Rectangular connectors, also referred to as headers, male pins, among other various names, are a type of connection which have many useful applications for a wide range of industries. In the 81020-520203 series, it’s important to know how these connectors are used and what the working principles are. To gain a better understanding of the 81020-520203, it’s important to look to at its primary applications and functions as well as gain a better understanding of the pieces and parts that make up the connector.

The 81020-520203 series is a type of multi-row connector system that is designed for the termination of both board-end and cable-end. It is primarily used in data, signal, and power applications with 2 to 13 poles. It is also designed to allow for “crimps-hold” which is the holding of a cable end in a straight position which helps to make the termination process easier and more secure. It is especially useful in many electronics and high-tech industries and can be found in many different applications like computers, both residential and industrial, telecommunications, navigation, automotive, and other similar applications. It is able to withstand typical environmental conditions such as a range of temperatures, shock, and vibration, and provides reliability in any type of harsh application. It has a full range of UL and CSA approved products which can also be special ordered if desired.

The working principles of the 81020-520203 series are similar to any other type of rectangular connector, the main components being some type of housing, a contact and a latch. The housing is the main part of the object that holds the others together and can come in various sizes and shapes. It provides strain relief, basic connectors it also has openings for fastening or mounting and shapes the object for a variety of connectors. The contact is typically some kind of metal or other material that provides a connection and is mounted to the center of the object. The latch is the part of the object that locks the contact in place and can be made of either metal or plastic, depending on the type of application. Each of these pieces works together to make a secure connection that will be reliable in most applications.

The 81020-520203 series are a type of rectangular connectors, also referred to as headers, male pins, that are primarily used in data, signal, and power applications and allow for “crimps-hold”. They are mainly used in industrial and electronics-related applications and have full UL and CSA approval. Working principles of the 81020-520203 series mainly involve a housing, a contact, and a latch, each of which work together to make a secure connection. With its multiple applications, and its reliable performance in harsh environments, the 81020-520203 series is one of the most versatile and dependable types of connectors.
