Which cable jacket is best for your application?

There are many different types of cable jackets and each jacket works well in a specific application.  The three main sensor cable jackets are PVC (Polyvinyl Chloride), PUR (polyurethane) and TPE (thermoplastic elastomer). Each jacket type has different benefits like washdown, abrasion resistant or high flexing applications.  Finding the correct jacket type for your application can extend the life of the cable.PVC

PVC is a general purpose cable and is widely available.  It is a common cable, and typically has the best price point.  PVC has a high moisture resistance, which makes it a good choice for wash-down applications.

PURPUR is found mostly in Asia and Europe.  This cable jacket type has good resistance against abrasion, oil and ozone.  PUR is known for being Halogen free, not containing: chlorine, iodine, fluorine, bromine or astatine.  This jacket type does have limited temperature range compared to the other jacket types, -40…80⁰C.

TPETPE is flexible, recyclable and has excellent cold temperature characteristics, -50…125⁰C.  This cable is resistant against aging in the sunlight, UV and ozone.  TPE has a high-flex rating, typically 10 million.

The table below details the resistance to different conditions. Note that these relative ratings are based on average performance. Special selective compounding of the jacket can improve performance.

Choosing the right jacket type can help reduce failures in the field, reducing downtime and costs.  Please visit www.balluff.us to see Balluff’s offering of sensor cables in PVC, PUR and TPE.

Protect Your Sensors – Implement the 3-Step Process

When installing sensors into a harsh environment, for example a weld cell application, protecting the sensor is a crucial step in the installation process.  These sensors are exposed to extreme heat, weld slag and sometimes impact.  In order to reduce sensor usage, the sensor needs to be protected from the harsh area of exposure.  This can be achieved by using a complete sensor protection method that includes proper sensor selection such as sensors that have a weld slag resistant coating, proper mounting and cable protection.  If you follow these steps the end result will be longer sensor life.

  • Step 1
    • Identify form factor (size of sensor)
    • Output polarity (DC 3wire PNP, NPN etc.)
    • Identify special sensor characteristics (Slag resistant coating, SteelFace, F1 etc.)
  • Step 2
    • Select your mechanical protection system (ProxMount etc.)
  • Step 3
    • TPE cable
    • WeldRepel tubing and wrap

So, by simply implementing the three step total solution into your harsh or extreme application you can protect and lengthen the life of the sensors and cables providing less downtime.
