SEE HOW IT WORKS!

TiNi’s Auto Resetable Pinpullers were born out of space constrained applications where the Actuator is buried deep within a complex instrument with no access to perform a manual reset. Auto reset is achieved by incorporating a secondary SMA actuator which can re-extend the Pin and yet not interfere with normal actuation. This is done using a custom flexure developed by TiNi using our patented SCSMA material.

TiNi AUTO RESET-ABLE PINPULLERs OFFER THE FOLLOWING ADVANTAGES:

NEA (Non-Explosive Actuators) – As with all TiNi products, the Auto Resetable Pinpullers are non-pyrotechnic and field reset-able with a minimum qualified life of 100 cycles.

Electrical Reset – The mechanism can be reset remotely by powering the reset circuit with no manual intervention. A redundant reset circuit may be incorporated for maximum reliability.

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.

Auto-Reset Pinpuller Options

AUTO-RESET PINPULLER P5

The P5SR Auto Resetable Pinpuller retracts the output Pin with 5 lb (22N) of force. It uses the same TiNi trigger mechanisms as used in our P5 standard Pinpullers which have 20+ years of space pedigree. It is fast acting and qualified to endure typical Aerospace environments. As with all TiNi products, key attributes include:

Features:

  • Non Pyrotechnic and Field Reset-able
  • Redundant Firing Circuit,
  • Maximum Reliability Thru
    • Design Simplicity
    • Pedigree, and
    • Testability

Function Time at Various Temperatures
