4.4 Connectors for external antennas and power supply
Hybrid female connector and M12 male connector
The SCALANCE W788-xPRO / W788-xRR / W74x-1xx is attached to Ethernet via a hybrid
socket on the front of the housing (position A in the figure). This port also has contacts for
the operating voltage.
CAUTION
Strain relief for the hybrid cable
Make sure that there is strain relief for the hybrid cable socket in both directions (along the
cable axis and transverse). Forces can be exerted on the socket simply from the weight of
the hybrid cable, for example when the SCALANCE W is installed high up.
Note
Protective cap for the hybrid socket
If you do not use the hybrid socket, this must be covered with a protective cap, otherwise IP
65 protection is lost. A suitable protective cap is available as an accessory (order no.
6ES7194-1JB10-0XA0). If you do not use the M12 connector, the supplied protective cap
must also be fitted to retain the IP65 degree of protection.
