Shielded Usb 3.0 coupler: the industrial bulkhead adapter and two female USB-A connectors are designed to withstand dust, debris and moisture that could threaten your it infrastructure. An included dust cap protects the connectors when they aren't in use. IP67 rating: the IP67 rating means the USB3 coupler is not only 100% protected against dust, But also able to endure immersion in one meter of water for up to 30 minutes with no damage or decline in performance, making the coupler ideal for basement applications. Heavy shielding: the u325-000-ind’s shielded construction helps fight against EMI/RFI line noise that interferes with your signal and can distort or destroy data. Electromagnetic interference and radio frequency interference can be created by electric motors, power cables, welding equipment and other heavy machinery frequently found in industrial applications. Supports USB 3.0: This USB 3.0 coupler supports data transfer rates up to 5 gaps—10 times faster than USB 2.0. Its bi-directional data interface allows data to flow both directions simultaneously, increasing theoretical bandwidth by 10 times for efficient power and little wait-time.
