We also carry pyrotechnic initiators, which produce heat and pressure to kindle hard-to-ignite materials like propellants, safety fuses, and thermal battery systems. Initiators are operated electronically using heated devices called bridgewires. Bridgewires are similar to detonators but do not produce shock waves — instead, they generate exothermic chemical reactions to set off pyrotechnic compositions.
These dual or single bridgewire units are small, lightweight and designed to maximize efficiency, output and reliability. With over 200,000 units manufactured and flown worldwide, these units can provide a simple way of achieving critical design criteria.
The initiators can be electrically actuated with as little as 3.5 amps (though lower actuation amperage is achievable) with a peak pressure of 1200 PSIG within milliseconds from actuation.
