Electrical applications often operate in harsh environments where safety and performance are paramount. One critical component in ensuring the reliability of electrical systems is the hermetic feedthrough in pressure or vacuum. Hermetic feedthroughs provide an airtight barrier that protects sensitive electronic components from external factors such as moisture, dust, and gas, making them essential for a wide range of industries, from aerospace to medical devices. Below, we explore why hermetic feedthroughs are crucial for electrical performance and safety.
Preventing Electrical Failures
The primary function of a hermetic feedthrough is to prevent any leakage of gases or fluids into electrical systems. In electrical applications, even minor contamination can lead to catastrophic failures, such as short circuits or sparks. These failures pose risks, not only to the functionality of the system but also to the safety of operators. By creating a sealed environment, hermetic feedthroughs prevent moisture, fluids, gases and dust from entering the system or leaking of inert gases, reducing the risk of electrical malfunctions.
Reducing the Risk of Static Discharge
One of the most significant risks in high-performance electrical environments is static discharge. According to Heads Up, a spark of static electricity can reach up to 3,000 volts, which is enough to damage sensitive electrical components or ignite flammable materials. In environments like aerospace or medical devices, where precision is critical, such a failure could result in severe damage or even injury. Hermetic feedthroughs create an airtight seal that prevents the ingress of moisture or conductive materials, significantly lowering the risk of static discharge and electrical hazards.
Enhancing Durability and Longevity
Electrical systems exposed to fluctuating environmental conditions, such as extreme temperatures or high humidity, are prone to corrosion and degradation over time. A hermetic feedthrough acts as a protective barrier, ensuring that these external factors do not compromise the longevity and durability of the system. This increased durability is vital in industries like automotive and aerospace, where the reliability of electrical components is crucial for long-term performance and safety.
Hermetic feedthroughs play an indispensable role in maintaining the performance and safety of electrical systems. By preventing contamination, reducing the risk of static discharge, and enhancing durability, hermetic feedthroughs ensure the reliable operation of electrical systems in demanding environments. As technology advances, the need for robust and effective hermetic feedthrough solutions will continue to grow, providing a critical safeguard for a wide range of pressure or vacuum electrical applications.
