74221-001 is a type of rectangular connectors, which belong to the array, edge type, mezzanine (board-to-board) category. This type of connector is used in critical applications that require high reliability. They are typically used in the aerospace, automotive, and industrial markets.

The 74221-001 connector is a two-row, low-profile, composite card-edge connector system. It is designed with a unique "semi-staggered" feature, which provides a 4.0 mm pitch between 0.060 and 0.025 inch thick printed circuit boards. This design feature allows the connector to maintain a low profile, as well as providing increased durability in high-vibration applications.

The connector is manufactured using an insulation displacement contact technology, which eliminates the need for a separate insulation displacement or contact crimp tool. The contacts are made of a gold plated material, which provides excellent contact resistance and improved high-frequency performance. The connectors also have a unique low-profile contact design, which reduces the possibility of mishandling during the assembly process.

The 74221-001 connectors are designed for both single-ended and double-ended applications. They are available in three different versions: standard, right angle and high-density. The standard version is designed to be used with single-sided boards, while the right angle version is best suited for double-sided boards. The high-density version is optimized for high-density applications and is designed to be used with both single- and double-sided boards.

All versions of the 74221-001 connectors feature a double latch locking system, which ensures secure mating of the connectors. The lock is designed to prevent accidental unmating of the connector, as well as preventing mechanical damage to the contacts. The connector is rated for up to 3.0A per contact, with a maximum total current rating of 19.2A.

The working principle of the 74221-001 connector is relatively simple. The pins and sockets are held together by a locking mechanism. The locking mechanism is triggered when the two connectors are pushed together from opposite sides. This movement causes the pins and sockets to become aligned, which allows them to connect to each other and form an electrical connection.

The 74221-001 connector is a great choice for applications where high reliability is a priority. Its unique semi-staggered design, gold-plated contacts, low-profile contact design, double latch locking system, and rated current ratings make it a very reliable connector system for a variety of installations. It is easy to install and helps to reduce installation time. With its high reliability, it is an ideal choice for a variety of applications.
