D-Shaped Connectors - Centronics

The 71661-5040 is a special type of D-shaped connector specifically designed to connect two peripheral devices, usually one output device such as a printer and one input device such as a computer. This type of connection is commonly referred to as a Centronics connection.

Application Field

Centronics connectors are widely used for connecting peripheral devices to computers in office settings, such as printers and scanners. They are also popularly used in consumer applications, such as connecting external hard drives and flash drives to computers.

Moreover, Centronics connectors are also used in industrial applications, such as factory floor automation and robotics. They serve as the main connection for robotic arms, motor controllers, and other machinery components.

Working Principle

Centronics connectors work by carrying electrical signals through a series of contacts on the connector. There are typically 36 contacts in total, with 18 individual contact pins on each side of the connector.

Each contact is responsible for carrying a separate signal, such as for transmitting or receiving data. This allows for very high speed data transfer between two compatible devices.

The contacts are attached to a metal body, which provides an electrical linkage between the two sides of the connector. The metal body also acts as a shield for the contact pins, preventing damage to them from physical impacts or electric shocks.
