Lancom Systems AirLancer SN-LAN Gigabit Ethernet PoE Injector 1000 Mbit/s, 1.2 A, Aluminium, Blue

The Lancom Systems AirLancer SN-LAN Gigabit Ethernet PoE Injector is a compact surge arrestor adapter designed to protect LAN devices with RJ45 connectors while enabling Power over Ethernet delivery. With support for Gigabit Ethernet speeds up to 1000 Mbit/s and PoE compatibility for IEEE 802.3af and 802.3at, this aluminium-bodied unit provides basic overvoltage protection and straightforward installation in offices, retail environments and small industrial setups. The device combines a low-profile blue housing (44 × 34 × 54 mm) with RJ45 connectivity to minimize signal loss and to maintain network performance when protecting against transient voltage spikes.

Advantages

The AirLancer SN-LAN offers surge protection specifically for the LAN side, reducing the risk of damage from lightning-induced or other transient overvoltages on Ethernet lines. PoE compatibility ensures the adapter can be used in powered network deployments while keeping signal attenuation low to preserve Gigabit throughput. Its compact aluminium housing and options for mounting by plate or directly on a DIN rail simplify integration into existing racks, patch panels or equipment cabinets without occupying significant space.

Suitable for

• Protecting PoE-enabled access points and VoIP phones in office networks
• Securing Ethernet links to surveillance cameras and retail network devices
• Small industrial and branch installations where space-saving surge protection is required

How to use

Install the AirLancer SN-LAN inline on the Ethernet cable between the switch or injector and the powered device, ensuring the correct orientation of the RJ45 connectors. Secure the unit using the supplied mounting plate or attach it directly to a DIN rail as appropriate for the installation site. Verify PoE polarity and power budget of the upstream injector or switch to ensure the connected device receives sufficient current. After installation, check link status and network throughput to confirm that Gigabit performance is maintained and that the surge arrestor is functioning as intended.

Recommendations

Use the device as part of a layered protection strategy: combine LAN-side surge arrestors with proper grounding and, where appropriate, additional upstream protection for mains and network entry points. For outdoor or exposed installations, select enclosures and cabling rated for the environment and verify that the PoE power budget meets device requirements before deployment.
