Ensure Adequate Cable Shielding for Application Needs:
In environments with typical electromagnetic interference, metal foil shielding alone is usually sufficient to provide adequate noise protection. However, in high-noise environments, a combination of braided mesh and metal foil shielding is recommended for enhanced protection.
Select the Right Shielded Cable for the Environment:
Choose a shielded cable based on the specific application requirements. For instance, cables that undergo frequent bending should use spiral-wound shields instead of braided mesh. Similarly, flexible cables should avoid relying solely on metal foil shields, as repeated bending can cause the foil layer to tear or crack.Ensure Proper Grounding of Connected Equipment:
Effective grounding is critical for minimizing electromagnetic noise. Whenever possible, use a solid earth ground and verify the connection between the grounding point and the equipment. The effectiveness of noise elimination depends on maintaining a low-impedance ground path.Use 360° Shielding Connections for Devices and Connectors:
Many devices and connectors are designed to support 360° shielding, ensuring a reliable connection to the cable shield. For example, common connectors often feature housings made of metal-coated plastic, cast zinc, or aluminum. Always select connectors that match the shielding performance of the cable to avoid compromising shielding effectiveness or incurring unnecessary costs due to over-specification.
