10BaseT/100BaseT surge protectors

25 April 2001 Circuit & System Protection

Citel offers a product line designed to protect data-processing equipment from voltage surges carried on twisted pairs by a 10 or 100 Mbps Ethernet network (10BaseT or 100BaseT). These protectors have standard RJ45 jacks for simple installation.

There are several versions:

* MJ8 2ETH: basic version for unshielded 10BaseT network (UTP). Housing with RJ45 input and output for chassis mounting. Available in shielded version (10BaseT-STP): MJ8 2ETH/S.

* MJ8 2DETH: secondary protection for internal 10BaseT networks exposed to low-energy surges only (ESD, industrial surges).

* RJ45-CAT5: RJ45 wall jack with built-in surge protector for 'Category 5' compatible 10 and 100 Mbps networks. The RJ45-CAT5 surge protector has a shielded RJ45 output jack and an LSA + IDC input terminal block. The mechanical layout allows installation in standardised ducts. All eight wires of the RJ45 connector are protected by a removable internal circuit for ease of maintenance if the protector is sacrificed.

* ZS-CAT5: electrically equivalent to the RJ45-CAT5, this version has a shielded housing and RJ45 input and output jacks for installation on a cable.

Key features are:

* 10BaseT/100BaseT network compatible.

* Nonshielded and shielded versions.

* 'Category 5' version.
