TiNi™ Pin Puller

Fast Acting for Many Aerospace Applications

The EBAD TiNi™ Pin Puller is fast acting and suitable for a variety of Aerospace applications. Pin retraction is achieved by coupling the recovery characteristics of Shape Memory Alloys with a patented trigger mechanism. Pin Puller pull force ranges from 5 to 1000 lbf with five standard sizes offered as COTS (Commercial Off the Shelf) items.


Flight Qualified – Since its outer space debut aboard the Mars Global Surveyor spacecraft in November 1996, the TiNi™ Pinpuller has been qualified and used on numerous other space applications.

NEA (Non-Explosive Actuators) – As with all the EBAD TiNi™ products, the Pinpullers are 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 EBAD TiNi™ Actuators a redundant SMA circuit is incorporated. This provides complete electrical redundancy as well as mechanical redundancy for the critical 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 Trigger.  This makes them very “user friendly” and operable from a wide range of current and voltages.

Pin Puller Accessories

Reset Tools

All EBAD TiNi™ standard Pin Pullers are rated for a life of a minimum 100 actuation and reset cycles. For continued testing, EBAD provides reset tools of various shapes and designs – A few of which are shown in the photo to the right.

Standard Pin Puller reset tools come in two basic designs – A manual “push-pull” type that can be used to reset Pin Pullers up to 10 lbf. (ie P10), and a jack screw type that is used to reset up to 1000 lbf. All are simple to use and can be readily customized to suit application constraints.
