Non-Explosive Separation Nut/Release Mechanism PRODUCT TECHNICAL DATA SHEET APPLICATION: Typical applications include: • Antennas • Scientific instruments • Solar arrays • Reflectors • Satellite, spacecraft and payloads • Booms and masts • Launch locks for gimbles, nozzles and thrusters PROPERTIES: DESCRIPTION: NEA ® Electronics, Inc. (NEA) designs a variety of Non-Explosive Separation Nuts/Release Mechanisms for a wide range of requirements, allowing customers to select specific nut size, redundancy and materials without affecting firing characteristics. Our products can support a static load of up to 100,000 pounds (approx. 45,000 kgs). NEA’s Non-Explosive Separation Nuts/Release Mechanisms are electromechanical and based upon patented split-spool and fuse wire technologies. The principle of operation involves a tensile load reacting against a wire-wound split-spool. Upon electrical command, a fuse wire breaks in tension and the restraining wire unwinds, allowing the spools to separate and release the load. Structurally robust, NEA’s Non-Explosive Separation Nuts/Release Mechanisms quickly and reliably release stored strain energy.

NEA® Electronics, Inc. (NEA) designs a variety of Non-Explosive Separation Nuts/Release
Mechanisms for a wide range of requirements, allowing customers to select specific nut
size, redundancy and materials without affecting firing characteristics. Our products can
support a static load of up to 100,000 pounds (approx. 45,000 kgs).
NEA’s Non-Explosive Separation Nuts/Release Mechanisms are electromechanical and
based upon patented split-spool and fuse wire technologies. The principle of operation
involves a tensile load reacting against a wire-wound split-spool.
Upon electrical command, a fuse wire breaks in tension and
