Shielded Faraday Cage Box with External USB, BNC, HDMI, SMA or RJ45 Connector ( size 200mm x 120mm)

A rugged, lab-ready Faraday enclosure designed to isolate electronics from external RF/EMI while still allowing a clean, cabled connection to your test gear. The die-cast aluminium body and tongue-and-groove lid create a continuous conductive shell; a dedicated earth bonding point ensures a low-impedance path to ground. Choose a connector for Ethernet (RJ45), SMA, BNC, HDMI or USB, so you can stream data to a device inside the box without compromising shielding.

Key features

• All-metal enclosure: thick die-cast aluminium with smooth interior for easy device placement.
• Conductive lid interface: machined gasket channel for reliable RF sealing around the entire perimeter.
• Earth/ground connector: internal brass stud and external lug for fast, secure bonding to earth.
• Shielded data pass-through: panel-mount filtered bulkhead (RJ45, BNC, HDMI, SMA or USB) , maintains enclosure integrity.
• Quick-latch closure: positive locking latch for repeatable, tool-free sealing during test cycles.

Typical uses

• RF/EMI susceptibility and isolation tests
• Secure/forensic device examination (phones, IoT, key fobs)
• Pre-compliance EMC work and troubleshooting
• Protecting sensitive measurements from ambient interference

What’s included

• Faraday box with hinged lid and latch.
• External size of 200mm x 120mm.  Internal size of 138mm x 74mm.
• Earth grounding hardware (bonding stud/lug)
• Installed shielded bulkhead (select RJ45, BNC, HDMI, SMA or USB) 

Notes

For best performance, bond the enclosure to earth ground, use shielded cables on both sides of the feedthrough, and fully close the lid during operation.
