Memory Metal Actuator - Dash4

Shape Memory metals, initially developed by NASA for the space industry, are now finding more and more uses on Earth. For instance, there are some studies on using these materials in robotics, which makes it possible to build very lightweight robots. The Dash4 memory metal actuator offers a stroke of 0.23 inches and over 1.75 pounds of actuation force. With a built - in limit switch, it can operate safely over a wide voltage range (and thus actuation speed) when used with the MAD - v5 (sold separately). It's just under an inch wide and less than 0.1 inches thick. Applications include automotive uses like bi - directional grill louver mechanisms, fuel tank door release mechanisms, and trunk/glove compartment release mechanisms. In the consumer field, it can be used as a memory card ejector, electronic latch release, for security doors and locks, and biometric sensor assist. For hobby or miscellaneous purposes, it can serve as a grasping device, be part of an undersea core sampling robot, for point - of - use sale items, latch release for ROVs, and as a pneumatic actuator replacement. Specifications: Stroke is 0.23 inches (5.8mm), output force is a constant 1.75 lb - f, actuation time to position - hold is 50 ms, 7V actuation needs about 2.1 amps, resistance is 3.2 ohms, it has holes for 2x 2 - 56 screws for mounting, an electrical interface of a 3P header on 0.1 inches pitch, operating temperature ranges from - 29 to 60°C, size is 68x38x3mm (2.68x1.50x0.12 inches), and it weighs 0.35 ounces (10g). Available documents are the Dash4 Datasheet and Application Notes. The shipping list includes one Dash4 Shape Memory Metal Actuator.

Using the Dash4 Shape Memory Metal Actuator is quite straightforward. First, make sure to use it with the MAD - v5 if you want to take advantage of its wide - voltage safe operation. Just connect it through the 3P header on 0.1 inches pitch as described in the specifications. When installing, use the holes for 2x 2 - 56 screws for a secure mount. For different applications like automotive or consumer uses, follow the relevant application notes. Note that the actuator has an operating temperature range from - 29 to 60°C, so don't use it outside this range to avoid damage. Also, be careful with the electrical connections to prevent short - circuits. For maintenance, keep it clean and dry. If you notice any abnormal behavior like changes in actuation force or time, refer to the Dash4 Datasheet or Application Notes for troubleshooting.
