Compact high-end network isolator

Datwyler EN-60KDS protects against all types of overvoltage

The Datwyler EN-60KDS gigabit network isolator is a compact galvanic isolator for copper-based Ethernet network connections. It suppresses potential equalisation currents and protects medical and non-medical equipment and systems as well as patients and operators from the consequences of dangerous network overvoltages which can be caused, for example, by switching operations, moisture, electrostatic discharge, differences in potential or lightning strike. It also attenuates low-frequency signal components so well that it effectively prevents ripple pickup in connected devices. It therefore has applications not only in medical technology, but also in recording studios, in measuring and monitoring technology and in the potential-free connection of remote computer systems.

The network isolator consists of a compact snap-in Keystone module and a flexible connecting cable – 20 centimetre standard, longer possible – and is suitable for device or permanent installation. Among other things it can be used in any Keystone-compatible wall outlet panel. When retrofitting existing installations its rear connecting cable acts as a simple "extension". Thanks to a new development in transmission technology the network isolator meets the performance requirements of TIA 568 Cat. 5e and ISO 11801 Class D in the permanent link and is thus designed for transmissions of up to 1 gigabit per second.

The Datwyler EN-60KDS gives a dielectric strength of 6,000 volts alternating current (VAC) at 50 hertz and 8,500 volts direct current (VDC). It meets the galvanic isolator requirements of IEC 60601-1:1988 A1:1991 and A2:1995 (2nd Edition), IEC 60601-1: 2005 (3rd Edition), IEC 60601-1-1:2000 and IEC 60601-1-2:2007. Its contacts have a particularly strong gold layer (50 μm) which ensures that perfect contact is made even after many hundreds of plugging and unplugging operations.
