What is the difference between Shielded and Unshielded multi conductor cable?
Well, the most obvious difference is the addition of a foil shield on the cable or an absence of that foil shield, but it goes further than that. The foil shield is used in environments where electromagnetic interference is an issue. Say for instance, that you need to run cables through an industrial or factory setting where there is high powered equipment in operation. That equipment may transmit electromagnetic frequencies that would interrupt the signal passing through the multi conductor cable. By using shielded cable, you eliminate the risk of electromagnetic interference. Each shielded wire comes with a drain wire that terminates and grounds the entire shield which in turn makes it more efficient. So why would you use unshielded multi conductor cable? In situations where there is no electromagnetic interference, the shield is not required and, in all honesty, unnecessary. The best course of action is to use the best-suited cable for the task at hand.
What benefits does each type offer?
Unshielded multi conductor cable offers the benefits of being easier to work with and being less expensive. That means that you can install this cable quicker and cheaper than shielded multi conductor cable. On the other hand, shielded multi conductor cable offers a higher level of protection, specifically from electromagnetic interference but costs a little bit more and takes a few extra steps to install. Now with that being said, they both offer some consistent benefits. Both offer high quality, durable interior conductors that are made from tinned copper. This reduces your chances of dealing with a corroded wire. Additionally, both styles carry durable yet flexible insulation as well as a durable exterior jacket. This means that these cables were designed for harsh environments. These aren’t your everyday multi conductor cables, these were made to stand up to harsh conditions for an extended period of time.

Where would you use shielded multi conductor cable?

As we said above, shielded multi conductor cable is ideal for situations where electromagnetic interference is an issue. They are built to nullify that interference and transmit your signal unimpeded. They are a solid choice for industrial or electronic facilities where a durable, yet flexible cable is needed to handle a tough environment. Not all shielded cables are flexible which is no benefit when you need to run that cable through trays or across a facility where there are turns and bends. So, you would use Pacer Group shielded multi conductor cable in situations that call for durability, flexibility, and a high level of resistance to electromagnetic interference.

Where would you use unshielded multi conductor cable?
Unshielded multi conductor cables are ideal for use in environments that require a cable to be tough and flexible while carrying multiple conductors in a protective jacket. Remember, these cables do not offer the electromagnetic interference protection that you get with the shielded cables, but not every situation calls for those. Whether you’re looking for multi conductor cables for use in a factory, industrial setting, or a boat, these cables are a solid choice for the level of toughness they offer. If they are tough enough for industrial settings, then you know they can easily handle marine applications.
What gauges are available?
Pacer Group carries both shielded and unshielded multi conductor cables in a range of gauge sizes to handle a variety of tasks. Currently, we offer both styles in 14-gauge, 16-gauge, 18-gauge, 20-gauge, and 22-gauge sizes as they are the most commonly requested. Looking for another size that isn’t listed here? Contact a Pacer Group expert today and see what else we have to offer.

How many conductors are available?
Pacer Group offers multi conductor cable with anywhere from two to twenty-five conductors. The number of conductors available is dependent on two factors. The first is whether you chose shielded or unshielded. Each style carries a different number of conductors as their intended uses are different. The second factor is the gauge size you have chosen. Basically, the rule is, the smaller the wire gauge, the more conductors available. So, where a 14-guage multi conductor cable may only offer three or four conductors, a 22-gauge multi conductor cable can carry up to twenty-five conductors.
