Initiators
The European standard initiator 1TAPWH40 is a medium-power electropyrotechnical initiator.
A range of 1A/1W/5mn NF initiators is available according to:
- the desired pyrotechnical effect: a flame (igniter), a pressure wave (squib) or a shock wave (detonator),
- the requested technical performance (mechanical interface being standard).
