More than 40 years of developing and manufacturing
hermetic interconnections.

Experts in Glass-to-Metal Technology

VAC-TRON, S.A. began its operations in 1985 and has become a specialist in the development of hermetic interconnection solutions for transmitting electrical signals between isolated or hostile environments.
Our core expertise lies in Glass-to-Metal Seal (GTMS) technology, which enables us to create a permanent hermetic seal by fusing glass between electrical conductors and metal housings or
bulkheads. This process ensures optimal sealing integrity under the most demanding conditions.
