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:

Hi-Shear is the primary qualified source for the NASA Standard Detonator (NSD) used for all detonating functions on the Space Shuttle. The NSD is a combined NASA Standard Initiator (NSI) with a hermetically sealed Detonating Module. Hi-Shear detonators are designed to transfer shock waves and high pressure energies for initiating detonating trains, Shielded Mild Detonating Cord (SMDC) Flexible Confined Detonating Cord (FCDC) and other linear explosive lines. The PD Series function with 99.99% reliability at 95% confidence level from −165°F to +225°F and at altitudes to 420,000 feet. The PD series meet Range Safety Standards for RF & EMI hazards, and 5 minutes 1 Amp / 1 Watt No-Fire test.

Applications:

Applications:

Extreme low shock output Non-Explosive Separation Nut. These nuts are actuated by miniature electric motor on low energy with large bolt insertion tolerance.

These nuts are used in:

Cutters designed for robustness are used in deep space as well as deep submergence applications.

Used for rapid severance of:

Thrusters range from miniature type measuring less than ¼ inch diameter & 1 inch long to over 2 inch diameter and 9½ inches long. These devices are capable of exerting forces from less than 1 pound to more than 12,000 pounds.

Applications:

ESAFD provides dual explosive output for remote safing/arming and subsequent initiation of ordnance items. The Hi-Shear SAD505 is fully qualified for system use, target drone applications. The approximate weight is 2.9 pounds.

Features:

EBW initiators & detonators are used with our EBW firing units and cable assemblies.

These devices typically actuate:

LID & LI Laser detonators & laser initiators are used with our Laser Firing Units and Fiber Optic Cable Assemblies.

These devices actuate:

Flash-tube pumped laser rod systems use high power light to initiate LID and LI.

The laser firing unit features:

EFI is similar to EBW except that an exploding foil bridge is used to accelerate a flyer down the barrel to impact an insensitive secondary explosive.

Features:

Analog (electronic) recovery sequencer is part of the Advanced Concept Ejection Seat (ACES II) that time sequences aircrew ejection during a flight emergency.

The sequencer events are:

Acoustic Firing Device is part of essentially non-magnetic equipment used in the proximity of magnetic influence ordnance. It provides US Navy divers with a safe firing system for underwater demolition operations.

Magnetic influenced ordnance include:
