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.
Electrical Characteristics Range
The characteristics listed below represent the range of specifications of all the standard product types in the Series.
| Bridgewire resistance | ≤ 0.1 to 180Ω |
| All fire current (1) | 0.01 to 25A |
| No fire current (2) | 0.03 to 4A |
| Recommended current (3) | ≥ 0.9 to 30A |
| Reaction time | 2 to 5ms under 0.3 to 10A |
| Test current | ≤10mA |
(1) Minimum current which will activate the fusehead. Higher than 99.9% initiation with a 95% confidence level.
(2) Highest current which will not activate the fusehead. Less than 1% initiation with a 95% confidence level.
(3) Recommended current for in-series firing.
