Sealed Electrical Connectors: Why Upgrade to Ceramic Seals
When engineers design seals for electrical connectors like feedthroughs, they typically consider four common materials. At the low end, simple epoxy resins or adhesives suffice. Alternatively, mechanical seals with elastomeric O-rings provide a more robust solution. For applications demanding more, glass seals effectively prevent leaks during extreme temperature, pressure, and humidity variations. For top-tier performance, ceramic seals reign supreme, boasting excellent heat resistance, mechanical shock resistance, and corrosion resistance. However, the superior performance of ceramics over glass comes at a cost. Ceramic materials are typically more expensive, and ceramic-metal seals require more complex engineering and manufacturing processes. Innovacera suggests using ceramic seals when glass seals fail to meet demanding performance requirements. For instance, aerospace applications demand high heat and mechanical shock resistance, while medi...
