Initiation and Ordnance

Teledyne Reynolds has a specialized area of expertise in high voltage interconnect solutions and high energy devices for initiation and ordnance (I&O) applications. These highly engineered products have various characteristics tailored to I&O. Depending on the product, characteristics can include controlled impedance and capacitance values, low impedance flat cable compatibility and precise switching times.


Applications come from many markets, including

  • Mining
  • Sub-sea exploration & production
  • Research & development programs
  • Geophysical applications
  • Military/Defense (such as ordnance disposal and flight termination systems)
