PVC, PUR & TPE
CABLE JACKET INSULATION
What are the differences between the three?
So what are the differences between PVC, PUR and TPE instrumentation cable jacket insulations? You've probably heard about all three. Each has different strengths and can offer unique protection in guarding cables against environmental factors that cause damage, wear and tear which, in turn, adds longevity to your instrumentation cables and can eliminate a lot of unplanned machine downtime.
Sow how do you choose the best instrumentation cable? That depends on the environment of your production floor. Does what you manufacture involve high temperatures or flame? What about extreme cold? Are chemicals used to process your product? Or does your machinery require frequent washdowns during or after shifts?
Read on to discover more about PVC, PUR, TPE and which is the best cable jacket insulation for your specific application.
Polyvinyl chloride is a great choice for general purpose use which allows us to give a great price point. Because of its high moisture resistance, PVC is great for use in wet or humid conditions.
Polyurethane offers good resistance against abrasion, oil and ozone. PUR is halogen free, meaning it does not contain chlorine, iodine, flourine, bromine or astatine.
Thermoplastic elastomer is flexible, recyclable and has the ability to withstand chemicals and endure harsh temperatures. TPE is resistant to aging in sunlight, UV and ozone. It also has a high flex rating, typically 10 million.
* This insulation is manufactured and applied to all 18 AWG instrumentation cables in house at Mueller Electric which gives a lower price point than PUR!
Here is a handy chart below that summarizes the performance of PVC, PUR and TPE when using different applications.

Topics: Factory Automation Cables
Recent times have forced various industries to move towards automating everything possible in order to provide a consistent output and improve quality. This allows manufacturers and builders of all types to run at full production. With the availability of the workforce uncertain, demand for robots is skyrocketing.
Robots are now being utilized in expanded capacities. Manufacturers, already heavy in factory automation, are now using robots with machine vision. Machine vision systems can locate the position and orientation of a part, compare it to a specific tolerance and ensure it is at the correct angle to verify proper assembly. Machine vision guidance achieves greater speed and accuracy than manual positioning in such tasks as arranging parts on or off pallets, conveyor belts, finding and aligning parts for assembly, placing parts on a work area, or removing parts from bins.
More and more manufacturers are also using robots to pick and pack orders in response to COVID. Automated shipping is now being heavily implemented as a way to cut down on the amount of times packages are touched and reduces the need for social distancing.
Another way robots are being utilized is having them expedite building construction. This system features a robotic arm and custom end effector which is driven by advance computer vision sensing technology, allowing the automation of certain construction site tasks. Additionally, robots can access hard-to-reach underground systems that may be too dangerous or inaccessible for humans. How it works is the robots' ultrasound and acoustic sensors enable the robot to detect cracks, blockages an the overall condition of the pipes, while the use of infrared sensors and magnetic field sensors enable the robot to navigate through the pipes themselves. Once the data is collected on the condition of the pipes the data is sent to water utilities. This technology helps to reduce costs associated with the excavation necessary to maintain or repair pipes. This, in turn, could help municipalities to avoid road closures.
This is truly exciting technology and we are only touching the tip of the iceberg. Robots are in strong demand as is all factory automation. Because of this the supply chain for parts to build and install the robots and all factory automation has been severely challenged. Lead times are being stretched out and suppliers, even those who has been strong on delivery in the past, are running thin and witnessing long lead times.

CODING FOR TODAY AND TOMORROW
Have you wondered about the different coding types for instrumentation cables and what they mean?
M12 cables have come in a variety of coding options and each code is used for a specific application. Simply put, M12 codes are designed to keep cables mating with the correct connections to ensure that, for example, an AC power cable is not being hooked up with an Ethernet cable.
From the outside, connector housings look the same but when you consider the internal configurations of the M12 connector, things are quite diverse. Most users of M12 cables are familiar with codes A through D and possibly X. There are more codes in addition to these and some have been designed to replace existing codes. Below are keyways commonly used today. Below that are keyways less well known that may become more prominent in the future.
How do you know which code is right for you? Feel free to look through our assortment of
instrumentation cables and their related coding to see which best fits the application needed. If you still have questions or don’t see what you’re looking for, feel free to contact me at 800.955.2629 to discuss what you want to accomplish and I can assist you in finding the right cables. On the rare chance you don’t see what you’re looking for, Mueller Electric can always create custom cables based on your company’s specific needs.
A-coded connectors are the most common type of keyways and are used with sensors, actuators, attenuators, motors and other devices. B-coded connectors are most often used in network cables for fieldbus connections. C-coded connectors are used mainly with AC sensors and have a dual keyway for security, used to make sure no other cable is accidentally used in place of a C-coded cable. D-coded connectors are generally used for Ethernet and can transfer data up to 100 Mb. X-coded connectors are becoming more popular due to their ability to transfer large amounts of data, up to 1 Gb, at high speeds.
Protective Utility Grounding assemblies are used on de-energized lines when the crews are performing maintenance or are making changes to the grid. The grounding assemblies are to ensure any spikes in electricity are rerouted to the ground and out of harms way.
In most cases there are three lines or more which will need to be grounded. To do this effectively the grounding cables will need to be connected to the lines as illustrated in the picture.
In this case, five grounding assemblies are required to make the ground connection complete and safe. The final, or lowest assembly, is attached to the grounding rod which is screwed into the ground.
An aluminum connecting rod is available to attach the clamps if necessary. This keeps the clamps in close proximity to each other when placement is important.

