7.1.3 STO (Safety) Cable Connector
The
Xenus Plus Compact
STO connector J4 is a Kycon K22X-E9S-N. It is a Dsub-9F receptacle with gold-flash
plating on the pins and #4-40 standoffs which can receive male jack-screws on the cable connector.
The mating cable connector must have crimp and poke contacts with gold flash or plating and jack-screws.
Solder-cup contacts do not have the minimum 1.24 mm spacing to meet the functional safety requirements and
must not be used.
This is an example of a cable connector that is suitable for the
Xenus Plus Compact
STO:
Housing: AMP Tyco PN 205204-4, D-Sub-9M, tin plated, crimp contacts
Contacts: AMP Tyco PN 66506-9, stamped, male, 10 micron gold, AWG 20-24
Backshell: 3M PN 3357-9209, metalized plastic with thumbscrews
Other types may be suitable as long as they have crimp and poke contacts with gold flash or plating,
jack-screws for retention, and spacings adequate for fault exclusion.
