Roboflex is made in 2 through 24AWG with varying conductor counts.  The Mueller Group stocks many of these sizes in Chicago.  Contact us to inquire about the product line or request a quote today.


Automation Integration

As in all aspects of business, end users & machine builders need to maintain a high level of efficiency in order to be competitive.  Siemens Drive Technologies is introducing a new drive system that will integrate products & services already being used.  The integrated system will allow for a simplified process reducing waste, time & resources.  The system is first being applied to the oil & gas, mining, & cement industries.

The Mueller Group stocks the full line of cables used in Siemens Motors.  Whether for motor or feedback, we can supply cost effective equals made to the same specifications as Siemens 6FX products.  Contact The Mueller Group for more information.

Featured Product: Multiflex-P

MULTIFLEX-P is a polyurethane, high flex, heavy-duty, oil-resistant, halogen-free, continuous flex multi-conductor drag chain cable.  It is designed for use in the machine tool industry, robotics, machine production and drag chains where high flexibility is essential. It is suitable for use in permanent flexing and stationary applications under high mechanical stress with free movements in dry, damp or wet areas.  These halogen-free cables offer optimum service life and an expanded temperature range commonly found in movable automated machine parts, cable tracks and multi-shift operations.  It is best used for applications that require extreme bending stress and smallest bending radius possible with long travel distances.

The rugged PUR jacket offers high abrasion, tear resistance and adhesion-free qualities along with good chemical resistance to coolants and mineral oils.  Outdoor installation is permitted due to the weather, ozone and UV-resistant outer jacket.

Multiflex-P  is The Mueller Group’s 240 Series. We stock various constructions 16 through 20 AWG.  Download the spec here and contact The Mueller Group to request a quote.

Being Green in Wire & Cable

As we’ve talked about before, choosing the insulation and jacket material is a crucial part of the cable selection process.  But as cables are being improved, there are more options and considerations to be made.

In a recent Assembly Magazine article, cable insulation was the topic, with a ‘Green’ focus.  Cable insulation not only needs to be able to stand up to conductors of higher voltage, but also needs to be compliant with new standards and expectations of being environmentally friendly during and especially at the end of it’s life.  While many applications require low smoke, halogen free insulation, it is more difficult to recycle and dispose of.  On the other hand, the common jacket material, PVC, is very easy to recycle.  However, it contains halogens and releases hazardous chemicals when burned.  There are now several companies that are developing new materials that are safe while in use and easily recycled at the end of the cable life.

Over the next few years, the industry will see an increase in lighter, more efficient, and ‘Greener’ materials.  As this becomes more and more of a standard, look to The Mueller Group to be your provider of environmentally friendly European Wire & Cable.  In the meantime, we are happy to provide you with the same quality products and service you have come to expect from us.

PVC vs. Polyurethane Jackets

When reviewing the specs on any given cable we hear about the color, cores, and voltage, but we also hear about the outer jacket.  The most common types of jackets are polyvinyl chloride (PVC) and polyurethane (PUR).

The visible difference between the two materials is that PVC has a more polished look while Polyurethane is more matte.

Both materials are flexible, have good electrical properties, and are available with RoHS, VDE, CE, and other various certifications.  The most noticeable difference at first glance in comparing these two materials is cost.  But what are the actual differences?  PVC and PUR hold different properties that make them suitable for different applications.  PVC is used when a resistance to fire and ozone is of higher importance.  It does not rate as well on abrasion or weather resistance and does not have environmental benefits that relate to low smoke and halogen free.  Polyurethane, on the other hand, rates extremely well when it comes to high flexibility, tear & abrasion resistance and overall durability.  Its greatest downfall is its lower flame resistance and higher cost.

When selecting a jacket type on a cable, it is important to review the application in which it will be used and make the decision based on what the requirements are.  The staff at The Mueller Group can help decide what type of jacket for a particular cable is best for your application and offer a product from our vast inventory.
