Electromechanical and semiconductor relays

SFS series: narrow width

Thanks to a slim design, SFS devices require little PCB space. A broad line-up of contact types including 2a2b, 3a1b, 3a3b, 4a2b and 5a1b is offered.

Slim in design, safe for man and machine

Thanks to its forcibly guided contact structure, the SFS relay ensures that subsequent operations will be shut down and/or set into a safe state in case of the SFS relay suffering an overload – or from any other circuit abnormalities. This effectively prevents technical defects and thus ensures the safety of man and machine. Additional plus: The relay’s slim design only takes little mounting space on the PCB and thereby suits the requirements of modern and minimalistic product designs.
