Tension Links


Eaton's non-explosive actuator solutions include G&H TechnologyTM tension links. These low-shock devices are used in restraint and release applications such as Marman clamps (V-bands). Additional features include:

  • Safe handling and deployment; non-explosive actuators do not require the explosive materials precautions associated with pyrotechnic actuators.
  • Rapid releases with low power consumption.
  • Quick turn custom solutions, including complete clamping mechanisms, are also available.

Tension Links are Electrically & Mechanically Redundant


Tension links function as clamp fasteners until redundant split-spool initiators release their actuator shafts to facilitate operation.

These heritage-proven devices are primarily designed for circular-clamp applications such as Marman and V-band clamps.

Standard load ratings are available up to 2000 pounds (8.9 kilonewtons). Custom capabilities include customer-defined load ratings.

Custom Solutions Include Complete Clamping Systems


Eaton's tension link heritage includes surface-to-air missile programs and spacecraft that has landed on Mars. Heritage-proven technologies and design platforms can be leveraged to accelerate the development of custom solutions that deliver mission-critical reliability and high-load ratings with compact-form factors.

An extensive array of custom solution features and design options includes:

  • Customer-defined load ratings and response times.
  • Complete V-band and Marman clamp mechanisms.
  • Form, fit, and function replacements for pyrotechnic actuators.
  • Integrated connector and cable assemblies.

Additional Tension Link Information


Release-mechanism selection and design-in information is provided in Eaton's Non-Explosive Actuators Design Guide and the Space and Launch Capabilities Brochure.

Non-Explosive Actuators Design Guide contents include:

  • Non-explosive and pyrotechnic actuator technology comparisons
  • Theories of operation for actuators, cell-bypass switches, and highly-integrated solutions such as interconnect releases and structural-separation systems.

Space and Launch Capabilities Brochure contents include:

  • Release mechanisms technologies, design platforms and custom-solution capabilities
  • Space-rated connector selection including NATC, cryogenic to 5000 degrees F. operating ranges and low-imparted-shock solutions.
  • Theories of operation for electrically and mechanically initiated umbilicals and in-flight disconnects.
