At Accu-Tech, we know how important the life of your products are for your business, and your bottom line. In an effort to improve the electrical and mechanical performance of the traditional RJ-45 jack, Siemon invented and patented a curved or “crowned” contact shape for its MAX® and Z-MAX® RJ-45 jacks. In addition to achieving the industry's highest transmission performance and eliminating the risk of permanent contact deformation due to mechanical stress, Siemon’s patented crowned jack contacts provide superior support for remote powering applications.
Unmating a jack-plug connection under a PoE load produces an arc that erodes the gold plated jack-plug contact surfaces at the arcing location. When this erosion occurs in the area of the fully mated position, the result is an unreliable connection. Only Siemon’s crowned jack contact geometry places arcing damage to both the plug and jack contacts away from the final mated position—allowing you to connect and disconnect to the latest PoE applications with zero risk. Learn more about the effects of erosion with Siemon.
As PoE standards advance for higher power delivery over all four pairs of a network cable, it just might be time to pull the plug on inferior connections and choose Siemon’s patented crowned contact—it’s what makes these jacks the King of PoE.
