Belden DataTuff Cat 5e 600V AWM-rated cable.
The drives that control processes and the switch gear that handles critical power functions must perform flawlessly and at peak efficiency. Current control and communications systems are very reliable, but with the advance of Ethernet technology now reaching motor control centres and switch gear, the cabling component must be especially reliable and robust.
Ethernet is finding increased use in industrial environments since it is a standards-based technology that utilises a single cabling platform with Ethernet connectivity and IP addressing. This convergence of open, standards-based communications provides secure, seamless interoperability between the corporate office and the plant, plus it enables Internet connectivity anytime and anywhere. Industrial Ethernet communications are also faster than current network protocol technologies and they provide greater bandwidth.
The advance of Ethernet has prompted an increased use of intelligent devices equipped with Ethernet ports. As these devices are often in close proximity to noise-producing machinery, an electromagnetic interference problem might occur that could prove detrimental to signal integrity. In MCCs, drives could produce enough EMI to interfere with many traditional Ethernet cables. Moreover, the need to monitor and control these devices will demand that the cable enter the MCC. As a result, these applications require an Ethernet cable with excellent noise immunity, as well as the ability to run on or near listed devices.
Benefits of using Belden DataTuff category 5e 600V AWM-rated cables
Belden provides two Industrial Ethernet Category 5e cables designed specifically for superior electrical performance and outstanding noise immunity. The Belden DataTuff 4-pair shielded cables carry a 600V AWM rating which makes them approved for use in listed MCCs and switch gear, and they feature Belden’s patented Bonded-Pair technology. While these cables have the design and certifications that make them ideal for MCC and switch gear applications, they can also be used for more traditional Ethernet applications. They are not, however, intended for 600 V power delivery.
Belden’s bonded-pair technology
Belden bonded-pair cables have the conductor insulation of the cable pairs affixed along the longitudinal axes to ensure that no performance robbing gaps can occur between the conductor pairs. Since no gaps can occur, and the conductor-to-conductor spacing is always uniform, the cable offers excellent electrical performance – even when it is subjected to the rigors of the factory floor environment.
Belden DataTuff Category 5e Industrial Ethernet cables feature 24 AWG Bonded-Pair solid bare copper conductors, polyolefin insulation, 24 AWG stranded tinned copper drain wires and industrial-grade oil- and sunlight-resistant PVC jackets. The shielded design provides assured performance in highly concentrated EMI/RFI environments. Belden’s Beldfoil shield, with its aluminum/polyester foil, offers 100% protection against EMI/RFI. When the shield is used in combination with the 70% braid shield, the cable offers enhanced structural integrity and a lower DC resistance.
