OKUIC

OK series plug-in relays are designed and built with materials and solutions that impart excellent characteristics of endurance and ruggedness; suitable for use in harsh operating environments and when subject to strong thermal shocks. Above all, thanks to their elevated shock and vibration resistance, these relays are suitable for use on rolling stock and in seismic environments.

The excellent electrical and mechanical performance of these relays allows them to be used in the most demanding sectors, such as control and signalling functions in rail transport or in applications with continuous production processes.

Magnetic arc blow-out, ample contact clearance, exceptional efficiency in breaking DC loads and pulsed 5 kV insulation between open contacts.

Patented operating mechanism: mechanical life expectancy > 100,000,000 operations.

The contacts are mounted on individual and independent blades, deigned to assure unparalleled pressure values on the make and break contacts, in the region of 0.8…1N. Sliding and self-cleaning contact.
