Due to uncertain times and the need to streamline manufacturing processes as much as possible while turning the best profit, technological advancements have been made in every industry and are now being heavily implemented everywhere. By now you’ve heard all about Industry 4.0 and how it can be applied to factory automation. But how does this effect your packaging needs and that of the packaging industry overall? Here are some of the top automation trends for packaging in 2022 and how these trends can help your business.

Robots & CoBots
The most obvious automation trend is using robots and cobots to automate such packaging tasks as filling, packing and palletizing. Robots are used to perform just about any repetitive task such as assembly, machine tending, quality assurance, palletizing and picking-and-placing tasks. CoBots, short for collaborative robots, can do the same and are often utilized where more than one robot is needed to perform a sequence of tasks. Because CoBots are premade with safety-compliant designs, CoBots are typically rented or leased and are especially great to use in conjunction with human applications or in areas where people work on the production floor.

End-Of-Arm Tooling (EOAT) for robotics
EOAT is being used more and more in packaging as many technological advances have been recently made. Developments include robotic hands that now have sensitive grip and can automatically adjust through Artificial Intelligence (AI), making this function useful for picking and packing applications.

For example, the idea of EOAT being used to pick and pack food items as delicate as tomatoes or grapes hasn’t been considered until now due to the risk of crushing items, however; because of newly-designed soft, spring-like fabricated fingers can sensitively adjust grip on objects, the application is now a reality. What’s more, EOAT changeovers needed for running different jobs has been a chore in the past, producing a lot of unwanted downtime with needing to unbolt one tool, bolt on another and, in many cases, having to change programming to accommodate the new job to be run. Because of EOAT advancements, however, operators are now quickly able to swap out one tool for another during change outs, along with grippers, scanners and packaging tools. Some new EOAT can also be used among different types of robot arms and models, instead of just one, making them convenient to use for multiple applications and compatible with different styles of robots and cobots.

NEW ADVANCEMENTS IN EOAT ROBOTICS WITH SENSITIVE GRIPPERS, POWERED BY AI, ALLOW FOR NEWFOUND APPLICATIONS IN FOOD PICKING AND PACKAGING.

Machine Learning / AI-Vision Systems
Machine learning, such as what is used in Artificial Intelligence-vision systems (referred to as AI), can help greatly in packaging as well. AI-vision systems can be used for inspection purposes and for lowering costs associated with inspection. Adaptable systems, such as the AI Gateway from Pleora Technologies, can be integrated with current cameras, sensors and equipment and can be programmed to update your existing systems for added functionalities. AI-vision systems can be of special use in food picking and packaging as they can inspect produce and predict shelf life which can help immensely to reduce waste. AI-vision systems are also being used more and more often in a variety of ways to enhance quality control, inspection and production efficiency, such as by taking pictures of completed products to examine package quality.

THROUGH MACHINE LEARNING, SENSORS AND CAMERAS CAN DETECT DEFECTS, AS WELL AS RECOGNIZE WHICH APPLES ARE NOT AS RIPE AS OTHERS AND SEND THEM TO BE USED IN A SEPARATE FOOD CLASSIFICATION. ALL OF THIS IS DONE AT HIGH RATES OF SPEED TO IMPROVE FOOD QUALITY AND REDUCE LABOR COSTS. TO THE RIGHT, PHOTONICS IS USED TO INSPECT THE RIPENESS OF STRAWBERRIES FOR PICKING AND PACKAGING. PHOTONICS CAN ALSO BE USED TO PREDICT THE SHELF LIFE OF PRODUCTS AND GREATLY REDUCE WASTE.

Food Packaging & Processing
The key to more profitable food packaging is knowing what goods should be produced in large amounts to yield the greatest profit margins. Technology can certainly help in this department. Automation is now being used to enhance packaging, as well as improving food safety and increasing shelf life.

All these automation trends are currently being used in packaging as well as in all types of factory automation, however; due to universal pressures to continue manufacturing processes while turning a profit during labor shortages has caused plant managers and staff to implement and rely more and more on automation as a solution.

M12 Connections Explained: What Are They & Which Are Best For Your Purpose?

Posted by Deanna Craver on Apr 5, 2022 1:20:03 PM



M12 CONNECTIONS EXPLAINED:
WHAT ARE THEY AND WHICH ARE BEST FOR YOUR PURPOSE?

With so many various types of
M12 connections and options to choose from, such as pin count, pin positions, connection coding and IP ratings, the selection process can seem rather overwhelming. What does it all mean and how do you know which connections are right for your specific application? This article will explain these terms, what all of them mean as well as all of their classifications, so that you can discover which M12 connections are right for you. 


M12 CONNECTIONS … WHAT ARE THEY?

The name M12 came about pretty simply: M stands for the unit of measurement taken (in this case, metric) and 12 stands for the length of the diameter taken across the outside of the threads (12mm). M12s have circular connections and, because of their circular shape, they possess high current capabilities and are much easier in obtaining ingress protection (IP) ratings, or ratings that tell how well connections are able to keep out elements such as dirt, sand and water, than their rectangular counterparts. This makes them an excellent choice for use in factory automation applications, or in any tough or harsh environment where dirt or dampness is involved. 


PIN COUNT

Choosing the right M12 connections depends on your specific application. M12 connections come in a variety of pin positions, anywhere from 2, 3, 4, 5, 6, 8, 12 and 17 pins. The number of pins varies depending on the signal type and number of signals, connection coupling and code.
 

