10250-55H3JL

D-Shaped Connectors - Centronics

The 10250-55H3JL is a D-shaped connector found in many computer peripherals such as printers, scanners, external hard drives, and modems. Though originally developed in 1970 by a company called Centronics, the connector is still widely used today. It has just 7 pins, and is perfect for transmitting parallel data (such as 8 bit ASCII characters) from a computer to a peripheral.

Type of D-Shaped Connector

The 10250-55H3JL is a type-B D-shaped connector. This is characterized by its two curved sides, and is the most common type found in existing computer peripherals. This type of connector can be further divided into different sizes, each specifically designed for different types of cables. The 10250-55H3JL is the smallest size, perfect for a thinner parallel data cable.

Application Field and Working Principle

The 10250-55H3JL is designed for short distances in parallel electronic connection transfer, often between a personal computer and a printer. It has 7 pins that correspond to the 7 parallel data lines, and is made of plastic shell and metal contacts. The contacts are designed for quick-connection and quick-release functions, which make it easy to plug in and remove from the peripheral device. As for its working principle, it allows the transmitting and receiving of data in parallel, which enables a much faster data transmission rate than a serial data connection.

Advantages and Disadvantages

The 10250-55H3JL offers many advantages, such as low cost, low power consumption, and small size. It is relatively simple and reliable, with a longer lifespan than some other types of connectors. It is also easy to connect and disconnect, making it perfect for temporary connections in printers and other computers peripheral. On the other hand, it can only transmit data in parallel, which limits its use in some applications that require serial data transmission.

Conclusion

The 10250-55H3JL is a type-B D-shaped connector, designed for short distance connection of parallel data stream. It has 7 pins for the respective data lines and is commonly used in printers and other computer peripheral. Though it is not suitable for all applications, it offers a number of advantages such as low power consumption, easy connection and disconnect, and cost-effectiveness. The 10250-55H3JL is still a widely used connector type today.
