M12 Cable Material Selection Guide: PUR vs. PVC vs. TPE
May 20, 2025
M12 Cable Jacket Materials: Which is Best for Your Requirements?
M12 Cables have become the industry standard for sensor/actuator connectivity in industrial automation environments. When selecting the right M12 cable for your application, the jacket material is one of the most critical factors that will determine performance, durability, and reliability. This guide compares the three most common M12 cable jacket materials: PUR (Polyurethane), PVC (Polyvinyl Chloride), and TPE (Thermoplastic Elastomer).
Why Material Selection Matters
The right cable jacket material can mean the difference between a reliable connection that lasts for years and frequent cable failures resulting in costly downtime. In fact, according to industry research, up to 70% of field failures in industrial networks are related to cabling issues. By understanding the properties of different materials and making informed selections, you can significantly improve your system’s reliability.