Pin counts differ according to code. Connections with B code, which are used for Profibus connections, typically have 5 pins, although their pin count can vary from having 3-5 pins. Connections with C code, which are used for AC power applications, usually have 6 pins, although their pin count can also vary from 3-6 pins. Connections with D code, which are used for Ethernet applications involving data transfer of up to 100 Mbits, always have 8 pins. Connections with A code, on the other hand, are used as all-purpose connections in such a wide variety of factory automation applications, such as attaching to sensors, actuators and a number of other smart devices, that the pin count can be anywhere from 2-17 pins. 


PIN POSITIONS AND CONNECTION CODING

Different pin positions have been created to coincide with the different types of coding that have been devel- oped according to function. This way the pin positions act as a fail-safe and eliminate any mistakes of cables being connected that were made for different coding. For instance, you would certainly connect cables that both have A-coding and are being used to hook up sensors with corresponding equipment, however; you would not want to connect an AC power cable to an Ethernet cable. 

Present coding

 

CODING FOR DATA APPLICATIONS

Below is a description of the different coding classifications currently used in factory automation and what they mean.

A-CODING
A-coding (also known as Micro-DC) for factory automation cables is the most widely used coding in factory automation applications of all the types. These connections are used in data applications primarily involving DC power. A-coding is used for attaching actuators, attenuators, sensors, motor-operated switches and other devices to automation equipment. A-coded connections are also used to transfer up to 1-Gbit of data in Ethernet applications and can have anywhere from 2 to 17 pin positions.

B-CODING
B-coding is unique in that it contains a reversed single keyway, which allows 2 unique M12 connections to be mounted on the same panel without the risk of incorrectly coupling connections to equipment with varying voltage and amperage. B-coding for factory automation cables is used in fieldbus connections involving Profibus and Interbus. B-coding connectors typically have anywhere from 3 to 5 pins.

C-CODING
C-coding (also known as Micro-AC) is strictly used in cases where AC current is involved, such as with AC actuators, sensors and other AC devices. Because of this C-coding is not as commonly used as the other coding types. Connections with C-coding all have extended grounding pins and double keyways for added safety to prevent them from being mistaken for other similar-looking connections or being coupled with the wrong cables. C-coding connections have anywhere from 3 to 6 pins.

D-CODING
D-coding is specifically used in network cables for industrial Ethernet applications to transfer data up to 100-Mbits. The insides of cables with this type of coding consist of either 4 wire connectors (D-coding) with 2 pairs of Cat 5e cables or else M12 8 wire (A-coding) connectors with 4 pairs of Cat 5e cable. D-coding can also be used with Profinet, Ethernet/IP and EtherCat systems. D-coded connections usually have 3 to 5 pins.

X-CODING
X-coding has been introduced in the recent years and is quickly becoming a standard for use with high-speed industrial Ethernet applications. X-coding has capabilities of transferring large amounts of data at high speeds, up to 10-Gbits of data. X-coding is expected to eventually replace A- and D-coded parts for Ethernet applications. X-coding applications include high-speed industrial Ethernet and Cat6A. X-coded connections always have 8 pins. 

 

Soon-to-be coding

 
CONNECTION CODING FOR POWER APPLICATIONS
While A, B, C, D and X connection coding make up the majority of factory automation cable use today, new coding is being introduced as well. K, L, S and T coding are all used for power applications. Rapid advancements in Industry 4.0 technology have resulted in these codings providing improved performance in specific power operations. S- and K-coding are both used for AC power applications and it is believed that S-coding will at some point take the place of C-coding that is currently used. T- and L-coding are both used for DC power applications and it is believed that T-coding will at some point take the place of A-coding that is currently used. P-coding has also been developed for various uses where quick connects and disconnects of cables are needed.


IP RATINGS
As mentioned earlier, the circular shape of M12 connectors makes it easy to assign them IP ratings which classify how well connectors are able to block out unwanted elements that can cause corrosion and other problems. Because of the rugged design of M12 connections, they are an ideal choice for use in factory automation.

The International Electrotechnical Commission (IEC) came up with these rating classifications and international standards which set the bar for what connections can withstand. There are three common IP standards associated with M12 connections which are IP67, IP68 and IP69.

What are the differences?
The first digit (in this case, the number 6 in all three ratings given) refers to the connection’s resistance to solid objects, such as dirt, sand or dust. The significance of the number 6 means that after being in contact with solids for 8 hours, the connection does not absorb any “harmful” dirt and it is still functional. The second digit refers to the connection’s resistance to water. In the examples given we have 7, 8 and 9.

The significance of the number 7 means that the connection can be submerged in a greater depth of up to a 1 meter of fresh water for half an hour and still be water resistant. The significance of the number 8 means that the connection can be submerged in up to 1.5 meters of water for a half an hour and still be resistant. The significance of the number 9 means that the connection can actually withstand high pressures, high-pressure jet sprays, wash downs and steam cleaning procedures.


MAKING YOUR SELECTION
Now that you know about pin counts, pin positions, coding and ratings, you are ready to select your connections. Mueller Electric can help you with the process. Mueller Electric’s M12 factory automation connections have the most reliable and efficient connection standards for industrial machinery and industrial automation applications. Having high-performance capabilities, small footprints and extremely low failure rates, Mueller Electric’s connections are ideal for use in the toughest conditions.

Posted by Deanna Craver on Oct 5, 2021 3:57:19 PM

INSTRUMENTATION CABLES:

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.  

                                                             PVC
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.

                                                     PUR
Polyurethane offers good resistance against abrasion, oil and ozone. PUR is halogen free, meaning it does not contain chlorine, iodine, flourine, bromine or astatine. 

                                                             TPE*
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.
