Transmission range
The maximum transmission range (segment length) is 100 m.
Connectors
The connectors used are 8-pin RJ-45 jacks with securing collars. The securing collar in
conjunction with the cover ensures a flush fit and the locking mechanism with the
PROFINET-compliant male connectors IE FC RJ-45 Plug 180 and IE FC_RJ-45 Plug 145
provides a rugged node attachment suitable for an industrial environment that provides strain
and bending relief for the RJ-45 jack.
