TiNi™ 2-way Optical Shutter

High Load Holding Capability and Fast Actuation Time

The EBAD TiNi™ 2 Way Actuator is used as a generic means to push and pull an output Pin in opposite directions. This may be used for functions ranging from Optical Shutters which can Open and Close on demand, to Fail Safe Actuators that require input to enable (or disable) a mechanical system.

NEA (Non-Explosive Actuators) – As with all EBAD TiNi™ products, the Shutter is non-pyrotechnic and field reset-able with a minimum qualified life of 100 cycles.

Field Reset-able and Reliable – The Shutter is reset by simply re-cocking the gate that is used to cover the aperture.  This is accessed from the side of the Actuator and may be operated with a simple tool provided.

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, EBAD TiNi™ Shutters perform in millisecond time frame making them ideal for time sensitive applications that also require low power consumption.

Auto Shut-Off Switches – Simple Auto Shut Off Switches are incorporated into each Shutter to protect the Trigger.  This makes them very “user friendly” and operable from a wide range of current and voltages.

2- Way Optical Shutter Options


The SPS-4690 uses TiNi’s Shape Memory Alloy (SMA) trigger mechanism to control the shutter gate and open or close the aperture. It can be operated with as little as 0.6 Amps of current.
