Rectangular Connectors - Headers, Receptacles, Female Sockets

89891-348H Application Field and Working Principle

The 89891-348H connector is part of a large family of rectangular connectors which are used in a wide variety of applications, ranging from industrial to consumer electronics. Typically consisting of a male and female pair, connectors such as the 89891-348H can act as a bridge to repair existing connections, form new connections or provide an electrical signal. In this article we will look at the 89891-348H connector and how it is used.The 89891-348H connector is a two-piece connector, with male and female components which fit together to form an electrical connection. The male connector is a Header, which consists of a pin inserted into a plastic housing, with a metal tongue wrapping around the back. The female component is a receptacle, which is generally made from a metal shell with an insulating plastic liner. The metal tongue of the Header plugs into the receptacle, making contact with the metal shell inside which is electrically connected to the other end of the connection.The 89891-348H connector features two main functions. Firstly, it is used in applications which require a low electrical impedance connection. This is due to the low contact resistance between the male and female components, meaning that the connection is very low in resistance, resulting in a low impedance connection. This can be used in applications such as converters, switches and relays, where a low impedance connection is important to reduce interference. The second major function of the 89891-348H is as a digital signal in/out connection. This is due to the form factor, wherein the Header and Receptacle can both be easily modified to take digital signals in and out. This is popular in the robotics and automation industries to send small digital signals between components such as sensors, actuators, processors and motors. In summary, the 89891-348H connector is part of a large family of rectangular connectors which are suited for a wide range of applications. It is a two-piece system consisting of a male Header and female Receptacle, which is used as a low impedance connection or digital signal I/O connection.
