Electrical grounding is essential in electrical systems not only for safety but also for minimizing electrical noise, which can disrupt electronic circuits, affect precision sensor readings, and cause malfunctions in sensitive devices.
Grounding reduces electrical noise through several mechanisms:
1. Stable Reference Voltage: Grounding establishes a common reference voltage (usually 0V) for all electronic circuits in the system, ensuring accurate signal measurements and reducing noise impact.
2. Low-Impedance Noise Path: By providing a low-impedance path, grounding directs noise currents away from sensitive components, preventing interference and improving system performance. Conductive gaskets, such as conductive elastomers, metallic fingerstock, and conductive foams, are often used to achieve this.
3. **Shielding Effectiveness**: Grounded metallic shields, when properly connected to ground, block or reflect electromagnetic fields, preventing noise from entering or leaving the system. Parker Chomerics products are designed for EMI shielding, serving as conductive interfaces between shields and grounded surfaces, whether in enclosures or on PCBs.
For various grounding needs, Parker Chomerics offers a range of solutions including:
- Electrically Conductive Elastomers
- Conductive Fabric-over-Foam
- Conductive Foam
- Metallic Fingerstock and Springfingers
- Metal Mesh Solutions
Grounding is vital for reducing electrical noise in electronic systems by providing stable voltage, low-impedance paths, and effective shielding, thereby preserving the performance and reliability of electronic devices.
