Rectangular Connectors - Headers, Receptacles, Female Sockets

Rectangular connectors, sometimes also referred to as "headers", "receptacles" or "female sockets", provide a two-way connector system for electrical devices situated within the same circuit board or between separate boards. 89891-408H is a type of rectangular connector which is widely used for many applications.

The 89891-408H includes 4 sections which consist of different size and shape pins. The pins on the 89891-408H are divided into two separate sections with male and female pins from top and bottom, respectively. As mentioned earlier, the 89891-408H has four sections. The two sections closest to the ends are Male Pin Sections which have 8 male pins of 1.25mm widths and 1mm pitch with a flat top-angled surface. The two other sections are Female Sockets Sections which have flat-angled sockets facing outward. In between the male and female sections, are two plated plastic housings which provide the electrical connection and ensure the correct seating of the pins.

89891-408H connectors have a wide range of applications. The standard sizes make it suitable to link daughter boards, backplanes, PCB’s and cables. It can also be used in cases where an environment with low vibration or shock is required as their design includes two plastic housings that securely hold the connectors in place. 89891-408H connectors are most widely used in electrical boards for industrial machines, computers, cell phones, medical equipment, automobiles and other portable devices.

The working principle of the 89891-408H connector is simple. The male pins are inserted into the female sockets with the plastic housings in between. The contact between the pins and sockets is provided by the housed plastics. The plastic housing ensures that the contact occurs only when the two parts are connected properly and securely. Once properly secured, the contact point can carry signals and power to the desired devices.

In conclusion, 89891-408H connectors are widely used in various applications. The two plastic housings between the male and female openings ensure that the connection is secure and reliable. The 89891-408H provides a convenient solution to connect electrical devices together and provide an effective medium for signals and power to flow between the connected systems.
