Rectangular connectors, such as 3-966658-1, are used when a user needs to connect multiple wiring harnesses and/or printed circuit boards. They can be used to quickly and reliably mate and provide electrical connections between two components. They provide the benefit of being able to quickly assemble and disassemble connections without the need for solder.
The 3-966658-1 is a type of rectangular header, mating with a male pin connector. It\'s a single-row connector and is available in multiple pin counts, including 20 and 40 pins. It has a .100” pitch with a current rating of 5.0 A, and the pins and receptacles are made of brass. The housing is comprised of a thermoplastic polyester blended UL 94V-0 flame retardant material which has good resistance to a wide variety of chemicals, oils, and fuels.
The 3-966658-1 is mostly used in audio and video equipment, industrial and telecommunications applications, and computer interconnection and peripheral interfaces. The 3-966658-1 headers are highly reliable, durable, and cost-effective, making them an ideal choice for many electronic designs.
The 3-966658-1 is designed to plug directly into a PCB footprint on a board, and the number of pins on the header will match the corresponding number of pins on the PCB connector. A male connector is available to mate with the header for situations where the mating surface does not have a connector footprint. The two components are then connected through a ribbon or wire cable.
To ensure that the connections between the header and the male connector stay secure, the header features a secure latching system. This locking mechanism works by pushing the male connector into the header, at which point it will be latched in place. The latch also provides additional vibration protection to ensure that connections remain secure once made.
The 3-966658-1 rectangular header, and its mate male connector, are capable of reliable and durable electrical connections. Its small size is beneficial in many electronic designs, and thanks to its secure latching system, it is capable of providing a lasting connection. As such, the 3-966658-1 headers are widely-used in a variety of applications.
