These tension springs, when cool, can be extended or deformed to approximately 14 cm, using about 6N. When heated, they contract to about 29 mm overall, using approximately 8.4N, with 3 Amps. The 750 µm wire diameter, activates at about 55°C - 85°C. This is a demonstration product and the force and amperage values may vary.
Four pieces per pack. Use several in series for greater distance, or in parallel for greater force. Sold in a 4-Pack. Force will vary based on your application.
