Two-pin structure:
Standardized dimensions：
Standardized structural dimensions ensure consistent mounting.
Customization support:
Structure and pins can be adjusted to customer requirements.
Optical communication:
Used for laser and detector packaging.
Sensors:
Suitable for sensor element packaging.
Stable hermeticity:
The GTMS process ensures hermetic and insulation performance.
Fast response:
Mature production lines enable rapid sampling and mass production.
The TO9 2P2L header sinter-seals the two pins to the metal base through glass insulators. After high-temperature sintering, the glass forms a dense bond with the metal, providing hermetic sealing and electrical insulation. The element is mounted on the base, and electrical signals are led out through the pins. The 2P2L structure provides dual electrical connections for specific applications, and the hermetic cavity protects the internal elements from environmental influence.
