S Series Electric Fusehead and Igniter
The S Series Electro-Explosive devices consist of two tinned brass arms embedded in a polymer clip. The bridgewire is welded and crimped at the tip of the arms and then coated with a primary reactive composition and an energetic charge. The interface hardware is welded to the fusehead terminals per customer specifications.
The robust base structure provides excellent resistance to environmental constrains. Various types of shrouds and plugs are available to best fit the application and integration in any systems.
