Pneumatic RF Shielding Test Box for Wireless Device Testing

Product Overview

This pneumatic RF shielding box is designed for repeatable wireless performance verification including power testing, sensitivity evaluation, and electrical performance measurement. It is suitable for smartphones, laptops, wireless servers, and communication terminals requiring stable electromagnetic isolation during production or laboratory testing.
The enclosure adopts a pneumatic opening structure to improve automation efficiency while maintaining reliable shielding consistency. Constructed with 2.0 mm metal sheet or stainless steel, the system ensures durability under continuous industrial operation.

The shielding effectiveness reaches 70–90 dB from 100 MHz to 6 GHz, providing a controlled RF environment for accurate measurement results. Internal surfaces are lined with 10 mm flat microwave absorbing foam, reducing signal reflection and improving test stability.

Key Features

• Shielding performance: 100 MHz–6 GHz, 70–90 dB

• Pneumatic automatic opening for high-throughput testing

• Housing material: 2.0 mm sheet metal / stainless steel

• Internal absorber: 10 mm flat absorbing material

• Standard interfaces: USB2.0, DB9, DC, RJ45, SMA-SMA (customizable)

• Custom color and interface configuration available

• Designed for long service life in production environments

Applications

Widely used in RF production lines, R&D laboratories, and quality inspection departments. Typical testing includes WiFi, Bluetooth, mobile communication modules, IoT terminals, and wireless consumer electronics. The pneumatic design makes it ideal for automated testing stations where efficiency and repeatability are critical.
