Power over Ethernet (PoE) is a technology for sending both electrical power and data over a single Ethernet cable. PoE has been developed to simplify the installation of network devices such as wireless access points, IP cameras, VoIP telephones, and other equipment, as it eliminates the need for putting many cords and cables around the building. The PD67124AM is a midspan PoE injector that is designed to convert standard Ethernet signals into PoE and provide up to 24 watts of power to the connected device. In this article, we will explore the applications and working principle of the PD67124AM.

Applications of the PD67124AM

The PD67124AM has been developed specifically for midspan applications, meaning that it provides power to devices that don\'t support the IEEE 802.3af-2003 Power over Ethernet standard. It is compatible with 24 and 48V PoE Powered Devices (PDs) that require up to 24W of power, and can provide both data and power simultaneously over a single Ethernet cable. Some common applications for the PD67124AM include powering VoIP phones, network cameras, and wireless access points.

Working Principle of the PD67124AM

The PD67124AM utilizes the IEEE 802.3af-2003 PoE standard to send power over Ethernet cables. This standard works by sending electric current over the Ethernet\'s unused pins of the RJ45 connector, which is then transformed by the receiving device into direct current. The PD67124AM is capable of providing up to 24 watts of power, and can work over a range of cables, including Cat5, Cat5e, and Cat6 cables.

When a PD is connected to the PD67124AM, it will detect the PoE signature on the Ethernet cable and detect the amount of power required. If the required power is equal to or below the PoE injector\'s specification, then the device will be powered. The PoE injector can be controlled remotely using an on/off switch, which can be used to turn the power off and on as desired. This is useful for resetting a device remotely or for troubleshooting.

Conclusion

The PD67124AM is a midspan PoE injector that can be used to power devices that don\'t support the IEEE 802.3af-2003 Power over Ethernet standard. It has a wide range of applications, from powering VoIP phones and network cameras to wireless access points. The PD67124AM works by sending electrical power over Ethernet cables, utilizing the IEEE 802.3af-2003 PoE standard. It can also be controlled remotely, using an on/off switch, making it an ideal choice for powering PoE devices.
