High Performance K Male Stainless Steel RF Coax Connector for MF143A Cable Plug
Xi'an Elite Electronic's precision 2.92mm connectors feature a 50Ω
impedance and an outer diameter of just 2.92 mm. These
characteristics make them suitable for test and measurement
applications up to 40GHz, ensuring high levels of reliability and
repeatability performance. The 2.92mm connectors are
interchangeable with most 2.92mm, 3.5mm, SMA, and K-type
connectors.
The 2.92mm (K) connectors are RF/Microwave coaxial connectors
designed for operation up to 40GHz. They are compatible with SMA
and 3.5mm connectors, making them ideal for high-frequency module
applications and testing and measurement (T&M) scenarios.

Features:
Excellent Mechanical Performance: The use of stainless steel
provides these connectors with superb mechanical strength and
corrosion resistance. They are highly suitable for harsh
environments such as outdoor communication equipment, marine
exploration devices, and equipment used in high-temperature or
high-pressure environments. The use of stainless steel ensures that
the connectors maintain stability even when exposed long-term to
moisture, corrosive gases, or other harmful environments.
Application:
Electronic Products: The demand for miniaturized, high-performance
connectors is growing in modern household appliances and
entertainment electronics. K-type stainless steel cable connectors
are used in high-end audio systems, smart home devices, and virtual
reality headsets. These products have strict requirements for the
size and performance of connectors, which K-type connectors can
meet.
Automotive Applications: As the level of automotive electronics
continues to increase, so does the demand for connectors. K-type
stainless steel cable connectors, with their excellent mechanical
performance and ability to withstand environmental influences, are
widely used in advanced driver-assistance systems (ADAS),
in-vehicle infotainment systems, and electric vehicle battery
management systems. These applications require connectors that can
work stably under vibration, shock, and extreme temperature
conditions, which K-type connectors can provide.
