The Sierra Space PP-35055 Pin Puller is a remotely resettable mechanism that provides high retraction force.
The heart of the PP-35055 is an EH-35055 high force High Output Paraffin (HOP) actuator providing a maximum of 350 lbf of retraction force to the output pin.
The pin puller is fully resettable and contains an integral binary latching mechanism to provide high-shear and high retraction force.
When energized, the pin is retracted and then latched in the retracted position. When re-energized, the mechanism unlatches and the pin extends.
Appropriate applications include caging of gimbaled instruments, the release of high loads, and the restraint of rotating hardware.
This hermetic bellows-type seal actuator is coupled to a binary latch that toggles the mechanism between the two latched conditions (extended and retracted) when repeatedly operated.
Single or redundant limit switches for both extended and retracted conditions provide position telemetry.
