Total safety switching
solutions from Omron
Many of the new features in these switches are unique.
Make-before-break contacts, for example, provide enough
time for vital process information to be saved before the
system is shut down. More contacts have been added 
to the switches so that one is available to provide 
feedback data to the control system. Gold-clad contacts
have been included for switching micro-loads and 
higher current more reliably. And all switches are tested 
to guarantee at least 1 million operations. No matter how
safety-critical the requirement, Omron’s D4N series has
an excellent product solution for your application!
