Type: Wire
Price: 9.76 - 32.09 (2 variants)

Wire contracts when heated and extends by itself when cooled, even without a pull-back mechanism.
Linear 2-way actuator wire for high-end robotics. This wire does not require a "spring-back" mechanism to return the wire to its martensite shape. Repeat strain training while cold will set a new cold shape for the wire, but it is best to leave it straight and use it with electricity to work like a "muscle". The use of a pull back spring is still advised for best results.

CHARACTERISTICS

Activation temp: 55°C

Diameter (mm): 0.5

Stroke: 5% contraction when heated

Pull Force (N): 29

Resistance (Ω/m): 5.1

Current (mA): 3900

Time (s): 1

Regular nitinol shape memory wire has 1-way memory characteristics. The wire takes on a predetermined shape when heated (e.g., straight), and then becomes soft and malleable when it cools. In contrast, the 2-way linear actuator wire remembers its martensite (cold) shape, which has been pre-programmed as straight. This allows the wire to be used without a spring-back in linear actuator applications.
