The RF shielded doors employ knife edge technology to maintain perfect electrical contact between the door leaf and frame. The door leaf is a single panel with a wooden core and galvanized steel sheets, surrounded by a welded brass profile. This design ensures long-term reliability and high shielding effectiveness.

Aluminum hinges, precision-machined, prevent twisting even with heavy absorbers, ensuring long-term stability and performance.

SIEPEL has over 20 years of experience in manufacturing shielded rooms for various applications, including EMC anechoic chambers and TEMPEST shielded rooms.

Guaranteed attenuation values are provided for different frequencies, with typical values often exceeding these guarantees. The effectiveness is measured according to standards like EN 50147-1 and MIL-STD-285.

• H-Field: 10 kHz - 55 dB, 100 kHz - 80 dB, 1 MHz - 100 dB
• E-Field: Up to 1 GHz - 120 dB, 10 GHz - 100 dB, 18 GHz - 80 dB

Standard dimensions range from 900x2100 mm to 1500x2400 mm, with custom sizes available.

A rotating handle actuates a stainless steel axis with rollers that ensure perfect electrical contact when the door is closed. The system is designed for easy maintenance.
