BMMA Jack (Female) Bulkhead Connector | Snap-in Mount | Stainless Steel Body
The ROSNOL BMMA2EA50-EZ085A/9X is a high-frequency BMMA jack (female) bulkhead connector designed for precision RF and microwave applications up to 22 GHz. With a 50 Ω impedance, VSWR ≤ 1.35, and low insertion loss (≤ 0.1 × √F), it ensures stable signal transmission and excellent return loss performance. The slide-on coupling mechanism supports over 5000 mating cycles, enabling fast and reliable connections. Featuring a soldered cable entry and plug-in center contact, this connector is optimized for semi-rigid .085 cable assemblies requiring consistent electrical performance.
The center contact is manufactured from beryllium copper with gold plating over a non-magnetic nickel-phosphorus underplate, providing superior conductivity, low contact resistance, and excellent wear resistance. The stainless steel body with passivated finish offers strong mechanical durability and high corrosion resistance, making it suitable for demanding environments. PTFE dielectric ensures stable electrical insulation performance across wide temperature ranges.
This ROSNOL BMMA bulkhead connector is widely used in RF test and measurement systems, high-frequency communication infrastructure, aerospace and defense electronics, microwave modules, and precision instrumentation. ROSNOL’s precision-engineered RF connectors deliver a cost-effective and high-performance alternative to leading global brands. All components are manufactured in ISO 9001-certified facilities and comply with RoHS and REACH standards, with customization services available.
