New SMA and RP-SMA Feedthrough Connectors from CLIFF Electronics

Female-to-female feedthrough connectors providing fast and easy assembly.

 

 

CLIFF Electronics announce the latest addition to their popular range of feedthrough connectors. The new range of SMA and RP-SMA connectors are female-to-female keystone couplers providing fast and easy assembly with no soldering required to connect equipment to external signals.

 

RP-SMA female-to-female front-or-rear-mounting DualSLIM metal feedthrough socket CP30761M..

 

With a standard impedance of 50 Ω and a frequency range up to 18 GHz, they have a secure, low-loss, threaded connection making them ideal for applications including RF communication systems (Wi-Fi, LTE, GPS), telecom, broadcast, AV equipment, aerospace and defence electronics. They are suitable for microwave systems and antennas, RF signal routing and test equipment.

 

 

The new SMA and RP-SMA feedthrough connectors are gold-plated with a Teflon insulator, have an operating temperature range of −30 to +80 °C and are available in the industry-standard XLR-format or the narrow, SLIM/DualSLIM frames for equipment where panel space is at a premium. Both versions offer multiple frame and mounting options of plastic, metal or black metal, with either plain, countersunk or threaded mounting holes.

 

The SMA and RP-SMA connectors can be assembled in any of CLIFF’s rack panels upon request.
