DBA-25P-K87-F0

D-Sub, D-shaped connectors are one of the oldest yet still most frequently found connector types used in the electronics industry. The standard D-sub miniaturized design is the DBA-25P-K87-F0. Its popularity is due to the fact that it provides various sizes (ranging from 2 to 49 contacts), multiple forms of mating (front panel, cable to cable, cable to computer boards, daughterboards, etc.), and custom options such as water sealing, EMI shielding, PCB assembly, and termination.

Application Field

The DBA-25P-K87-F0 is applicable in many applications where tight space is an issue. It is often used in network cabling applications, consumer electronics, to provide reliable data transmission interface. The smallest number of contacts recommended is two, while the biggest is twenty-five. The standard number generally available is two, four, nine, fifteen, and twenty-five. The application fields for this type of connector include data processing, office automation, precision instruments, audio systems, and peripheral equipment. Other applications include medical equipment, automotive equipment, telecommunications, and military applications.

Pin Layout

The pins of the DBA-25P-K87-F0 are arranged in a dual-row style. This means that each row of pins is made up of two pins, with the total number of pins being twice that of the total number of contacts. The pins are arranged in parallel strips with five contacts on each strip, forming a stacked configuration. This configuration helps provide small sizes, while allowing for flexibility with different sizes, shapes, and contact configurations.

Mating Type

The DBA-25P-K87-F0 uses a standard D-type mating system. This system consists of two main components: the male pin, and the female connector. The male pin is inserted into the female connector, and the two are held together through a latch. The latch allows for easy attachment and detachment of the mating components. The male pin is typically designed with a flat bottom surface, while the female connector features a slotted body. Because the two components of the D-type connector can easily be removed, this type of mating system is often used in times when components need to be changed, upgraded, or repaired.

Working Principle

The DBA-25P-K87-F0 connector\'s working principle is based on the application of an electrical current. The electrical current flows from one contact, passes through the conductive pins, and ends up on the other contact. As the current passes through the pins and contacts, the electrical current is used to establish a data connection. This data connection can be used to transmit digital signals, control signals, or power signals. With the DBA-25P-K87-F0, up to 2.5A at 50V can be applied.

Conclusion

The DBA-25P-K87-F0 is one of the oldest yet still most reliable and frequently used connectors in the electronics industry. Its D-type mating type allows for easy attachment and detachment of the mating components, while its dual-row pin layout provides small size and flexibility. With the DBA-25P-K87-F0, up to 2.5A at 50V can be applied for data connection, digital and control signals, and power signals. This makes the DBA-25P-K87-F0 the perfect choice for your networking, consumer electronics, medical, automotive, telecommunication, and military applications.
