Hi-Shear is the primary qualified source for the NASA Standard Initiator (NSI) used for
all initiation functions on the Space Shuttle. The NSI performs from an incredible low
temperature of -420°F to a high of +320°F. Only NASA now distributes the NSI. However,
the NSI "equivalent" alternative is our PC-23 initiator. It is utilized in all
non-NASA space and major defense programs where the NSI was previously used. Our PC
series meet Range Safety Standards for RF & EMI hazards, and 5 minutes 1 Amp / 1 Watt
No-Fire test. The PC 117 series meets MIL-DTL-23659. Applications: |
