AB 04

Automatic shielding box(W)750
AB 04 is a medium size shielding box designed specifically for audio and RF testing of consumer electronics production lines. The goal is to provide a stable acoustic environment for audio testing of products. At the same time, the outer chamber is made of full sheet metal to ensure good electromagnetic shielding
AB 04 is applied to the occasions that require excellent rf isolation and ensure a better acoustic environment than the pure RF shielding box. 2 layers of complex sound insulation layer is realized on the limited wall thickness, and the sound insulation flannelcloth is used as the surface layer, which solves the unstable problem caused by the aging and damage of the wedge in the process.
This box is designed with 3 groups (6 channels) of air paths, which can meet the demand of automatic driving action in the box in the application of production line.
