Circular Connectors - Contacts: 46740ST9 Application Field and Working Principle

Circular connectors with contacts, also known as electrical connectors, are components that are used to join electrical and electronic circuits, allowing them to transmit power and signals safely. The 46740ST9 is a surface-mount circular connector contact suitable for automotive, military, and aerospace applications. This article looks at the applications and working principle of the 46740ST9.

Applications

The 46740ST9 surface-mount contact is designed to be incorporated into a variety of electrical and electronic applications. Such applications include:• Automotive wiring harnesses, where it can be used to connect sensors, switches, and other electronic components.• Military usage, for relays, switches, and connections in harsh environments.• Aerospace applications which require high-performance connections in cramped spaces. • Telecommunications, providing secure connections between voice and data signals.• Industrial, process control, and instrumentation equipment.

Working Principle

The simple yet efficient design of the 46740ST9 makes it popular for many kinds of electrical and electronic applications. It consists of a contact pin that is mounted on the outside of the connector body. The contact is secured to the body using an insulated crimp sleeve or a threaded joint. The contact pin is made from a gold-plated beryllium-copper (BeCu) spring clip, which provides excellent conductivity. The spring clip ensures a consistent contact pressure between the connector and the mating housing. The contact opens when the spring is compressed, making it easy to insert, remove, and replace without damage. The housing of the 46740ST9 connector contact is made from UL-94 V-0 rated resin, which makes it highly durable and corrosion resistant. This resilient material is also designed to be compatible with electrical tapes and other methods of insulation.

Conclusion

The 46740ST9 contact is an ideal solution for many applications in automotive, military, aerospace, telecommunications, instrumentation, and industrial environments. Its simple yet efficient design makes it easy to install and ensures reliable, low-loss connections. Its UL-94 V-0 rated housing also ensures that it is highly durable and corrosion-resistant.
