Miga S125-008 SMA Actuator


The S125 is a volume-ready SMA wire actuator, with MOSFET switching & protection circuitry directly onboard the PCB: allowing for a simple 3-wire interface. The ideal uses are as latch- or trigger- release mechanisms for battery-powered devices.

The S125 provides a stroke of 0.125" (3.2mm) and up to 2.0 pounds of force, but weighs less than 0.17 oz. (4.75 grams), providing a Force-to-Weight ratio of over 140:1. The overall envelope is 3.75 x 0.5 x 0.12” (95.25 x 12.5 x 3.18mm).

The S125 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’.
