Notes
The sensors permit reliable
position sensing. It is then
possible to switch between
different safety functions.
Switches are mechanically
connected, are protected against
manipulation and securely
mounted.
Sample application:
In two-hand operation, the
cylinder advances to an
uncritical position where
the position of the hands no
longer needs to be blocked.
The two-hand switches can now
be released.
Reversing the safety function
Part no.
