2023-06-12 09:31:21

IO connectorinput/output connectoris an electrical interface used to establish a physical connection between a device or system and external devices or peripherals. It enables the transfer of data, signals, or power between different devices. These connectors are widely utilized in various products that necessitate data transfer or internet connectivity, including computers, routers, servers, and switches, as well as in applications where audio/video signal data input/output is required.


IO Connector types

Ethernet Connector

Ethernet connectors, such as RJ-45, are used to establish network connections between devices. RJ45 connectors can be used in various different applications that require an ethernet connection to a local area network (LAN). It is commonly used for wired internet connections, connecting devices like computer, routers, switches, and modems. The RJ45 connector is easy to terminate, compatible with Cat5e/Cat6/Cat7 Ethernet cables with high-speed data transmission at speeds of up to 1 Gbps.

USB (Universal Serial Bus), is one of the most popular I/O connectors used in keyboards, mice, printers, external storage devices, and more electronics, This connector enables the seamless transmission of both data and power through a single cable, making it exceptionally convenient, USB connectors support various data transfer speeds depending on the USB version and the device's capabilities. USB 2.0 transfer rates of up to 480 Mbps, USB 3.0 up to 5 Gbps, USB 3.1 Gen 2 speed up to 10 Gbps, and USB 3.2 can reach 20 Gbps or higher. USB ports can provide power to charge smartphones, tablets, and other USB-powered devices, eliminating the need for separate power adapters, and USB offer backward compatibility,


HDMI connector

HDMI (High-Definition Multimedia Interface), support the transmission of high-definition audio and video signals, allowing for the seamless playback of content in resolutions such as 1080p (Full HD), 4K Ultra HD, and even 8K Ultra HD. This enables users to experience exceptional picture and sound quality, just use a single cable, ensuring a lossless and reliable transmission of audio and video data., They are commonly used for connecting displays, televisions, and projectors to computers, gaming consoles, and media players.


D-Sub connector

D-sub(D-subminiature) connector is a type of I/O connector commonly used for various applications, available in different applications like computer interfaces (such as VGA and serial ports), industrial equipment, instrumentation, telecommunications, and video game consoles, They can carry signals such as video, audio, serial data, parallel data, and control signals. D-sub pin configurations, such as 9, 15, 25, 37, and 50 pins. The number of pins determines the specific application and functionality of the connector, additionally, connectors have metal shielding surrounding the pins, providing electromagnetic interference (EMI) protection and enhancing signal integrity.
