6mm-wide safety relays are the ‘world’s thinnest’

15 April, 2015

At the Hannover Fair, Phoenix Contact has unveiled a 6mm-wide safety relay which, it claims, is the world’s narrowest and could result in space savings of up to 70%. The new PSRmini relays are small enough to be integrated directly in devices such as motor starters and are claimed to deliver a similar performance to larger safety relays.

The relays’ compact shape has been achieved by using a newly developed technology based on a narrow, high-performance elementary relay, which as well as being small, has a low current consumption, cutting energy use by up to 20%. To ensure safety, the relays use force-guided contacts and comply with EN 50205.

The elementary relay has both normally open and normally closed contacts and is therefore suitable for use in fine-scale safety concepts with one or more enable contacts. They can switch loads up to 6A and are said to be particularly suitable for use by machine-builders and in the process sector

The safety relays can be used in potentially explosive areas, thus simplifying the design of distributed installations. Termination carriers allow the use of system cabling for fast, error-free start-ups and connections in the field.

The complete PSRmini safety relay range consists of 28 products in 6mm and 12mm versions. To ensure production accuracy, Phoenix is manufacturing the relay and all of its parts in-house.
