DF14-25P-1.25H (20) connectors, also known as Male Pins, are a type of rectangular connectors. They are most commonly used in consumer electronics to provide a secure connection between a printed circuit board and another circuit, such as a computer or smartphone. Manufactured to provide a reliable mating connection in high density applications, Male Pins have been used in numerous applications, including consumer electronics, industrial control, automotive, medical, and military aerospace.

Their main features consist of a standardised 0.1 inch pitch, an overall outer height of 1.25 mm, a current capacity of up to 5.0A per pin, and a contact resistance of <50 mohm per contact (max). Furthermore, Male Pins are capable of withstanding 500 cycles of mating and un-mating cycles and have an operating life of 500 mating and un-mating cycles. Finally, they are compatible with both wave or reflow soldering methods.

Due to their ability to securely and reliably mate printed circuit boards, Male Pins have a wide range of applications. For instance, they can be used for automotive electronic control units, soft-switches, touch sensors, automotive interior lighting, integrated circuit arrays, automotive diagnostic systems, and more. Furthermore, these connectors are suitable for use in any electronic appliance requiring a strong, reliable connection between different circuits.

In terms of working principle, Male Pins typically feature multiple connection points (20 in the DF14-25P-1.25H model). These connection points allow for an up to 5.0A current to pass from one board to the other, when the pins are mated. Typically, the female contact of a Female Header receives the male pin, thus creating the connection.

To ensure proper engagement between the Female Header and the Male Pin, the pins must be inserted into the female contact. To do this, the user typically employs force to insert the pins until the female contact properly mates with the pins. After proper engagement is achieved, an electronic signal is transmitted through the contacts, thus allowing for the proper functioning of the system. Additionally, for added security when the circuits are in use, most Female Headers include a latch mechanism which, when engaged, prevents unintended disconnection.

Overall, DF14-25P-1.25H (20) Male Pins, and connectors in general, allow for secure and reliable connections between two circuits. Their standardised pitch and housing along with their contact resistance, mating cycles and current carrying capacity make them suitable for a variety of applications, ranging from consumer electronics to automotive and medical. They can also be easily employed thanks to their simple design, and can prevent unintentional disconnection with the use of a latch mechanism.
