Product Description
EMI Shielding Honeycomb Vent Panels are high-performance, cost-effective components designed to provide both electromagnetic shielding and airflow management in telecom applications such as base stations and network cabinets. Built to meet NEBS and Bellcore GR-63-CORE standards, these panels ensure compliance while maintaining system ventilation and shielding integrity.
Traditional ventilation openings often become EMI leakage points, especially in high-density electronic enclosures. These honeycomb vent panels solve this issue by delivering low-resistance airflow while providing reliable EMI suppression, helping equipment meet stringent regulatory and operational requirements.
Compared to conventional metal mesh or perforated vents, our honeycomb panels offer superior shielding effectiveness, customizable frame and plating options, and enhanced mechanical strength, making them ideal for both retrofit and new equipment designs in critical communication infrastructure.

Typical Applications
The EMI Shielding Honeycomb Vent Panels enables precise orientation of base stations during testing, ensuring consistent signal exposure and accurate electromagnetic compatibility evaluation.
In network cabinet testing, the EMI Shielding Honeycomb Vent Panels allows controlled rotation to assess emissions and susceptibility from different angles without repositioning heavy enclosures.
Shielded rooms benefit from the EMI Shielding Honeycomb Vent Panels by enabling automated DUT rotation inside confined EMC test environments, improving efficiency and measurement consistency.
For shielded cabinets, the EMI Shielding Honeycomb Vent Panels supports seamless integration and smooth rotation of bulky devices under test, enhancing overall EMC test reliability.
