Deployable systems and mechanisms > GRHT03-0006 : GRIPPER M3 - 6/12V - Ultra Flat Shockless Hold Down Release Actuator
Key highlights
The Nimesis GRIPPER - Shockless Hold Down Release Actuator is a lightweight and compact actuator designed for space applications.
It is used as a solution for the locking/unlocking and release of space mechanisms. GRIPPER is compatible with a wide range of satellites and space systems.
Operating Principle: It releases a nut by spreading two jaws, allowing for a progressive release that unloads the tie-rod before fully releasing it.
Shock-Free Activation: GRIPPER generates no shock when activated, ensuring smooth operation.
Slimmest Design: Its dimensions make it the slimmest actuator available for preloads up to 1500N.
Materials: Utilizes two CN-250X alloy rods, making it effective over a temperature range of -120°C to +120°C.
Automatic Reset: GRIPPER is automatically resettable, allowing for reuse in-situ without any user intervention.
This actuator is designed for high precision and reliability, making it ideal for applications requiring minimal space and maximum efficiency.
