New spring fingers outer contact
All BMA female connectors adopt a redesigned spring finger outer contact for improved performance.
The redesign of our BMA female connector was launched in 2007. The main design improvement is a "3 in 1" concept with a "one piece" stamped contact which replaces 3 different piece parts on previous BMA design.
The spring fingers design was chosen thanks to a thorough simulation which showed it achieves the best compromise between high electrical performance and good mechanical characteristics. Simulation helped adjusting width, length, number of slots and circular shape of the contact for best results.
The redesign team also improved the protective sleeve assembled on female center contacts which securely guides the male pin during mating operation. Both BMA standard and BMA commercial product ranges benefit from these innovations.
Features & Benefits
Innovative stamped sleeve, the cutting edge of stamping technology
- Equal or better RF performances than existing contacts
- Outstanding life cycle, repeatable insertion/extraction forces guaranteed
- Designed to avoid bent petals situation in all mating situation
- Smaller outside diameter
- Fewer parts offer less constraint on supply chain
- Full intermateability between existing and new BMA
New part numbers have been introduced for BMA female connectors with the new spring finger outer contact. Old P/N's will be supported for a limited period of time with last buy order option.
Applications
The main application for BMA connectors is blind mate interconnect for back panels and microwave modules in radar, electronic warfare and telecom equipment. BMA "floating" connectors are typicaly used in these applications.
The smaller outside diameter of the new BMA female contact is also a great advantage when using size 8 BMA contacts inserted in multipin rectangular or circular MIL-38999 connectors.
Radiall also manufactures low loss cable assemblies and harnesses using in-house SHF cable and the new BMA connectors.
