SFS series: narrow width
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.
