Ceramic Hermetic Seals

In recent years, there has been a strong need for components that are used in electronic devices to be applicable in high-vacuum ranges, and to have a high degree of fineness and precision. As this trend continues, the materials used in products have been shifting from resin and glass to ceramics, in order to respond to the need for improved quality. MARUWA's ceramic hermetic seals use ceramics Al₂O₃, etc.) as the insulating hermetic materials and maintain airtightness in high-vacuum ranges, so they eliminate concerns about aging deterioration. In addition, their applicability and reliability in high-temperature ranges has also been enhanced. Thanks to these characteristics, our ceramic hermetic seals are widely used in devices and equipment for fields related to space, medicine and nuclear power - areas that particularly require compatibility with high-vacuum and high-pressure conditions.

• Standardized 3-pin to 48-pin connector terminals compatible with the MIL-DTL-5015 standards.

• Thermocouple types use thermocouple equivalents or compensating lead wire materials.
