Coaxial cable sizes describe the cable's outer diameter, impedance, and conductor geometry, which together determine power handling, signal loss, and flexibility. Common sizes range from micro-coax (OD < 2 mm) for compact electronics to large-diameter cables like RG-213 for. Properties for popular coaxial cables are listed below including Type, Z0, Dielectric, Capacitance, dB. Details and definitions of the important specifications and parameters used to define the performance of the different types of RF coaxial cable and feeder. Each cable type presents a distinct combination of electrical, mechanical, and handling characteristics, requiring engineers to navigate key trade-offs. The following cable guide lists standard flexible, Low Loss, semi-rigid and conformable, micro-coaxial and corrugated cable as well as associated product links.
[pdf] The motor with optical control uses a flat opaque disk with four blades attached to the rotor. If you're interested in the field of robotics and computer vision systems, you've likely heard of optic flow sensors. But what exactly are they, and how are they used. PMW3901 is an optical flow ASIC that computes the flow internally and provides a difference in pixels between each frame. It uses a tracking sensor that is similar to what you would find in a computer mouse, but adapted to work between 80 mm and infinity. It can be used to determine speed when navigating without GNSS — in buildings, underground, or in any other GNSS-denied environment.