Paint line managers of electrostatic paint lines are often tasked to provide plastic substrates with an evenly distributed bright and shiny paint coating and with keeping the painting environment safe.
That’s easy, right? Most people think that all they have to do is to make sure the substrate is grounded.
Yes, that is true, but how do you really know if the ground in place provides a consistent low level of resistance?
One way to check the resistance of the plastic substrate is with a multi-meter (after the conductive costing is applied). This will provide an accurate measurement as long as both probes are placed as needed. The problem is that you need 3 hands to hold the two probes plus the meter, while you touch the probes to places that are often far apart. Additionally, the probes are pointed, so caution must be taken to not scratch or damage the plastic substrate which could remove the conductive primer. The process of using a multi-meter to take a consistent reading across the entire plastic substrate can be very cumbersome and time consuming while the line is in full operation.
A much easier and more efficient way to take a measurement of resistance is to use the Ground Analyzer from Mueller Electric. This is a hand- held device that provides the tools to take a quick and easy measurement of the ground effectiveness across the plastic substrate. The Ground Analyzer will take a reading but will also provide a quick go-no go indicator which will allow the paint line manager to know if the substrate is grounded throughout and is ready for base coating. Every paint manager has their own unique requirements for appropriate grounding levels. For some it may be 500Ωs while others may go at 1MΩ or higher. The Ground Analyzer allows for a threshold to be set at various preset levels (one setting is available for user input) and the reading taken will provide a green indicator if the resistance measurement is below the threshold. If the reading is above the threshold the indicator will turn red alerting the operator to the fact that a better ground is needed. For a better understanding of how the Ground Analyzer works you can watch the video or see the PDF here.

Everyone wants a safe work environment. One of the workplace hazards are explosions and fires due to static discharge, but these can be mitigated by grounding equipment. Proper grounding is the only way to ensure true static protection if you are in any environment where the potential for static discharge exists.
Many places ground with heavy duty cast clips, solid copper clips and clamps of all shapes and sizes connected to a wire and attached to drums and pipes throughout a storeroom, plant floor or pumping stations. These are referred to as grounding assemblies or “straps.”
These areas may or may not be perfectly grounded. Even though they may look grounded, it’s hard to tell if it’s done properly. An improper ground could mean safety hazards that can lead to fire or explosions.
First and foremost, it must be determined that access to a fully grounded grounding pin or buss bar is readily available. This will be necessary for a solid true ground and will act as the backbone of the grounding system. Keep in mind, however, that the grounding pin and buss bar must be kept clean so solid metal-to-metal connections are made.
The next step in ensuring that something is properly grounded is to make sure the correct connection device is utilized.
Many times a C-clamp or center spring clip will be used for this connection. This would certainly result in a good connection as the C-clamp can bite into the metal pin or buss bar and the clamp pressure on the center spring clamp is strong enough to drive the teeth into the metal pin or bar. It’s important that the clamp or clip is able to pierce any paint that might be on the surface. The connections on the grounding pin and buss bar must be solid tight connections as maintaining continual connectivity is critical for the integrity of the entire grounding system.
The type of cabling used from connection to connection (grounding pin / buss bar to clamp or clip) will depend on the environment being grounded. If the environment is clean such as a paint mixing room, uninsulated stainless steel wire rope or braided copper can be utilized. In other applications where the environment may contain more contaminants, an insulated wire may and should be considered such as THHN (oil and gas resistant).
Now that the connection to the ground source and wire are complete, focus can be placed on the connection to the can, drum, or tank. This connection can be made with a cast clamp with points, C-clamp containing a point or center spring clip with strong clamp pressure and teeth. The type of connection depends on the type of surface in which it is being attached. If the surface is clean and free of dirt and paint, a center spring clip can work fine. The size of the clip will be determined by the size or thickness of the object being grounded. If the container is dirty or painted the connection will need to be made with a connector which will break through those layers to make a solid metal-to-metal connection. Cast clips with points and the C-clamp with a point are perfect for this application.
Once a connection is made to the first container a “daisy chain” method of connecting the remaining containers in the area can be used. This means that a grounding cable can be attached from container to container to maintain a good ground as long as the series of containers is attached to the one connected to the grounding source. Keep in mind that each grounded container must have a solid metal-to-metal connection with the grounding device. It may be necessary in more caustic environments to wire each container directly to the grounding source. This same approach can be applied to grounding pipes for fluid flow, and even grounding work stations.
Following the above steps for creating a solid grounding system should produce good results and create a safe environment. To confirm that there is good connectivity, take resistance measurements with a multi-meter, ohm-meter or ground analyzer. To ensure entire system integrity, a lead should be placed on the connection on the grounding source (grounding pin or buss bar) and the other on the very last connection in the system. This will incorporate a resistance measurement from point-to-point for the entire grounding system. If the reading taken is zero or approaching zero, the system is well grounded and a safe environment exists. If the reading approaches 1M Ohm then check the connections throughout the system to ensure that there are solid metal-to-metal connections. Once the appropriate measurement is received (zero or approaching zero), you have a good and well-grounded system in place ensuring static protection.
