⇒EMS Panel
Our unique multi-layered shielding material has broadband shielding capabilities, from static magnetic fields to several tens of GHz. Developed for pacemaker protective clothing, this material is lightweight and soft.
This shielding box is capable of shielding a wide range of frequencies, from static magnetic fields and power frequencies such as 50Hz/60Hz to millimeter waves of 60GHz and above. It is a lightweight shielding box made using our proprietary shielding material "EMS Panel." It is also insulated so that circuit board testing can be performed. It can also accommodate the installation of various I/O connectors depending on the application.
- ■Door opening image
- We have taken various measures to ensure that the joint with the door is tightly sealed and conductive.
- ■Opening, panel fixing part
- In order to ensure shielding performance, we have taken great care in designing and manufacturing the product to increase electrical airtightness.
- ■Door fixing part
- We also devise innovative fixing methods to eliminate gaps created by the door. We also design and manufacture products that take into consideration convenience and shielding performance, such as magnet types.
- ■Rear
- Various I/O connectors can be attached. Connectors can also be installed on the side. In addition, the number and types of connectors can be manufactured according to specifications.
- ■Enlarged image of the connector panel
- Depending on the type and quantity, the size of the panels will be changed and then fixed into the frame.
- ■Image from inside
- We design the installation location of the connector panel based on factors such as how the cables to be connected to the connector will be routed and the shape of the objects to be shielded inside the box.
- ■Handle processing
- We design and manufacture our products with portability in mind.
