Rectangular Connectors - Headers, Receptacles, Female Sockets - have become increasingly popular for making industrial, commercial, and military connection with electrical and electronic components. Specifically, 89891-320 connectors are used for a number of different applications in a variety of industries. This article provides an overview of 89891-320 connectors and their application field and working principle.

89891-320 Connectors Overview

89891-320 rectangular connectors are a type of spring-loaded wire-to-board connectors that provide a 8 ways of connecting electrical components. Designed for high vibration applications, they are highly reliable and robust, with contact forces of up to 160PSI. The connectors are available in a variety of sizes including 0.8mm, 1.25mm, 2.00mm, and 3.50mm. Additionally, the connectors have a 10A current rating and an applicable voltage rating of up to 800V. This makes them suitable for both DC low voltage and AC high voltage applications. 89891-320 rectangular connectors also feature a low closed height profile of <2mm, allowing them to occupy minimal space on the board.

Application Field

89891-320 connectors are used for a wide range of applications in many different industries. They are particularly popular for mounting in industrial control panels, with a variety of sizes and contact forces available for specific types of application. Additionally, 89891-320 connectors are suitable for automotive, medical, and medical device uses, making them ideal for a broad range of design and environmental considerations. Finally, their high-voltage capabilities make them suitable for applications such as building light controls, environmental monitoring systems, security systems, industrial and commercial machines, and more.

Working Principle

The connectors are designed to provide a secure, low-resistance connection between two electrical components. Each contact has two parts: a housing and a contact piece. The contact piece has two spoon-shaped surfaces which carry the electrical current. The housing is typically made of an insulating material, such as polypropylene, ABS, or polyethylene, and serves as a barrier between the two contact pieces. The unique shape and large contact area of the contact piece ensures a low electrical resistance.

One contact piece is inserted into the groove of the other contact piece, allowing them to slide past each other. When both contact pieces are fully inserted, the contact force of the spring-loaded contact piece increases, locking the two pieces in place. This arrangement provides the secure connection required for high-vibration applications.

Conclusion

The 89891-320 connectors are a high-quality, highly reliable, and versatile type of spring-loaded wire-to-board rectangular connector with low closed-height profile. Featuring 10A current ratings and voltage ratings up to 800V, they are suitable for a range of industrial and automotive applications. The unique design of the contact piece ensures a secure and low-resistance connection between two electrical components. With a wide range of sizes and contact forces available, 89891-320 connectors provide the reliability and robustness required for a variety of applications.
