Cable Release Mechanisms

Eaton's non-explosive actuator solutions include G&H TechnologyTM cable-release mechanisms. These low-shock devices can be configured with single or multiple release points and provide rapid releases with low power consumption. Additional features include:

  • 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.

Field Refurbishment Accelerates System-Level Testing

Cable releases utilize split-spool initiators as hold down preloading assemblies and cables as hold down release actuators.

Multiple-test sequences can be performed by field replacement of the initiators which typically costs less than 20% of the expense of replacing one shot, pyrotechnic devices.

Field-resetable mechanical initiators (right end of depicted solution) replace one of the electrical initiators to enable multiple test releases without the need for refurbishments.

Heritage Proven, Custom-Solution Capabilities

Eaton's cable release mechanisms have deployed solar panels and antenna arrays on multiple satellite programs. The heritage-proven technologies from these programs can be leveraged to quickly develop custom hold down and release mechanisms to support a wide range of mission requirements:

  • Single and redundant initiations for single and multiple cable releases.
  • Customer-defined load ratings and response times.
  • Form, fit, and function replacements for pyrotechnic actuators.
  • Integrated connector and cable assemblies.
