Shield Box PSB-400 compatible with 430MHz to 6GHz, capable of supporting over -60dB.
Protech's "Shield Box - RF Shielded Enclosure" provides an environment that "blocks external radio waves and prevents internal radio waves from leaking outside" for the inspection of various communication devices, including smartphones, tablets, wireless LAN (Wi-Fi), Bluetooth, and low-power wireless communications in the 920MHz band represented by smart meters (Wi-SUN). It can be widely used from production to quality control and development. The RF shielded enclosure prevents radio wave scattering by covering the interior of the box with a radio wave absorber, thereby minimizing the impact on equipment inspection. The Shield Box PSB-400 is one of the standard models in the PSB series. Its external dimensions are W350×D400×H250 (box exterior), it supports frequency ranges from 430MHz to 6GHz, and its shielding performance exceeds -60dB. For more details about the product, please refer to the catalog. *We offer a wide range of lineups based on external dimensions, shielding performance, specifications, and more.
