High-quality #waterproof #IP67 RJ45 Ethernet Connector System by Wireless Instruments (www.wireless-instruments.com) 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 #RJ45adapter 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.
