TiNi’s Pinpullers are fast acting and suitable for a variety of Aerospace applications. Pin retraction is achieved by coupling the recovery characteristics of Shape Memory Alloys with TiNi’s patented trigger mechanism. Pinpuller pull force ranges from 5 to 1000 lbf with five standard sizes offered as COTS (Commercial Off the Shelf) items.
PINPULLER FAMILY OF PRODUCTS OFFERS THE FOLLOWING ADVANTAGES:
Flight Qualified – Since its outer space debut aboard the Mars Global Surveyor spacecraft in November 1996, the TiNi Pinpullers have been qualified and used on numerous other space applications.
NEA (Non-Explosive Actuators) – As with all TiNi products, the Pinpullers is non-pyrotechnic and field reset-able with a minimum qualified life of 100 cycles.
Field Reset-able and Reliable – The mechanism is reset by simply re-extending the output shaft or Pin which may be accessed from the front or rear of the Pinpuller.
Redundant Firing Circuit – As with all TiNi Actuators a redundant SMA circuit is incorporated. This provides complete electrical redundancy as well as mechanical redundancy for the critical TiNi trigger element.
Fast Acting – By directly passing current through the SMA element, the Pinpuller’s perform in millisecond time frame making them ideal for synchronized and simultaneous release of multiple tie-down payloads.
Auto Shut-Off Switches – Simple Auto Shut Off Switches are incorporated into each Pinpuller to protect the TiNi Trigger. This makes them very “user friendly” and operable from a wide range of current and voltages.
