Hold down and release actuators

Tension releases - miniaturized

Eaton's non-explosive actuator solutions include G&H Technology miniaturized tension releases. These compact release mechanisms deliver a 250-pound (1.1 kilonewton) load rating while occupying less than one third of a cubic inch (five cm3). 

Caractéristiques principales

  • Extremely lightweight: < 12.5 grams (.44 ounces).
  • Safe handling and deployment; non-explosive actuators do not require the explosive materials precautions associated with pyrotechnic actuators.
  • Rapid releases with low power consumption.

Tension releases - miniaturized

Actuator bodies smaller than 1/3 cubic inch (5 cubic centimeters)

Miniaturized tension releases utilize split-spool initiators as hold down preloading assemblies and load shafts as hold down release actuators. After electrical initiation, load deployment is facilitated by internal release of the load-attachment shaft.

Miniaturized tension releases are available in standard load ratings up to 250 pounds (1.1 kilonewtons) and a separation stroke of 0.25 inches (6.3 mm). Customer-defined load ratings and separation-stroke lengths are also available.

Flight qualifications include night vision system detachment

Eaton's miniaturized tension releases have been qualified for use in critical applications such as separating night-vision goggles from a pilot’s helmet prior to emergency ejection. The technologies used in these ultra-compact devices can be leveraged to quickly develop custom hold down and release mechanisms for a broad range of applications:

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