The RJ45 series Y-Con from Yamaichi Electronics was developed for the toughest industrial applications and is a flexible, modular and expandable product line. It meets the requirements of protection ratings IP20, IP67, IP68 and IP69K, among others. Within the product line, the Y-Con Cover-40, which has been established for years, has now been replaced by a new metal cover, namely the Y-Con Cover-40 PP with push-pull locking. It facilitates and simplifies handling, with the cover automatically locking or unlocking during the plugging or unplugging process.
