Introduction

Centronics connectors are widely used in data communication and computer networks. It is the interface between the computer and the line, allowing the computer to communicate with peripheral devices. In order to meet the requirements of different applications, the connector has developed several series, such as UL68 and 84487-2 series. The 84487-2 series is a new generation of products made of plastic and metal material. This series of connectors are D-shaped, and can be used in a wide range of applications. After introducing the application field and working principle of 84487-2 series, the product selection can be made more accurately.

Application Field

The 84487-2 series connectors are widely used in networking and communication equipment. In this series, there are several foot options, such as 2.54mm, 3.96mm, 4.8mm, 5.08mm, and 6.35mm. In addition, in order to meet the demands of different customers, there are many compatible products, such as industrial computers, medical equipment, aerospace, automotive and audio equipment. It is used to connect various devices such as monitor, hard disk, microcomputer and communication equipment. At the same time, it can also be used in combination with other types of connectors, such as RJ45 connectors, to create a variety of data transmission systems.

Working Principle

This series of connectors mainly connects the signal line in and out, so how does it work? It is a "D" shaped interrupt structure, with two rows of pins inside. The first row consists of 36 pins with a pitch of 2.54mm, and the second row is 24 pins with a pitch of 3.96mm. There is a contact strip behind these two rows of pins, which correspond to the contact part of the two rows of pins respectively. When the two parts are connected together, the contact pins of the first row and the contact strips of the second row can touch and make electrical connection.

In addition, the 84487-2 series connectors are equipped with a stuffing box. The stuffing box is used to prevent dust and moisture from entering the connector, and protect the conductor contact from corrosion. The stuffing box is made of a special material or rubber, which can provide insulation and heat resistance.

Summary

To sum up, the 84487-2 series is a kind of Centronics connectors, which are commonly used in industrial computers, medical equipment, aerospace, automotive and other fields. They are generally "D" shaped, and the two rows of pins have 2.54mm and 3.96mm pitch respectively. The connectors are also equipped with a stuffing box to ensure insulation and prevent dust and moisture from entering. The 84487-2 series is suitable for a wide range of applications, and you can choose the appropriate product according to your needs.
