secondly, this injector is designed for Fast Ethernet (10/100 Mbps). It is not compatible with Gigabit Ethernet. The wires used for power transmission are needed for data in Gigabit Ethernet. Connecting to a Gigabit device on the 'Data and Power Out' port can lead to damage. Therefore, always pay attention to the correct specifications of your devices.
Frequently Asked Questions about your Passive PoE Injector
What is a passive PoE injector?
A passive PoE injector feeds power into an Ethernet cable to supply network devices without a separate power outlet. Unlike active injectors, it does not negotiate the voltage but directly passes on the applied input voltage.
What is a passive PoE adapter used for?
It is used to power network devices in locations without a power outlet by combining data and power supply over a single Ethernet cable.
What voltage can a passive PoE injector handle?
This injector processes variable input voltages from 12V to 48V. The input voltage is passed on 1:1 to the connected device.
Is this PoE injector compatible with Gigabit Ethernet?
No, it only supports Fast Ethernet (10/100 Mbps) and is not suitable for Gigabit Ethernet. Connecting to a Gigabit device can damage it.
Can I operate this passive PoE injector with a power bank power supply?
Yes, this is theoretically possible if the power bank provides a suitable DC output (5.5 x 2.1 mm) and the correct voltage for your end device.
Which pin assignment does this passive PoE injector use for power supply?
It uses pins 4/5 for Plus (+) and 7/8 for Minus (-). Data transmission occurs over pins 1/2 and 3/6.

Frequently Asked Questions (FAQ)
What is a passive PoE Injector?
A passive PoE injector is a device that injects power into an Ethernet cable to supply power to network devices such as IP Cameras or Access Points, without requiring a separate power outlet at the device. Unlike active PoE injectors (802.3af/at), it does not negotiate the voltage but directly passes on the applied input voltage.
What is a passive PoE adapter used for?
A passive PoE adapter is used to power network devices in locations where no power outlet is available, such as in attics, on ceilings, or on exterior walls. It combines the data signal and power supply over a single Ethernet cable.
What voltage can a passive PoE injector handle?
This passive PoE injector can handle variable input voltages from 12V to 48V, depending on the power supply used. The input voltage is passed on 1:1 to the connected device.
Is this PoE injector compatible with Gigabit Ethernet?
No, this passive PoE injector only supports Fast Ethernet (10/100 Mbps) and is not compatible with Gigabit Ethernet. Connecting it to a Gigabit Ethernet device on the "Data and Power Out" port can damage the device, as the pins used for power transmission in Fast Ethernet are used for data in Gigabit Ethernet.
Can I operate this passive PoE injector with a power bank power supply?
Yes, theoretically this is possible, as long as the power bank has a suitable DC output (hollow plug 5.5 x 2.1 mm) and the output voltage of the power bank matches the required voltage of the end device (e.g., 12V, 24V). It is important to check the voltage carefully, as the passive injector does not negotiate voltage.
Which pin assignment does this passive PoE injector use for power supply?
This passive PoE injector uses pins 4/5 for positive (+) and 7/8 for negative (-) for power transmission. Data transmission occurs via pins 1/2 and 3/6.
