Industrial Ethernet FastConnect (IE FC) is a fast assembly sys-

tem with insulation displacement for easy assembly and wiring 

of 4-core and 8-core IE FC cables. Using the FC Stripping Tool it 

is possible to remove the outer casing and the woven shield of 

the IE FC cable accurately in a single step. The cable prepared 

in this manner is subsequently assembled on the contacts of the 

connection element.

■

The connection elements which can be used depend on 

whether the transmission rate is 10/100 Mbit/s or 1000 Mbit/s:
• IE FC RJ45 Plug 90/180 (10/100 Mbit/s) in association with 

4-core (2 x 2) IE FC cables

• IE FC Outlet RJ45 (10/100 Mbit/s) in association with 4-core 

(2 x 2) IE FC cables

• IE FC RJ45 Modular Outlet (10/100/1000 Mbit/s) with 8-core 

(4 x 2) IE FC cables

The following table provides an overview of the available 

switches, the transmission rates they support, and the IE FC 

standard cables and IE FC connection elements which can be 

used. In addition to the IE FC standard cables, Catalog IK PI of-

fers further IE FC cables with special properties.

IE FC RJ45 Plugs
The IE FC RJ45 Plugs are the ideal solution for communication 

links with a transmission rate up to 100 Mbit/s. They permit sim-

ple, fast and direct assembly of the 4-core (2 x 2) twisted pair 

(TP) FastConnect installation cables in the field (without patch 

technology) up to a cable length of 100 m. Since the IE FC RJ45 

Plugs have no parts which can be lost, assembly is also possible 

under difficult conditions.

IE FC Outlet RJ45 and IE FC RJ45 Modular Outlet

Alternatives for conversion from RJ45 to the insulation displace-

ment system are the 
• IE FC Outlet RJ45 for 4-core TP (2 x 2) IE FC cables and trans-

mission rates up to 100 Mbit/s and 

• IE FC RJ45 Modular Outlet for 8-core TP (4 x 2) IE FC cables 

and transmission rates up to 1000 Mbit/s. 

The latter has the advantage that the existing wiring can still be 

used if the communication is converted from 100 Mbit/s to 

1000 Mbit/s. It is only necessary to replace the 2FE insert by one 

of type 1GE. In contrast to the plugs, an RJ45 patch cable 

(TP Cord) is additionally required for each outlet which connects 

this to the network components or data terminal. 
Detailed information on the FastConnect Outlets and the avail-

able TP Cords can be found in Catalog IK PI, Section "Industrial 

Ethernet", and in the A&D Mall, or in CA 01 under "Communica-

tion/networks / SIMATIC NET communication systems".
Further information on network structures is provided in the man-

ual for TP and fiber-optic networks.
