What is the difference between Electromagnetic Compatibility (EMC) and Electromagnetic Interference (EMI)?
EMI and EMC are both terms related to electromagnetic waves, but they describe different concepts. When inductive products operate, they produce an electromagnetic field. These fields can not only affect surrounding components and cause interference, but if the inductive product itself is not well shielded, it may also be affected by interference from other equipment.
In inductive sensors, EMC refers to the ability of the sensor to not produce excessive electromagnetic interference when near other electronic equipment, and to not be affected by electromagnetic interference from other electronic equipment. Ensuring EMC for inductive sensors is very important because if they produce too much electromagnetic interference, they may damage surrounding electronic equipment and affect their normal operation. If inductive sensors are affected by electromagnetic interference from other electronic equipment, they may lose accuracy or encounter other faults. Therefore, when designing inductive sensors, EMC requirements must be considered to ensure their EMC performance.
EMI, on the other hand, refers to electromagnetic interference. In inductive sensors, EMI refers to the electromagnetic interference they produce, which may damage surrounding electronic equipment and affect their normal operation. Ensuring that inductive sensors do not produce excessive EMI is very important because if they do, they may be prohibited from being sold on the market. When designing electronic equipment, most manufacturers consider EMC/EMI issues, so they use shielded or semi-shielded inductors. Coilmaster Electronics provides various solutions for shielded inductors, including surface mount, plug-in, or molded inductors, and we can provide the most suitable products according to customers' applications and designs.
