Project Description



Data cable protection device for data technology, e.g. Ethernet network systems, Twisted Pair and control circuits. The two-level protection circuit permits transmission frequencies of up to 155 MHz. The protection devices are mounted in an aluminium housing with Sub RJ45 connector and can be mounted simply as an adapter connector.
