TiNi’s Ejector Release Mechanism (ERM) is a uniquely simple and effective device which offers both high load holding capability and fast actuation time. The Actuator “Coupler” acts as a detachable Nut and may be used to support and release loads up to 4000 lbf.
ERM FAMILY OF PRODUCTS OFFERS THE FOLLOWING ADVANTAGES:
Flight Qualified – The ERM is a derivative of TiNi’s Pinpuller product line and was first flight qualified in March of 2001.
NEA (Non-Explosive Actuators) – As with all TiNi products, the ERM is non-pyrotechnic and field reset-able with a minimum qualified life of 50 cycles.
Field Reset-able and Reliable – The ERM can be reset within seconds while still attached to the structure via a simple tool provided by TiNi Aerospace.
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 – All TiNi ERMs 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 TiNi Trigger. This makes them very “user friendly” and operable from a wide range of current and voltages.
Misalignment Protection – All ERMs have a swivel feature such that the Actuator can rotate +/-5 degrees within its mounting enclosure. This is an important feature which protects against binding due to possible misalignment, and or instances where the deployable traverses an arc after release (such as in hinged assemblies).
