3 Shielded Cable Options to Block EMI

The shields on these cables are designed to surpass electronic interferences, which will promote smooth electronic conductance. This will help the cables perform better even when they are close to other working wires and cables. A lack of interference between wires is especially important when the wires are in close proximity to each other. Even because each wire has a specific job to do the interference between the wires can cause problems.
PVC Shielded Cables
The cables with a PVC shield are the most basic and inexpensive cables you can purchase. These cables have either an aluminum foil shield or tinned copper braid shield. This depends on the level of EMI protection that is needed. The tinned copper shield also gives the cable excellent corrosion resistance. These PVC shielded cables have been rated to be able to handle temperatures ranging from as low as -20C and up to 80C. They are however only used indoors because the outside environment would be too tough for these cables.
STJ Cables
STJ stands for shielded tape jacket cable. These always have a tinned copper braided shield. The shield is placed between the lead wires and the jacket to limit the amount of heat hitting the insulation of the wires. These cables are also rated for 200C temperatures instead of 105C. The inner conductors of these cables are Type E wires so they also have a high temperature rating. Plus the braided tinned copper shield has up to 90% coverage on the wire.
Robotic Flexible Cables
The robotic flexible cables from Olflex come with a tinned copper braid shield. These are to block EMI from cables next to each other in a cable track. Large equipment and robots have cables running next to each other and need to limit the circumference of the magnetic field to block interference. The Olflex flexible robotics cables also have two other insulation jackets to maintain proper conductance. The jackets make sure that the cords are not only good for electronic purposes with low interference but also they have good oil resistance.
The shielding on cables is very important. Preventing electronic interference can help boost the performance of the wire or cable. They also give added protection against other things such as corrosion. Each different kind of shielding however will help the wire or cable withstand different temperature ranges. Make sure you look into the level of protection you need before purchasing a shielded cable.
