The Miga T220 Memory Wire actuator provides 0.22" of stroke with nearly 3 pounds of force using 0.012" diameter High Temperature two-way trained Shape Memory Alloy wires.
The T220 is a volume-ready SMA wire actuator, with MOSFET switching & protection circuitry directly onboard the PCB: allowing for a simple 3-wire interface. Designed as an emergency 'initiator' for oxygen delivery systems, the ideal uses are as latch- or trigger- release mechanisms for battery-powered devices.
The T220 provides a stroke of 0.22" (5.6mm) and up to 3.0 pounds of force, but weighs less than 0.44 oz. (12.4 grams), providing a Force-to-Weight ratio of nearly 110:1. The overall envelope is 4.42 x 1.04 x 0.15”.
The T220 has a 3-wire interface: Voltage (+V), Enable (EN), and Ground (GD). The Enable voltage range is 2.5 volts to +V, but is typically a logic signal from a microprocessor. The actuator is energized whenever the Enable is raised ‘high’.
