Hermetic vs. non-hermetic sensor packaging

Packaging components play a critical role in long-term sensor performance, reliability, and accuracy. While polymer-based and hermetic solutions may deliver similar initial results, their performance can differ significantly over time as moisture, gas diffusion, and environmental exposure begin to impact sensor stability.


Hermetic packaging creates a stable internal environment that helps reduce the risk of signal drift, improve reliability, and support compact, high-performance sensor designs for demanding applications.


In this guide, you'll discover:


  • The measurable differences between hermetic and non-hermetic packaging
  • The importance of moisture control in maintaining stable internal conditions
  • The technical features hermetic packaging components can provide beyond environmental protection
  • Design considerations related to integration, miniaturization, and long-term system behavior


Learn how the right packaging strategy can improve sensor reliability, accuracy, and long-term performance.
