LAN Port Protector Adapter with Overtension Auto release (OTAR), Class D Gigabit Ethernet Performance The LAN Port Protector network adapter does not replace a network isolator and does not provide surge protection between the network and the connected end device. If the tensile forces on the cable exceed a defined limit, the locking mechanism is released automatically. The Ethernet socket of the end device is mechanically protected by our new LAN Port Protector (OTAR). https://elecena.pl/product/17871752/a10308-lan-port-protector-network-adapter-with-otar 2021-04-24 https://elecena.pl/product/17871752/a10308-lan-port-protector-network-adapter-with-otar 2023-04-23
