RF/EMI Shield Spiral Gasket (O-Ring)

Overview

EMI shielding O-Ring gasket
  • High elastic Sn/Ni plated beryllium copper or stainless steel plate is made into a spiral, so it has excellent elasticity and flexibility and guarantees high shielding effectiveness
  • Due to its excellent electromagnetic shielding effect, it is mainly used for semiconductor etching equipment, precision medical equipment, and communication equipment that require high electromagnetic shielding performance.
  • Suitable for EMI shielding of the circular connector (Jam nut connector).

Features

  • Excellent electromagnetic shielding effect of more than 100dB
  • Precision spot welding processed on connecting parts
  • Easy to do groove mounting
  • Ribbon strip (plate) material, OD/ID size selectable
  • RoHS Compliant
