Coaxial Connectors (RF)

Coaxial connectors are a type of electrical connector, broadly used in electronic and radio frequency (RF) applications. They typically include a male and female connector that seals around a protruding center conductor. Coaxial connectors provide robust connections, as well as protection against noise, electromagnetic interference and safety/security issues.

1253111-1 Application Field and Working Principle

The 1253111-1 is a coaxial connector designed for Military and Aerospace applications. This connector uses a threaded coupling interface for a low out-of-roundness value and a high mating repeatability. The 1253111-1 is designed to reduce the effects of vibration and shock on the connector interface, thereby providing a robust and reliable connection. The 1253111-1 is constructed of a copper alloy and plated with nickel for additional corrosion resistance. This connector features a three-piece design with a male center conductor for signal transfer and a low and high profile female shells to provide a secure fit. The female shells are designed to accommodate a range of cable sizes while providing a snug fit.The 1253111-1 offers excellent shielding and attenuation to prevent interference from outside sources. The highly conductive interface of the 1253111-1 reduces leakage and electrical loss between components, providing high-quality signal integrity throughout the system. The 1253111-1 is available in three sizes: 2.4mm, 4.3mm, and 5.0mm. The connector can operate between -55°C and +125°C for a wide range of applications. The connector is RoHS compliant and is suitable for use in aerospace, medical, military and commercial applications. The 1253111-1 is easy to install and works with existing cabling systems. This connector is rated for up to 7GHz for high-bandwidth applications. The threaded design provides a secure connection whenever the connector is mated and unmated. The 1253111-1 is compatible with a range of RF connectors, including the N-series, TNC, and 7/16 series. In summary, the 1253111-1 is a high-performance coaxial connector offering robust connections, superior shielding, and attenuation. The three-piece design enables secure and reliable mating, while the threaded coupling interface provides low out-of-roundness values and a high mating repeatability. The broad temperature range makes the 1253111-1 suitable for a range of applications, from aerospace to medical applications.
