Rectangular Connectors - Headers, Male Pins are part of a wide range of connectivity devices for wired electrical connectivity applications. Commonly used for connecting electronic components into a printed circuit board, these connectors are also used in industrial automation, medical equipment, communication and other similar applications. The 0901200778 is one of the most commonly used types of connectors within this category, with an insulation displacement connection technology for fast and reliable termination.The 0901200778 is a dual row, right angled header with a current rating of 3.0 A per contact. As the contacts are completely enclosed within an insulating housing, both insulating material and contacts are highly resistant to transient over-voltage and still guarantee secure mating with no contact bounce. This type of connector also has an extended contact surface area to provide more current carrying capacity and more reliable contact.In terms of construction, this rectangular connector is made from high quality polyester material and has a 1.27 mm horizontal spacing between pins that can be used as either solder or through hole technology. The contact pins are plated with gold for superior performance and are divided into three different types – male, female, and solder types.In terms of design, the 0901200778 offers a number of advantages. It has a single piece body design which is easier to mount on a circuit board and is also easier to assemble and inspect for quality control purposes. The connector also has an integrated positive locking feature which ensures a secure and reliable connection. This connector also has an offset positioning feature which helps minimize noise interference and ensures secure and reliable connections.Finally, the working principle of the 0901200778 is based on insulation displacement connection technology. This technology enables a low-cost, reliable connection between two terminals by cutting through the surface insulation on the conductor using a sharp, non-conductive pin. The process includes the stripping of the insulating layers on the conductive paths of the board and then introducing a sharp pin into the unmasked wire insulation. The sharp pin then pierces through the insulation and electrically joins the wire and the device being connected to it.In conclusion, the 0901200778 is a reliable, modular connector system that is widely used in electronic applications. It offers a variety of features including an extended contact surface area, dual row, right angled design, gold plated contacts, single piece body and positive locking connection mechanism. Additionally, it offers reliable connections through insulation displacement connection technology and can be easily mounted on circuit boards.
