Description
BMA Jack (Female) | Slide-On | 2-Hole Panel Mount | Brass Body | Semi-Rigid, Semi-Flexible Coaxial Cable Compatible
The ROSNOL BMA2CBT50-0085A/91X is a BMA Jack (Female) RF connector featuring a straight 2-hole panel mount and slide-on coupling mechanism. Designed for crimp cable entry, it supports .085 type cables and is fully compatible with Semi-Rigid, Semi-Flexible, and Flexible coaxial cable assemblies. Operating from DC to 22 GHz, it delivers excellent RF performance with VSWR ≤1.14 up to 18 GHz and ≤1.25 from 18 to 22 GHz. The connector supports ≥5,000 mating cycles and offers reliable engagement and retention forces.Constructed with a brass body and beryllium copper center contact, both plated with 3 µinch gold over 80 µinch non-magnetic nickel-phosphorus underplating, the connector ensures superior conductivity and corrosion resistance. The housing is made of passivated stainless steel, and the insulator is PTFE. It offers RF leakage suppression of ≥(90–f(GHz)) dB when fully mated and handles up to 300 W at 3 GHz, making it ideal for high-frequency, high-power applications.
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.
