Description
SMA PCB Connector | End Launch | Brass Body
The ROSNOL SMA7H5C50-1520A/91 is a reverse polarity SMA jack designed for bulkhead mounting and PCB end launch applications. With a screw-lock coupling mechanism and a minimum of 500 mating cycles, it ensures long-term mechanical reliability. Operating from DC to 18 GHz with a VSWR of ≤1.25, it delivers consistent 50 Ω impedance, low insertion loss, and high insulation resistance for demanding RF environments.Constructed with a brass body and beryllium copper center contact, all components are finished with 3 µinch gold plating over 100 µinch non-magnetic nickel-phosphorus underplating. The insulator is made of PTFE, and a silicone rubber gasket is included for environmental sealing.
ROSNOL’s precision-engineered RF connectors offer a competitive alternative to products from leading manufacturers in Europe, the USA, and other global markets. All Rosnol RF components are precision-manufactured in ISO 9001-certified facilities, and are fully RoHS and REACH compliant, ensuring environmental safety and global regulatory alignment. Customization services for plating, materials, and mechanical design are available upon request.
