D-Shaped, Centronics Cables
What are D-Shaped and Centronics Cables?
1) D-type Interface: It adopts a D-shaped metal/plastic shell design, and ensures the stability of the connection through the trapezoidal arrangement of pins. It is commonly found in the serial/parallel ports of computers, printers, and other devices.
2) Centronics Interface: A standard parallel interface type, originally developed by Centronics, widely used for data transmission between old printers and computers, with multi-pin parallel communication capabilities.
What are D-Shaped and Centronics Cables Used for?
It is mainly used for the physical connection of industrial equipment, data communication equipment, and peripherals, such as high-speed data transmission between printers and hosts, test instruments, and industrial control systems.
Some models support shielding design to reduce electromagnetic interference (EMI) and are suitable for high-noise environments.
How to Choose D-Shaped and Centronics Cables?
Main manufacturers include 3M, TE Connectivity, Hirose, etc., providing customized solutions with different pin counts (such as 36 pins and 50 pins), lengths, and shielding levels.
When selecting, attention should be paid to the impedance matching, signal integrity, and environmental adaptability (such as temperature resistance and vibration resistance) of the cable.
What are the Technology Trends of D-Shaped and Centronics Cables?
With the popularization of USB and network interfaces, the application scenarios of Centronics interfaces are gradually decreasing, but there is still a stable demand for specific industrial equipment, medical instruments, and maintenance of old systems.
