Supports 430MHz to 6GHz, with a response of -60dB or higher. Automatic opening and closing 'Shield Box PSB-300A' with air cylinder.
Protech's "Shield Box - Radio Wave Absorbing Box" 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 (Wi-SUN) represented by the 920MHz band. It can be widely used from production to quality control and development. The radio wave absorbing box prevents radio wave scattering by covering the inside of the box with a radio wave absorber, minimizing the impact on device inspection. The Shield Box PSB-300A is a shield box that enables automatic opening and closing by adding an air cylinder to the PSB-300, utilizing an air cylinder opening and closing mechanism. The external dimensions are W470×D550×H270 (base dimensions) and W250×D300×H250 (box dimensions). It supports frequency bands from 430MHz to 6GHz, with shielding performance of -60dB or more. As it is an automatic opening and closing type, optional area sensors can be installed around the box to ensure safety during opening and closing. 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.
