Mini DIN-8
The mini-DIN connectors are a family of multi-pin electrical connectors used in a variety of applications. Mini-DIN is similar to the larger, older 13.2 mm diameter DIN connector. Design Mini-DIN connectors are in diameter and come in seven patterns, with the number of pins from three to nine. Each pattern is keyed in such a way that a plug with one pattern cannot be mated with any socket of another pattern. They are each drastically different from the other, with no simultaneously and directly overlapping similarities in (1) pin arrangement, (2) square key size and position, (3) circular shielding metal skirt notches and metallic additions: in this they differ from the nonstandard mini-DIN connectors which may have directly overlapping characteristics to each other or to the standard mini-DIN connectors. Notable usage Some notable examples of standard mini-DIN connectors include: * Mini-DIN-3 connectors were used in early implementations of Apple LocalTalk. * Mini-D ...

Keithley Instruments
Keithley Instruments is a measurement and instrument company headquartered in Solon, Ohio, that develops, manufactures, markets, and sells data acquisition products, as well as complete systems for high-volume production and assembly testing. In September, 2010, the company agreed to sell itself to the Danaher Corporation, a Washington, D.C.–based conglomerate, for $21.60 per share. It was soon merged with Tektronix, Inc, which had been acquired by Danaher in 2007, and now exists wholly as a brand of Tektronix. History Joseph F. Keithley founded Keithley Instrument in 1946. His first product, the "Phantom Repeater," amplified low-level electric signals so that they could be measured by more standard equipment. The device was used by physicists, chemists, and engineers in the development of hearing aids and amplifiers. The product enjoyed some success in sales, but it was the next product, an electrometer, that clinched the future for Keithley's fledgling company. Gener ...

DC Connector
A DC connector (or DC plug, for one common type) is an electrical connector that supplies direct current (DC) power. Compared to domestic AC power plugs and sockets, DC connectors have many more standard types that are not interchangeable. The dimensions and arrangement of DC connectors can be chosen to prevent accidental interconnection of incompatible sources and loads. Types vary from small coaxial connectors used to power portable electronic devices from AC adapters to connectors used for automotive accessories and for battery packs in portable equipment. Extra-low voltage (under 120 VDC) These extra-low voltage connectors are rated at or below 120 VDC. Cylindrical connectors Small cylindrical connectors come in various sizes. They may be known as "coaxial power connectors," "barrel connectors," "concentric barrel connectors," or "tip connectors." These plugs are intended for use on the cable connected to an external AC adapter (power supply). The matching ja ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Headquartered in Heilbronn, Germany, Beyerdynamic has been family-owned since its founding in 1924. In June 2025, Beyerdynamic announced plans for a sale to Chinese firm, ''Cosonic Intelligent''. History In the 1920s in Berlin, founder Eugen Beyer believed that cinema presented a new opportunity in communication media. The first products he produced were loudspeakers for film palaces in 1924. At the end of the 1930s, Beyer developed the first pair of dynamic headphones, the DT 48. World War II temporarily froze production; however, in 1948, Beyerdynamic sought new beginnings in Heilbronn. The "Stielhörer" DT 49 became a popular item of "Plattenbars" (record-bars) in the 1950s. Beyerdynamic developed the highly directional ribbon microphone Beyerdynamic M 160 model in 1957, along with the figure-8 pattern M 130. These mic ...

Programmable Logic Controller
A programmable logic controller (PLC) or programmable controller is an industrial computer that has been ruggedized and adapted for the control of manufacturing processes, such as assembly lines, machines, robotic devices, or any activity that requires high reliability, ease of programming, and process fault diagnosis. PLCs can range from small modular devices with tens of Input/output, inputs and outputs (I/O), in a housing integral with the processor, to large rack-mounted modular devices with thousands of I/O, and which are often networked to other PLC and SCADA systems. They can be designed for many arrangements of digital and analog I/O, extended temperature ranges, immunity to electrical noise, and resistance to vibration and impact. PLCs were first developed in the automobile manufacturing industry to provide flexible, rugged and easily programmable controllers to replace hard-wired relay logic systems. Dick Morley, who invented the first PLC, the Modicon 084, for Gene ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

S-Video 7-pin Quasi-DIN Connector
S-Video (also known as separate video, Y/C, and erroneously Super-Video) is an analog video signal format that carries standard-definition video, typically at 525 lines or 625 lines. It encodes video luma (video), luma and chrominance on two separate channels, achieving higher image quality than composite video which encodes all video information on one channel. It also eliminates several types of visual defects such as dot crawl which commonly occur with composite video. Although it is improved over composite video, S-Video has lower color resolution than YPbPr, component video, which is encoded over three channels. The Atari 8-bit computers, Atari 800 was the first to introduce separate Chroma/Luma output in late 1979. However, S-Video was not widely adopted until JVC's introduction of the S-VHS (Super-VHS) format in 1987, which is why it is sometimes incorrectly referred to as ''Super-Video''. The S-video format was widely adopted in consumer equipment due to its improvemen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

InPort
A bus mouse is a variety of IBM PC compatible, PC computer mouse which is attached to the computer using a specialized interface (originally, the Microsoft InPort interface developed for Microsoft's original mouse product). In the late 1980s, mice were not integrated with IBM-compatible personal computers, and the specialized bus interface (implemented via an Industry Standard Architecture, ISA add-in card) was one of two popular ways to connect a mouse; Serial port, serial interfaces were the other method. In addition to Microsoft, Logitech also made bus mouse interface cards. When the IBM PS/2 was introduced, it included a motherboard mouse interface which was integrated with the computer keyboard, keyboard controller (still called the PS/2 port, PS/2 mouse interface long after the PS/2 brand was withdrawn); this fairly quickly drove the bus mouse design out of the marketplace. The bus mouse lived on in the PC-9801, NEC PC-98 family of personal computers in Japan. Quadra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
