Pre-assembled Cables - Setams SA

Application, design
The selector switches are of the same design as those of the Siemens
SINUMERIK machine control panels and can be used in
external customer control panels for the SINUMERIK 800 series.
The signal complies with the Gray code and is evaluated in the
controller according to the switch function. When the 6FC9 301-
0CC20 rapid traverse override is used, a code conversion for the
NC/PLC user interface is required in the PLC user program.
The switches are anthracite in color and are supplied with a suitable
symbol disk (adhesive) and the necessary mounting hardware.
