Answer :

Answer:

The number expressed after the two letters in the name of a D-sub miniature connector indicates the number of pins or contacts that the connector has.

For example, in a D-sub connector labeled as DB-25:

- "D" refers to the D-sub connector family.

- "B" refers to the shell size and arrangement.

- "25" indicates that the connector has 25 pins or contacts.

Therefore, the number after the two letters ("DB" in this case) indicates the characteristic of the D-sub connector related to the number of pins or contacts it has.

Explanation:

D-sub connectors come in various configurations, categorized by the number of pins or sockets they have. The most common types are DB-9, DB-15, DB-25, and HD-15 connectors. The number following "DB" or "HD" indicates the total number of pins, including both signal and ground pins.
