High-quality waterproof IP67 RJ45 Ethernet Connector System - guaranteed waterproofing of the connection on the enclosure. That solution is universal for M20 standard hole. It can be used to almost every outdoor enclosure where Ethernet cable is necessary. The RJ45 adapter has shielded and short-body RJ45 connector. It performs also D-cut on the M20 thread to block the adapter against twisting during the installation. Great stuff for PoE supply.
