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).
