L77DFBF25SMP10

Introduction

The D-Sub Connectors is a type of electrical connector used to interconnect electronic devices in lieu of soldering. Although the connectors are primarily used to provide a mechanical connection, some contacts may also contain electrical connections to create a circuit. The most common D-Sub Connectors is from the family of connectors known as the L77DFBF25SMP10. It is a three-row, 25-pin male-to-female cable.

Application Field

The primary use of the L77DFBF25SMP10 is for data and communication applications. It is often used to transmit video signals over long cable runs to connect computers and other peripheral devices. It is also used in the automotive industry for relay and control wiring. This connector type is also often seen in industrial automation and robotics, as well as in medical devices and telecommunications systems.

Working Principle

The L77DFBF25SMP10 is a high-density connector with three organized rows of pins. The pins are situated at regular intervals, with the male connector featuring 25, 9mm long pins in three rows of 8, 8 and 9 pins respectively. The pins are then inserted into the corresponding female connector and secured in place with a thumbscrew or a cable clamp. The outer shell or housing holds the pins and seals the connection, keeping out dust and protecting against accidental contact.

The wires used in the connector are arranged in two rows, with each row containing twelve wires and each wire having an outside diameter of 0.5mm. The connector also has an insulation displacement contact (IDC) design, which allows the wire to be inserted into the connector without the need for soldering. Instead, a punch down tool is used to insert the wires into the recesses in the connector.

Conclusion

The L77DFBF25SMP10 connector is a versatile and reliable connection method for data and communication applications, as well as automotive control, industrial control and automation, medical devices, and telecommunications systems. Its high-density design allows for more connections than other connector types, while the insulation displacement contact (IDC) design eliminates the need for soldering and makes the connection process easier and faster.
