EMI and RFI Shielded Enclosures
High-performance EMI and RFI shielding solutions for electronic enclosures where signal integrity and interference control are critical.
EMI vs RFI Shielding – What’s the Difference?
EMI (electromagnetic interference) is the broad term for any unwanted electromagnetic energy that can disrupt electronic performance across a wide range of frequencies.
RFI (radio frequency interference) is a subset of EMI, referring specifically to interference within the radio frequency range—commonly impacting wireless communication systems like Wi-Fi, GPS, and cellular signals.
In practice, most systems need protection from both. Understanding how interference behaves across frequencies is key to selecting the right enclosure and shielding approach. For a deeper look at how EMI and RFI shielding impacts system performance, read our blog.
EMI and RFI Shielded Enclosures
At Lansing, we specialize in high-performance EMI (Electromagnetic Interference) and RFI (Radio Frequency Interference) shielded enclosures engineered to protect your sensitive electronics and ensure compliance with critical industry standards.
All of Lansing’s standard GrayBox and MicroPak electronic enclosures provide inherent EMI and RFI shielding through aluminum construction, with additional customization options available to enhance shielding performance for specific application requirements.
Shielded Enclosure Solutions – Added Protection for Sensitive Electronics
- Remove nonconductive anodized finish from the outside of the top & bottom flanges; Clear iridite the raw aluminum
- Use vinyl-clad aluminum instead of anodized aluminum covers. Inside surface has an iridite finish
- Add center-front and center-rear screws on each cover to enhance electrical contact
- Choose captive nuts vs. speed nuts
- For non-cosmetic applications: Choose clear iridite finish (conductive) for the tube and end panels
- For cosmetic applications: Ends and tube interior can be masked and iriditied while exposed surfaces are powdercoat painted
- Choose Nickel acrylic (conductive) paint on all or selected surfaces
- Select clear iridite finish for end panels
- Choose nickel acrylic (conductive) painted bezels on all or select surfaces
- Substitute vinyl-clad aluminum with a conductive iridite interior surface for the standard vinyl-clad steel with a nonconductive painted interior surface
