RF SHIELD BOX

LBX4250 RF Shield Box

Name: LBX4250 Benchtop RF Shield Box | LabiFix
Brand: Labifix Innovations
SKU: LBX4250

LBX4250 provides a useful starting point for controlled wireless testing, with configuration options that can be matched to the test setup. Its configuration can bring together RF Gasket System and User Defined & Interchangeable I/O Connector options so engineers can balance shielding, connectivity and access without forcing the DUT into a fixed setup. It is well suited to controlled RF validation, development and production test workflows where repeatability matters. For teams searching for a RF test enclosure supplier in India, LBX4250 can be considered as part of a tailored RF shielding solution.
