Left: 20-way grey ribbon cable with wire for pin 1 marked red, insulation partly stripped. Right: 16-way rainbow ribbon with IDC connector. IDC D-sub connectors DE-9 (male) and DA-15 (female) Twisted ribbon cable used for Parallel SCSI connections. A ribbon cable is a cable with many conducting wires running parallel to each other on the same ...
A 300-to-75 Ω balun, showing twin lead ribbon cable on the right hand side. Twin lead (in the specific sense of ribbon cable) is a form of parallel wire balanced transmission line. The separation between the two wires in twin-lead is small compared to the wavelength of the radio frequency (RF) signal carried on the wire.
Speaker wire is a passive electrical component described by its electrical impedance, Z.The impedance can be broken up into three properties which determine its performance: the real part of the impedance, or the resistance, and the imaginary component of the impedance: capacitance or inductance.
All speaker drivers have a means of electrically inducing back-and-forth motion. Typically there is a tightly wound coil of insulated wire (known as a voice coil) attached to the neck of the driver's cone. In a ribbon speaker, the voice coil may be printed or bonded onto a sheet of very thin paper, aluminum, fiberglass or plastic.
Voice coils wound with flattened wire, called ribbon-wire, provide a higher packing density in the magnetic gap than coils with round wire. Some coils are made with surface-sealed bobbin and collar materials so they may be immersed in a ferrofluid which assists in cooling the coil, by conducting heat away from the coil and into the magnet ...
Twisted ribbon cable used for Parallel SCSI connections. A twisted ribbon cable is a variant of standard ribbon cable in which adjacent pairs of conductors are bonded and twisted together. The twisted pairs are then lightly bonded to each other in a ribbon format.
