Manual Viewing Window RF Shielding Box

Product Overview

This manual shielding box with viewing window allows operators to visually monitor testing procedures while maintaining electromagnetic isolation. It is optimized for wireless product validation such as notebook computers, mobile devices, and communication modules requiring controlled RF environments.

The enclosure uses robust 2.0 mm metal or stainless steel construction and achieves shielding effectiveness of 70–90 dB across 100 MHz–6 GHz. Interior walls are covered with 10 mm flat absorbing foam to suppress internal reflections and enhance measurement accuracy.

Key Features

• Shielding effectiveness: 70–90 dB (100 MHz–6 GHz)

• Manual operation with observation window

• Durable metal shielding structure

• Internal RF absorber reduces standing waves

• Working space optimized for medium-size devices

• Standard RF/data interfaces configurable

• Custom dimensions supported

Applications

Ideal for laboratory debugging, engineering validation, and low-volume testing scenarios where manual interaction is preferred. Commonly applied in wireless module testing, RF calibration, and electronic product development environments.
