Features

By converting the holding tension force to rotational motion of an inner rotor, it is possible to prolong the operating time to release (shock reduction).
Shape memory alloy is adopted as trigger mechanism.

  • Low shock level (200 Gsrs or less @ 10kN)
  • Reusable
  • Small and light weight
  • Easy-handled


Applications

For many types of hold-down and release mechanisms.

  • Solar array panels
  • Launch locks of antenna
  • Small satellite separation mechanisms
  • and so on
