Network cable Rittal DK 7030.490 RJ-45 to RJ-45, 4 m, black

The Rittal DK 7030.490 is a 4 m black network cable with standard RJ-45 connectors at both ends, designed for wired Ethernet and device-to-device connections. It is intended for linking network equipment, monitoring units and controllers that use 8P8C modular plugs. The cable provides a simple, fixed-length patch lead suitable for connecting CMC III CAN-bus units to information and power distribution systems and for general networking tasks where a reliable RJ-45 connection is required.

Advantages

The cable offers a ready-to-use, pre-terminated solution that removes the need for on-site termination or assembly. Its 4 m length balances reach and cable management for typical rack or cabinet installations. The consistent RJ-45 terminations at both ends ensure compatibility with standard Ethernet ports and many industrial monitoring interfaces. The black jacket supports discreet routing and integration into existing setups.

Suitable for (tasks / use cases)

• Connecting CMC III CAN-bus units to information and power distribution systems
• Patching switches, routers and network ports in cabinets and racks
• Linking controllers, monitoring devices and industrial network equipment with RJ-45 ports
• Temporary or semi-permanent Ethernet connections in control rooms and server areas

When it may not be suitable

This cable is a standard, pre-terminated RJ-45 patch lead and is not intended for bespoke length requirements or in-field re-termination. It does not provide specialized shielding beyond what is present in a typical RJ-45 patch cable and may not meet specific requirements for high-noise industrial environments unless a screened cable is specified.

Key specifications

• Length: 4 m
• Connector type: RJ-45 male to RJ-45 male
• Colour: Black
• Intended use: Ethernet and device-to-device connections including CAN-bus linking for monitoring systems

How to use

Insert each RJ-45 plug into the corresponding RJ-45 port on the devices to be connected, ensuring a secure latch click. Route the cable to avoid tight bends and mechanical stress; use cable ties or routing channels to maintain orderly cabling in racks or cabinets. For CAN-bus or monitoring setups, plug one end into the CMC III unit and the other into the matching information or power distribution interface as specified by the system documentation.

What to consider before purchase

• Required cable length and routing distance in your installation
• Whether a screened/shielded cable is needed for high-interference environments
• Compatibility of RJ-45 connector wiring with the devices being connected (straight-through vs crossover requirements)
• Environmental conditions such as temperature, abrasion risk and exposure to chemicals

Usage recommendations

For reliable performance, avoid tight bends and excessive tension on the cable; secure it within cabinets or along cable trays. Confirm connector pinout compatibility with your devices and consult system documentation when integrating the cable into CMC III CAN-bus and power distribution setups.
