Description
BMA Plug (Male) | 2-Hole Panel Connector | Crimp Attachment | Stainless Steel Body
The ROSNOL BMA2EBT50-0085A/9X connector is engineered for high-frequency RF performance, supporting 50 Ω impedance and operating from DC to 18 GHz with VSWR ≤ 1.25 (≥19.08 dB return loss). Electrical specifications include insertion loss ≤ 0.05 × √F(GHz) dB, insulation resistance ≥ 5 GΩ, center contact resistance ≤ 2.0 mΩ, and outer contact resistance ≤ 2.0 mΩ. Rated for 1000 V rms test voltage and 400 V rms working voltage, this connector ensures reliable signal integrity for demanding microwave applications.Constructed for durability, the center contact is made of beryllium copper with gold plating over non-magnetic nickel-phosphorus underplating, while the body is stainless steel with a passivated finish. PTFE insulation provides excellent dielectric properties. Mechanical integrity includes a slide-on coupling mechanism, ≥1000 mating cycles, center contact captivation ≥27 N, engagement force ≤13.5 N, and disengagement force ≥2.0 N. Featuring crimp contact attachment, it supports .085 and RG-405 cable types, and is fully compatible with Semi-Rigid and Semi-Flexible coaxial cable assemblies.
ROSNOL’s precision-engineered solutions offer a competitive alternative to products from leading manufacturers in Europe, the USA, and other global markets. All ROSNOL components are manufactured in ISO 9001-certified facilities and fully comply with RoHS and REACH regulations, ensuring environmental safety and global regulatory alignment. Customization services for materials, plating, and mechanical design are available to support specialized requirements across a wide range of RF and microwave applications.
