Extralink Passive PoE Injector 1 Port 10/100 Mbps RJ45 48 V Black

The Extralink Passive PoE Injector 1 Port 10/100 Mbps RJ45 48 V Black is a reliable device designed to transmit both power and data to a single network device over a standard Ethernet cable. Featuring a 10/100 Mbps Fast Ethernet interface, this adapter simplifies installations by combining data and 48 V DC power delivery into one cable. Built into a durable black housing, it includes LED power indicators for easy monitoring of operational status. This passive PoE injector uses two pairs of the Ethernet cable for power transmission, with positive polarity on pairs 4 and 5, and negative polarity on pairs 7 and 8.

Advantages

Using the Extralink passive PoE injector streamlines network setups by eliminating the need for separate power cords near installed hardware. It provides a stable 48 V power supply over long cable runs, reducing cable clutter and installation complexity. The unit supports standard Fast Ethernet speeds, ensuring reliable data transmission alongside power delivery. Its compact and sturdy black housing allows for discreet placement in various indoor environments while maintaining long-term durability and consistent performance.

Suitable for

• Powering IP security cameras without local power outlets
• Connecting wireless access points in remote locations
• Supplying power to VoIP desk phones over Ethernet cables
• Small-scale network installations requiring single-device power injection

This device may not be suitable for networks requiring Gigabit Ethernet speeds, as its maximum data transfer rate is limited to 10/100 Mbps. It is also not compatible with active IEEE 802.3af/at PoE devices that require automated power negotiation, as this is a passive injector operating at a fixed 48 V voltage.

Key specifications

• Fast Ethernet data transfer rate of 10/100 Mbps
• Power over Ethernet voltage of 48 V
• Two RJ-45 Ethernet ports
• LED power indicators
• Black color housing
• Dimensions of 30 mm width, 95 mm depth, and 95 mm height

How to use

To use the Extralink passive PoE injector, connect an unpowered Ethernet cable from your network switch or router to the data input port of the injector. Connect the combined data and power output port to your target network device, such as an IP camera or access point, using an Ethernet cable. Ensure that the power source matches the required 48 V specification of the device and that the power pairs correspond correctly, with positive polarity on pins 4 and 5 and negative polarity on pins 7 and 8, before switching on the power supply.

What to consider before purchase

• Verify that your network devices require a 48 V passive power supply
• Check that your network speeds do not exceed 10/100 Mbps
• Ensure compatibility with devices that accept power on pairs 4, 5, 7, and 8
• Confirm that a separate 48 V power source is available for the injector

Usage recommendations: Install the injector in a dry, well-ventilated indoor location away from direct heat sources and moisture. Always verify polarity and voltage compatibility with the connected network device before activation to prevent potential hardware damage.
