DIGITUS Gigabit Ethernet PoE++-injector, 802.3bt power pins: 4/5(+),7/8(-) en 3/6(+), 1/2(-), 85W

The PoE Injector Digitus DN-95109 provides power and data over a single Ethernet cable with up to 1 Gbps bandwidth and an 85 W output, compliant with the IEEE 802.3bt (PoE++) standard. Designed as a compact midspan or endspan injector, it supports 10/100/1000 Base-T links, automatic detection of PoE devices and both PoE modes A and B. The device includes an integrated power adapter, LED status indication, and protection against excess voltage and short circuits, suitable for powering access points, IP phones, POS systems and IP cameras at distances up to 100 m.

Advantages

The DN-95109 delivers up to 85 W via four cable pairs, enabling high-power PoE++ devices to be powered and connected with a single Cat5e/Cat6 Ethernet cable. Its Gigabit data support preserves full 10/100/1000 Mbps throughput while supplying power, and the automatic PoE mode switching with device detection provides simple Plug & Play operation. Built-in short-circuit and overvoltage protection and an integrated power supply reduce installation complexity and improve reliability.

Suitable for

• Wireless access points and Wi‑Fi 6/enterprise APs requiring high power
• IP surveillance cameras and PTZ cameras with high power consumption
• VoIP/IP phones, including power-hungry conference phones
• Point-of-sale (POS) terminals and thin clients

How to use

Connect the DN-95109 to mains power using the integrated adapter. Plug a network switch or router into the data input RJ‑45 port and connect the PoE-enabled device to the PoE output RJ‑45 port. Use standard Ethernet cable (Cat5e or better) and keep the cable run within 100 m. The injector will automatically detect the connected device, select the appropriate PoE mode (A or B) and supply power and data. Monitor the LED indicator for operational status and troubleshooting.

Recommendations

Use Cat5e or Cat6 cabling for reliable Gigabit data and PoE++ power delivery, avoid exceeding 100 m cable length, and ensure the connected device supports IEEE 802.3bt to receive the full 85 W. Install the injector in a ventilated location away from moisture and excessive heat, and verify power requirements of end devices before deployment.
