sensors - safety devices - muting module
If OSSDs are to be used without this handshake capability that is, non-XXX Safety devices), interposing safety relays or interfacing modules must be used to provide hard contacts and be wired as shown in Figure 20.
what are hard contacts? what's the difference with relay contacts?
(OSSD = output signal switching device - however I think it refers to outputs where such devices are connected)

My guess
I would assume here that the difference is between, say, optoelectronic contacts and real metal-to-metal relay contacts.
The optoelectonic contacts have a photodiode that emits light when current passes through it. This light is sensed by a phototransistor that conducts when it senses light. While these devices are encased in the same block of plastic there is NO physical, electrical connection. So in my opinion, this is NOT a "hard contact" in your sense.
Relays, on the other hand, have metal that contacts metal to send the electrical current on its way. This, then, would be your hard contact.
My thoughts from the USA.

physical contacts
my take, but your text sounds kind of odd, maybe a backtranslation?

: Yes, though the text sounds fine to me, not odd at all, just jargon! Takes a techy to know one :-)

: Isn't a 'nonswitched contact' called a "wire" in English?

: No, sorry, this is exactly the opposite of what it means in this context!
