D-Sub Connectors are an ever-present and invaluable physical connection technology widely used in the electronic assemblies and computer industry. The common D-Sub Connector type, DBM21W1S1A7NA190, is a connector designed at 2.2 mm pitch and falls in the category of an ultra-miniature D-Sub.

Application Field

The DBMs offer an excellent solution for applications that require reliable and stable and compact interconnection. The 2.2 mm pitch denser contacts make the DBM21W1S1A7NA190 connector an ideal choice for highly demanding industrial, medical, and communication applications. It is a reliable connector product for indoor and outdoor communications, data center applications, and mid- to high-speed data transfer.

Working Principle

It is a two-part connector. The contact materials of the DBM21W1S1A7NA190 are stamped and formed, and the contact is inserted and snapped into the shell. It is designed and manufactured with aligning holes and insert pins, which allows easy offset mating in tight and confined spaces. The mating of connectors is done when the contacts on two mating connectors are inserted, with the help of aligning pins, in a positive locking type of connection, due to which the two mating connectors are held together with an ever-increasing force.

The mate-able contacts consist of machined pins or sockets, and each contact is released in a way that prevents the ingress of dust particles into the contact itself. The gold-plated contacts are capable of carrying up to 1A per contact and a total of 11A for the entire connector. It is also capable of transferring data at rates up to 1.25Gb/s.
