![]() ![]() The male is equipped with a hex nut measuring 5/16 inch (0.3125 inch/7.9mm). As a result, these cables are compatible with many of Thorlabs High-Speed Detectors. The SMA connector employs a 1/4 diameter, 36-thread-per-inch threaded barrel. The required torque is usually 8 inch pounds. The SMA connector can mate directly to a 2.92 mm, 3.5 mm, or K connector. They can be tightened to the correct tightness with a special torque wrench, so that a good connection can be achieved without over-tightening. The connector has a threaded external connection interface, which has a hexagonal shape and allows tightening with a wrench. Many microwave components include filters, attenuators, mixers and oscillators, using SMA connectors. It is commonly used to provide RF connections between circuit boards. It has found many applications to provide connections for RF components in devices that require coaxial connections. The SMA connector is a subminiature coaxial cable connector whose name comes from the Sub-M iniature A connector. The signal frequency range supported by SMA connectors is from DC to 18GHz, and some types can support up to 26.5GHz. The full name of SMA is SubMiniature version A, which was invented in the 1960s. They are often used for GPS clock interfaces on single boards and test ports of base station radio frequency modules on wireless equipment. SMA connectors are suitable for connecting radio frequency cables or microstrip lines in the radio frequency loops of microwave equipment and digital communication systems. A silver roller is included in the package for attachment/connection to the. Reverse Polaritry Connectors are designed for Spectrum wireless. The 24 carat gold plated SMA male connector has a internal thread and a spine. It has the characteristics of wide frequency bandwidth, excellent performance, high reliability and long life. SMA Male Left Hand Thread Reverse Polarity Connector RG58. It has a silicon rubber O-ring, which separates the main body and coupling nut for dust resistance.SMA connector is a widely used coaxial connector with small threaded connection.The female connector has a 4.32-mm-long thread for coupling.The male connector is equipped with a 5/16-inch hex nut to allow torque by a 1/2-inch wrench.It uses a 1/4-inch-36-thread-type coupling mechanism. The SMA connector familyutilizes a threaded coupling nut system for mating and de-mating.The fitting it is threaded onto should have a valve inside and an O ring to seal so no freon. Some mechanical features of the SMA connector include: Also end of frame Lighting Connector information provided. This was apparently done on purpose by the FCC to prevent home users from damaging sensitive RF equipment when screwing on the antenna. Long Thread RF Coaxial SMA Connector for PCB Mount, Find Details about RF Coaxial Connectors, RF Connectors from Long Thread RF Coaxial SMA Connector for. The latter is often placed on and attached to a stable device, whereas the former is located on the detachable wire attachment.Ī newer reverse-polarity SMA specification (RP-SMA or RSMA) reverses the polarity of the genders so that the female connector now has the center pin and the male connector has the center receptacle, but the threads and other features remain the same. 141 semi-rigid cable, but now produced for use with both flexible and semi-rigid cable from. The male connector is the one with the center pin and inside threads of size 1/4-inch-36, whereas the female connector is the sleeve counterpart that features an outside thread and is used to hold the connection in place. SMA SMA connectors are semi-precision 3 mm high frequency connectors, originally used with. The main features of this connector are its high mechanical strength and high durability, as evidenced by its robust-looking metal construction. SMA connectors from Pasternack are available in straight, radius right angle or right angle versions, as well as, press in, bulkhead, 2 hole panel, 4 hole panel or mountless options. The SMA connector is considered a semi-precision, sub-miniature and high-frequency connector that is rated to deliver reliable broadband performance from DC to 18 GHz, with a constant impedance of 50 ohms and low reflection. Our SMA connectors are constructed in male or female gender in standard polarity, reverse polarity (RPSMA / RP-SMA) or reverse thread threads, with 50 Ohm impedance.
