New and compact Shape Memory alloy actuators enable new freedom when it comes to the design of aircraft fastening and latching mechanisms. TZ has developed two families of mechanisms — point fasteners and strip fastener families. To power these families, TZ has two configurations of actuators: linear and circular. Linear actuators are used in point and strip devices, while circular actuators are used in mechanisms that require a pin or a stud. Both actuator configurations can be engineered to fit into very low profile shapes and packaged into weather resistant devices.
