IntroductionThe 146897-2 connector is part of the rectangular connectors family and is an edge, array, and mezzanine type. It is a popular rectangular connector for board-to-board applications. It is often found in industrial automation systems, automotive systems, and consumer grade telecommunications.Features & BenefitsThe 146897-2 connector features a two-row, keyed header layout. The rows are connected at a slight angle to improve the connection strength. The keyed design ensures the correct orientation of the connection. The connector is also designed with a floating design, which offers greater flexibility and reduces stress on the connection when the board is heated and cooled. Additionally, the floating design also eliminates the need for additional supports. The connector is designed with gold plated contacts for enhanced electrical performance and wear resistance. It has a corrosion-resistant aluminum body for increased durability and reliability. It is RoHS and UL certified for high-quality, safe operation. The connector is also IP67 rated for water and dust protection.ApplicationsThe 146897-2 connector is ideal for a wide range of applications. It is often used in industrial automation systems, automotive systems, and consumer grade telecommunications. It is also suitable for applications in medical equipment, automated test systems, military systems, motion control systems, and electrical and electronic equipment.Working PrincipleThe 146897-2 connector is designed with two rows of keyed contacts that are connected at an angle to create a strong connection. The keyed design ensures the correct orientation of the connection. The contacts are gold plated for enhanced electrical performance and wear resistance. The connector also features a floating design that eliminates the need for additional supports and helps reduce stress on the connection. The contacts are made of metal that is then plated with gold or silver to ensure a secure connection and good electrical and data transmission. The contacts are also made with spring-loaded pins to allow for easier mating and demating. When two boards are connected, the contacts in the 146897-2 connector create an electrical connection between the two boards. The contact pins are pressed together and the current is transferred from one board to the other board. Additionally, the connector can also provide good signal integrity and transmission for high speed data applications.ConclusionThe 146897-2 connector is a popular rectangular connector for board-to-board applications. It is an edge, array, and mezzanine type connector that is often found in industrial automation systems, automotive systems, and consumer grade telecommunications. It features a two-row, keyed header layout with gold plated contacts for enhanced electrical performance and wear resistance.
