They are typically used in a multi-pin arrangement between racks and panels, daughtercard to backplane, or similar applications where the connector is not mated by itself, but rather by the action of inserting the entire unit or module.
Blind mate RF connectors are generally intended to be used without wrenches or other tools, but can come packaged in a multiport configuration that includes mounting hardware or provided as inserts in a circular connector such as a MIL-DTL-38999.
Some examples of blind mate RF interfaces include BMA (OSP), BMMA (OSSP), SMP, SMPM, SMPS, and Planar Crown connectors.
These styles are typically used when the mate is a cable connector and might see a significant force that would normally demate the connection.
Other configurations feature a smooth bore into which the mate simply slides to connect.
