TFML-125-02-S-D-A Rectangular Connectors - Headers, Male Pins Application Field and Working Principle

TFML-125-02-S-D-A rectangular connectors are a kind of very common rectangular connectors, known as headers, male pins. It is widely used in many applications, such as, but no limited to, digital products, communication products, instrumentation, industrial control, LED display, etc..In the application field, there are various types of rectangular connectors depending on the types of pins and housing. The TFML-125-02-S-D-A header is a right angle type with 2 rows and 4 polar counts and with maximum current rating of 15A. It is available with both pcb mount or chassis mount.The working principle of the rectangular connectors is designed to provide an electric connection between two plugs, and it is used to prevent a circuit from other foreign objects. Therefore, it is necessary to ensure a perfect connection between the two plugs.The TFML-125-02-S-D-A connectors have an outer housing that is connected with the male pin by screws. The contact force between the plug and pin is uniform and, the plating layers of the metal and gold are also evenly distributed, ensuring the contact surface under each point is even and not easily damaged. Additionally, the contact pin is also guaranteed with high quality and thickness, to ensure the connection is secure without loss of contact. The inner core area of the male pin is filled with a conductive agent. It mainly contains metal powder, thus providing a low resistance for the electrical connection. As for the contact tips, the Standard TFML-125-02-S-D-A connectors consist of two pieces of silver nickel and silver plated copper contacts which are gold plated. The silver nickel is the sliding portion which provides a soft and securely fastened contact while the gold plating ensures a low resistance in the connection.When the connector is plugged, the fingerprint force of the male pin will increase, which helps to create a very tight connection with the female socket, assuring a high level of contact consistency.Other than the TFML-125-02-S-D-A type, there are also other types of standards available to meet different needs of customers. The rectangular connectors used in military and aerospace applications must have higher strength than ordinary products. The MIL-C-22992 series connectors perform better in this aspect and are widely used in special fields.In general, the main application of the TFML-125-02-S-D-A rectangular connectors is in digital products, communication products, instrumentation, industrial control, LED display, etc. Their working principle emphasizes the contact force between the plug and pin, which is uniform and with gold alloy and nickel plating layers, ensuring a low resistance in the connection. So as to offer a reliable and secure connection when using the rectangular connectors.
