The multistage technique has proven to be the most cost effective and reliable method for protecting sensitive electronic equipment. Employing state-ofthe-art avalanche junction diode technology, these devices provide superior performance for video, Ethernet, Token Ring or other LAN interface systems. They are in-line modules with easy interconnecting terminals. A completely enclosed aluminum housing provides EMC shielding to meet industry standard requirements. The enclosure has two female BNC type connections for easy installation. The case is grounded for those installations that require external ground connections.
