Rectangular connectors are a type of electrical connector found in many applications. The familiar 451-80-256-00-017101 is a two-row, mirrored header configuration mating with male pins. This type of connector is typically used in system-level interconnects such as data buses, and commonly found in board-to-board, wire-to-board, cable-to-board, and mezzanine connections. It is a robust, reliable solution for many types of connections.
451-80-256-00-017101 rectangular headers feature two pairs of parallel rows of pins placed opposite of each other. To ensure proper connection, they come with a logical arrangement of pins spaced in different pitch options. The most common rows for this type of connector have four pins in each row, with arrangements such as two pins side-by-side or two parallel rows of three pins each. This connector design provides an exceptionally strong connector with high retention force and excellent mating capability. This makes it ideal for use in many applications that experience intense vibrations, shocks, or wide temperature ranges.
The basic construction of a 451-80-256-00-017101 is achieved by combining a stamped metal cover and a perforated metal tail shield. The cover acts as an insulator and eliminates the possibility of short circuits. The tail shield adds an additional layer of insulating material and support when the header is made in an environment with high humidity. This combination also helps to increase the connector’s current-carrying capacity and helps radiate heat away from the connectors.
In its basic form, a 451-80-256-00-017101 header is comprised of two sets of contacts, one male and one female. The male side includes the headers, pins, or terminal posts, which are held in place by solder. On the female side, the contacts are held in place by plastic clips. Together, these components properly distribute the current and voltage according to the design in the connector. The headers are typically inserted into a printed circuit board, and the pins or terminal posts also soldered into the board, completing the connection.
These headers on the 451-80-256-00-0171 form a connection between the two electrical components. In addition, the headers help to protect the components from environmental and mechanical stresses. The male and female contact arrangement eliminates or at least reduces the risk of damage to the components or connectors caused by vibration, shock, or water. The properties of the connector also reduce electrical noise and the risk of component failure or voltage drop.
The application of the 451-80-256-00-017101 header extends beyond connecting electrical components and boards. It is also used to hold switches, buttons, relays, and other types of control devices, and its size and shape makes it ideal for large-scale industrial equipment and lighting systems. The protective materials used in its construction help ensure the contact remains firmly connected, reducing the chance of abrasion on contact surfaces.
As the size and needs of a project increases, so does the need for more reliable and efficient connector systems. The 451-80-256-00-017101 header is a reliable and rugged option for a variety of applications, providing a secure and reliable connection without sacrificing signal integrity. Additionally, its size and shape is adaptable to a variety of environments, making it a great solution in applications that require a superior connection.
