HPP Series Initiator – High Level of Safety

Under control

Originated from the automotive safety industry, the HPP Series Initiator is ideal for ignition that requires fast, repeatable function time and tightly controlled firing characteristics.

The HPP Series Initiator is a line of low-cost electro-explosive devices designed and qualified to provide rapid reliable initiation of a burning or explosive reaction by the emission of hot gases and particles. These devices are extremely efficient in converting electrical energy to explosive energy in order to produce an ignition output.

MIL-DTL-23659E Specifications

Hermetically sealed and capable of the recognized 1A/1W 5-minute no-fire condition, 25-kilovolt electrostatic discharge protection, and high auto-ignition temperature: these characteristics provide a high level of safety in full compliance to MIL-DTL-23659E.

When needed, the HPP Series initiator is designed to meet customer’s specific requirements such as firing characteristics, output charge, interface, cable or leadwire, as well as immunity to electrostatic discharge (ESD), voltage blocking for Radio Frequency (RF) protection and very low initiation energy applications. The HPP Series Initiator has superior no-fire performance.
