SM-5 sets of coaxial connectors
SM type coaxial connector product is a kind of radio frequency coaxial connector with thread and locking mechanism, which is characterized by compact structure, reliable connection and good vibration resistance. It is widely used to connect radio frequency coaxial cables in radio frequency circuits such as post and telecommunications equipment, digital wiring devices, and radio instruments.
A screw-connected RF coaxial connector produced in accordance with the IEC60169-13 standard; commonly used in 75Ω impedance systems, with stable performance and low loss.
