External linear actuator is a rotating leadscrew design that incorporates ball bearings and a stainless-steel leadscrew in the motor's rotor. Shaft-to-leadscrew couplers are not needed for the actuator, making it targeted for use in limited-space applications. Available frame sizes include 20-, 26-, 36-, and 46-mm diameters. Step increments include 0.001, 0.002, 0.004, and 0.008 inch per step. The actuator is for medical devices, instrumentation, small machinery, office equipment, and any applications where precise, controllable linear motion is required.
Last year at Hannover Fair, lots of people were talking about Industry 4.0. This is a concept that seems to have a different name in every region. I’ve been referring to it as the Industrial Internet of Things (IIoT), not to be confused with the plain old Internet of Things (IoT). Others refer to it as the Connected Industry, the smart factory concept, M2M, data extraction, and so on.
Some of the biggest self-assembled building blocks and structures made from engineered DNA have been developed by researchers at Harvard's Wyss Institute. The largest, a hexagonal prism, is one-tenth the size of an average bacterium.
