Ceramic-to-metal sealed terminals and feedthroughs for all types of electrical applications. These sealed terminals are designed for applications where physical strength and long term hermeticity are important considerations. EnvirOptics ceramic-to-metal terminals use high purity alumina insulators, which are hermetically joined to their metal members by a variety of brazing and joining techniques. As a result of this wide assortment of joining methods, the seals perform well in a broad array of applications. The high purity alumina in these sealed products provides superior electromechanical, thermal and chemical properties to those made with glass or quartz.

Typical Applications Include:

• Semiconductor Processing Equipment
• In-Vacuum Coating
• Satellite Instrumentation
