## Long description

The EWIMAR PTF-51-EXT/PoE/Micro v2 miniature surge protector provides transient overvoltage suppression for LAN and Ethernet lines, including PoE-powered devices. Its compact inline form factor is intended for installation at network endpoints, patch panels or near protected equipment. The device reduces the risk of damage to switches, IP cameras, wireless access points and other network devices by diverting surge energy away from sensitive data and power lines while maintaining signal integrity for Ethernet communication.
Advantages
The miniature design of the EWIMAR PTF-51-EXT/PoE/Micro v2 allows integration in confined spaces without significant changes to cable routing. It is compatible with Ethernet and PoE systems and is designed to limit transient overvoltages on both data pairs and power conductors. Installation at points of entry or in-line at endpoints offers a practical way to protect individual devices without modifying the overall network topology.
Suitable for
Protection of IP cameras and other PoE-powered surveillance equipment
Inline protection for wireless access points and network switches
Surge mitigation at patch panels, network endpoints or small distribution points
Commercial and industrial Ethernet installations requiring point-of-use protection
Key specifications
Function: transient overvoltage suppression for LAN/Ethernet with PoE support
Form factor: compact, inline/micro design for endpoint or panel mounting
Application: suitable for data pairs and PoE power conductors in Ethernet cables
Installation location: designed for placement at device endpoints, patch panels or network entry points
How to use
Install the EWIMAR PTF-51-EXT/PoE/Micro v2 inline on the Ethernet cable feeding the device to be protected. Connect the incoming network cable to the protector’s input and route the protected output to the device. Ensure connections are secure and maintain correct pair wiring to preserve Ethernet signal continuity and PoE functionality. Mount the device in a dry, accessible location near the protected equipment or at a patch panel position, following standard safety practices for working with live network equipment.
Usage recommendations
For optimal protection, position the surge protector as close as possible to the equipment being protected and use one protector per device or per endpoint. Regularly inspect connectors and cable integrity; if a protector shows signs of damage or degraded performance, replace it to maintain protective function. Consider coordinated protection at service entrances and intermediate distribution points for larger or more exposed installations.
