Miga S173-NC Muscle Wire Actuator

$25.95

The S173-NC is a volume-ready SMA wire actuator, identical to the S125-NC, but 'stretched' to provide an extra 0.048" of stroke. Like the S125-NC, the S173-NC does not have the MOSFET switching & protection circuitry on board. The ideal uses are as latch- or trigger- release mechanisms for battery-powered devices.

The S173-NC provides a stroke of 0.173" (4.39mm) and up to 2.0 pounds of force, but weighs less than 0.2 oz. (5.7 grams), providing a Force-to-Weight ratio of over 160:1. The overall envelope is 4.89 x 0.5 x 0.12” (124.2 x 12.5 x 3.2mm).

Because of the longer Nitinol wire length, the S173-NC can be ordered with either 0.008" or 0.010" diameter Miga Two-Way Shape Memory Wire.

The S173-NC has a 3-pin (0.1") connector with Voltage (+V), End Switch (ESW), and Ground (GD). To protect the SMA wire from overheating, power should be cut the moment the End Switch (contact) is reached. The operating voltage range is 2.5 to 12 volts.

We recommend using a Miga MADv5 or similar circuit in conjunction with this actuator, or using a microprocessor to provide the safety features of the MOSFET power monitoring circuitry.
