Shield Enclosure
Overview
- Shielded enclosure (EMC Tent) of various sizes can be easily used when it is difficult to install a shielded room due to space and cost problem.
- Box type shielded enclosure is recommended for small device test, and room type shielded enclosure is recommended when operation in large equipment or shield space is required.
- Easy to move / install / disassemble due to the prefabricated structure, and excellent shielding effectiveness by made of conductive fiber material and double door structure.
Features
- Same performance as shielded room for less cost
- Excellent shielding performance
- Easy to move, install and disassemble with prefabricated structure
- So called, EMC Tent

Box Type Shielding Enclosure
- Suitable for testing small devices after installing on the table
- Easy to install and disassemble in a short time
- Shielding rate by frequency
| Frequency | 900MHz | 2.4Ghz | 5.9GHz |
|---|---|---|---|
| Shielding Rate (dB) | -61 | -47 | -41 |
※ In-house test according to IEEE-STD-299, Size: 500x500x500 [mm]
Double Layered Shielding Enclosure
- High shielding rate due to double layered enclosure cover
- It is a structure in which the inside and the outside are electrically separated completely.
- Double layered room type enclosure is avaiable.
- Shielding rate by frequency
| Frequency | 900MHz | 2.4Ghz | 5.9GHz |
|---|---|---|---|
| Shielding Rate (dB) | -74 | -71 | -54 |
※ In-house test according to IEEE-STD-299, Size: 700x700x700 [mm]
- Installation Features
Inner installation
Inner enclosure can be easily installed inside the outer enclosure using one-touch method
Support
By providing a support at the bottom between the inner and outer enclosure, even if the test equipment is placed inside the inner enclosure, it does not allow the shield rate drop by electric short.
Power passage
Insulation sheet is inserted into the power path between inside and outside to prevent short.
Shielding Pouch
- Small devices such as cell phones and circuit boards can be easily shielded inside the pouch
- Possible to form arbitrary space by inserting box or small frame
- Shielding rate by frequency
| Frequency | 900MHz | 2.4Ghz | 5.9GHz | |
|---|---|---|---|---|
| Shielding Rate (dB) | Fabric 10 Series | -36 | -30 | -30 |
| Mesh 20 Series | -24 | -20 | -21 | |
※ In-house test according to IEEE-STD-299, Size: 300x300x300 [mm]
