Safety relays, i.e. relays with mechanically forcibly guided contacts per DIN EN 61810-3, are used wherever people, machines and valuable goods must be protected from injury and damage. One such relay comprises at least one NC contact set and one NO contact set and is constructed such that the NC set and the NO set can never be closed at the same time. For example, if a NO contact fails when trying to open, the associated NC contact cannot close when the power supply is switched off. This behaviour enables simple diagnostics and fault detection when monitoring the forcibly guided feedback contacts....

Relays with mechanically forcibly guided contacts are used in safety relay modules or controllers amongst other things. The simplicity in the use of safety relays makes them the ideal component for detecting faults due to the forced driving of NC and NO contacts without the need for complex circuitry. In these safety relevant applications, particular attention is paid to the compact form alongside the high degree of switching security. At just 10.3 mm height, the extremely flat relay family OA 5642, OA 5643 and OA 5644 with 2, 3 takes account of the desire for components to be ever smaller and...
