In summary, the TE Connectivity MTA connector housings are offered in a variety of configurations to meet the specific retention and polarization needs of each application. MTA connectors with a plain configuration allow for mating with any type of header. Polarized connectors feature two tabs on the receptacle that ensure proper mating with the correct sized header. Locking ramps add an audible latch to confirm mating as well as provide increased mating retention. A receptacle with both locking ramps and polarizing tabs adds the audible latch, increases retention, and ensures correct mating with the proper sized header.
