Shape memory metals, initially developed by NASA for the space industry, have found growing uses on Earth. For instance, they are being explored in robotics to create extremely lightweight robots. The NanoMuscle Rotary shape memory alloy actuators are tiny, silent, and super light, weighing just 4.2 grams. They offer 60° of rotation. A linear NM70 - Super memory metal actuator is encapsulated in a body with a spring - loaded, cam - action rotary output. There are two versions: the 2 - pin NM70R - 2P and the 6 - pin NM70R - 6P. The 2 - pin actuator bounces between limit stops when powered, while the 6 - pin provides better control with end - limit sensors and can be driven by the MADv5 (sold separately). Operating voltages range from about 3 - 9V. Check the Downloads page for more details. Applications span across various fields. In the automotive sector, it's used for bi - directional grill louver mechanisms, fuel tank door release mechanisms, and trunk/glove compartment release mechanisms. In consumer products, it can be found in memory card ejectors, electronic latch releases, security doors and locks, and biometric sensor assists. For hobby and miscellaneous uses, it serves as grasping devices, in undersea core sampling robots, point - of - use sale items, latch releases for ROVs, and as a replacement for pneumatic actuators. Specifications include operating voltages of 3 - 9V, up to 60 - degree rotation in either direction. The 2 - pin version offers direct on/off control. Simply apply 3 - 6V at 350mA to make the rotary turn. It measures 50x10x15mm (1.97x0.39x0.59') and weighs 4.2g. Available documents are NM70R - Pinouts, Miga documents, and a NanoMuscle NM70R - 2P Video. The shipping list includes one Memory Metal Actuator - NM70R(2P).
Using the NanoMuscle Rotary Shape Memory Alloy Actuator - NM70R (2P) is quite straightforward. First, connect it to a power source. For the 2 - pin version, when you supply power, it will start 'bouncing' between limit stops. You can use an operating voltage between 3 - 9V. To make the rotary turn, just apply 3 - 6V at 350mA. As for the 6 - pin version, it offers more control with end - limit sensors and can work with the MADv5 (which you need to buy separately). When using it in different applications like automotive or consumer products, make sure to follow the installation guides for that specific application. Regarding maintenance, keep it in a dry and clean place. Avoid exposing it to extreme temperatures as this might affect its performance. If you notice any abnormal behavior, refer to the available documents like the NM70R - Pinouts or Miga documents. Also, you can watch the NanoMuscle NM70R - 2P Video for a better understanding of its operation.
