TiNi™ Micro Latch

Developed Specifically for “New Space” Applications

The EBAD TiNi™Micro Latch was developed specifically for “New Space” applications such as hold down and release of Cubesats. It is small in size, fast acting, and a cost effective way to support and release preloads up to 50 lbf.

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

Field Reset-able and Reliable – The Micro Latch is reset by simply pushing the Coupler Nut back onto the body of the Actuator. The detent mechanism automatically engages with the Coupler Nut allowing immediate testing.

Fast Acting – By directly passing current through the SMA element, EBAD Micro Latch performs in millisecond time frame making them ideal for instantaneous release applications.

12Vdc Bus Voltage – The Micro Latch is designed to operate from a 12 Volt bus voltage as commonly available for Cube Sat deployments.  The resistance can be readily changed to suit other voltages if needed.

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

Micro Latch Options

The ML50 Micro Latch is designed to release loads up to 50 lbf [222.4 N] and capable of supporting forces up to 100 lbf [445 N] during maximum launch conditions. Standard interface uses a 4-40 thread to attach a Bolt or Stud to the releasable Coupling Nut. As with all EBAD products, key attributes include:


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