2129260-2 Connectors, Interconnects

D-Shaped Connectors - Centronics

The 2129260-2 D-shapes connectors, or commonly known as Centronics connectors, are a type of electrical connector widely used in the computer industry due to its reliability, small size and low cost. Fused with a rugged design and stability, these connectors are suitable for a wide range of applications. In this article, we will discuss the application field and working principles of 2129260-2 Centronics connectors.

Application Field

2129260-2 Centronics connectors are used in a variety of applications, such as connecting computers and peripheral devices, linking network to communication networks, data and voice line communications and connecting industrial automation devices. These versatile connectors are found in many peripheral devices, such as printers, scanners, routers, modems, and cameras, as well as being used in multiple computers. These connectors are also used in industrial machines to join sensors and actuators to the control panel.

Working Principle

The 2129260-2 Centronics connectors are designed to provide quick and reliable data communication. These connectors are based on the IEEE-1284 standard, which specifies the electrical and mechanical requirements for the connection between computers and peripheral devices. The connectors are part of a device-to-device connection, and the pinouts and electrical properties of the device must be compatible, in order for the connection to work properly. At the physical level, the Centronics connectors are designed with two rows of 36 pin contacts. The signal transfer rate for this type of connection depends on the version of the cable used and can be up to the rate as high as 5Gbit/s.

Centronics connectors use a simple plug and socket system for their operation. The plug has 36 pins arranged in two rows of 18 pins each, while the socket features two sets of 18 contact holes. The plug has a flat bottom with the pins arranged along the sides. When the plug is inserted into the socket, the pins slide into the contact holes and make an electrical connection. The force of the pins against the contact area ensures a firm connection between the plug and the socket.

Centronics connectors also provide two other types of data transfer: mode type and unidirectional. Mode type is usually referred to as "data-strobe", and it involves the devices exchanging data simultaneously. Unidirectional is used for slower connections and involves the peripherals sending data one after the other. The different types of data transfers are specified by the manufacturer of the Centronics cable.

The 2129260-2 Centronics connectors are widely used in the computer industry due to their reliable and low-cost design. These versatile connectors are suitable for a wide range of applications and provide quick and reliable data transmission. With their rugged design and stability, these connectors are an ideal choice for connecting computers and peripheral devices.
