Key Design Points for Electromagnetic Interference (EMI) Resistance

2026,01,26

In complex industrial electromagnetic environments, anti-interference performance is one of the core considerations when selecting rigid-sheath connectors. Shielded contact designs typically adopt fully enclosed metal housings combined with dual-layer metal braided shielding, achieving electric-field isolation based on the Faraday cage principle and effectively suppressing high-frequency noise coupling.

For signal-transmission connectors, gold-plated or silver-plated contacts can reduce contact impedance, while PTFE insulation layers help minimize dielectric loss, ensuring that signal integrity meets the requirements of EN 61000-6-2. In addition, 360° circumferential spring crimping technology enhances electromagnetic sealing at the mating interface. Test data show that this structure can increase interference attenuation to 70 dB at 1 GHz.

Under extreme operating conditions, it is recommended to prioritize connectors that comply with the MIL-DTL-38999 Series III specification. Their triple-shielding structure has been verified to withstand a field strength of 20 V/m in accordance with IEC 61000-4-3 immunity testing standards.
