TiNi™ Subsea Pin Puller
EBAD Subsea Pin Pullers have been used in many oceanic projects. Typical applications include deployment of ballasts, buoys, cables, and other items from a wide array of AUVs. Much like our ERMs they include a Pressure Balanced and Oil Filled (PBOF) enclosure such that they can be used directly in sea water at high pressure.
NEA (Non-Explosive Actuators) – As with all EBAD products, the Pinpuller is non-pyrotechnic and field reset-able with a minimum qualified life of 50 cycles.
Rated to High Pressure – All Subsea Pinpullers incorporate a PBOF enclosure such that they can be used directly in sea water. All materials used have been selected to minimize corrosion and need for shipboard maintenance.
Field Reset-able and Reliable – The Pinpuller can be reset within seconds while still attached to the structure via a simple tool provided by EBAD.
Redundant Firing Circuit – As with all EBAD Actuators a redundant SMA circuit is incorporated. This provides complete electrical redundancy as well as mechanical redundancy for the critical trigger element.
Fast Acting – All EBAD Pinpullers can be actuated with a standard pyro pulse of only 25 milliseconds or less.
Auto Shut-Off Switches – Simple Auto Shut Off Switches are incorporated into each ERM to protect the Trigger. This makes them very “user friendly” and operable from a wide range of current and voltages.
Pin Puller Options
The P50 size Pin Puller retracts the output pin with 50 lbF (222 N) of force, in a matter of milli-seconds. It is capable of supporting applied side loads up to 490 lbF (2,180 N) during transport and deployment. As with all EBAD TiNi products, key attributes include:
Features:
-
- Non Pyrotechnic and Field Reset-able
- Redundant Firing Circuit,
- Maximum Reliability Thru
- Design Simplicity
- Pedigree, and
- Testability

Reset Tools
All EBAD 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.
