SF9421-6001 Datasheet/PDFCoaxial Connectors (RF) - Contacts
A coaxial connector (RF) contact is a type of electrical connection found in many radio frequency (RF) applications. SF9421-6001 is one of the types of coaxial connectors. In this article, we will discuss the application field and working principle of the SF9421-6001.
Application Field of SF9421-6001
The SF9421-6001 is a miniature coaxial connector used mainly in portable and mobile radio equipment. It is considered one of the most popular miniature RF connectors currently. Its small sized housing provides a reliable connection for applications in places where space is limited. It also gives the required strength needed to resist everyday mechanical strength. It is commonly used in handheld radio systems and in-vehicle wireless communication.
Working Principle of SF9421-6001
The SF9421-6001 uses a center-pin contact that is grounded to the connector mating face. It consists of an inner conductive sleeve surrounded by an insulating sleeve. The inner sleeve provides the contact interface while the surrounding insulator seals out moisture and dust. The contact is able to provide excellent RF transmission characteristics, low insertion loss and high isolation. The primary purpose of the connector is to provide a reliable electrical connection and to reduce the signal losses between the contacts.
The SF9421-6001 is designed with a snap-on locking mechanism. This helps prevent any movement of the contact during installation and provides for an easy and reliable connection. The contact is terminated to the RF coaxial cable via the use of soldering. This process helps ensure a secure and reliable connection to the conductor.
Conclusion
The SF9421-6001 coaxial connector is a reliable, miniature RF connector used in many portable and mobile radio applications. It consists of an inner contact and an insulator surrounding the contact. The contact is terminated to the RF coaxial cable via soldering. The snap-on locking mechanism ensures a secure connection and helps prevent any movement of the contact during installation. With its small size and reliable connection, the SF9421-6001 is an essential component for many radio systems.
