Separation nuts

Hold down and release actuators

Eaton's non-explosive actuator solutions include G&H Technology separation nuts. These restraint and release devices utilize redundant, split-spool initiators to provide rapid releases with low power consumption.

Overview Support

Core features

Safe handling and deployment; non-explosive actuators do not require the explosive materials precautions associated with pyrotechnic actuators.
Fragment and debris-free operation.
Form, fit, and function replacements for pyrotechnic actuators can be quickly developed.

Rapid releases across a wide range of operating temperatures

Separation nuts are available with standard load ratings from 4500 to 9500 pounds (20 to 42.2 kilonewtons). Customer-defined load ratings and attachment-bolt sizes are also available.

Separation nuts utilize split-spool initiators as hold down preloading assemblies and 1/4 or 5/16 inch load attachment bolts as hold down release actuators. After electrical initiation, load deployment is facilitated by threaded-segment release of the load-attachment bolt.

Heritage proven, custom-solution capabilities

Separation nut program heritage includes applications that extend from low-earth orbits to landings on Mars. The technologies used in these critical applications can be leveraged to accelerate the development of custom release mechanisms to support a wide range of mission requirements:

Customer-defined load ratings and response times.
Single or redundant initiation.
Cryogenic ratings, nickel platings, and a wide range of mounting configurations.
Form, fit, and function replacements for pyrotechnic actuators.
Integrated connector and cable assemblies.

Field reset & refurbishment capabilities

Field refurbishment is accomplished by replacing the expended initiators. Refurbishment costs are typically less than 20% of the cost of replacing one shot, pyrotechnic devices.

The refurbishment process can be performed in less than ten minutes.
Additional cost savings during testing are attained by eliminating the safety-assurance requirements inherent to firing pyrotechnic actuators.

Multiple-test sequences can also be facilitated by replacing the split-spool initiators with the field resetable mechanical initiator pictured to the left.

Field resetting is accomplished in under five minutes with no parts replacements.
The mechanical initiator imparts less shock than pyrotechnic devices and reduces the potential of damaging sensitive equipment during testing.
