Rectangular connectors have long been the most popular connection option for electronic circuit board components. They used to be mainly used for signal and power transmission, but their use has grown in recent years to a number of applications that include audio, video, data and control lines. The 69155-314LF is a type of right angle header which has a number of features and great versatility.

Design

The 69155-314LF has a unique design which allows it to fit comfortably into the small footprints of many electronic devices. It is made of a gold plated brass material which enables excellent signal integrity and mechanical stability. It features a 2.8mm pitch, making it suitable for high speed applications.

The connector pins are arranged in a 2x40 array along the length of the 69155-314LF, with a pitch of 0.5mm between each pin. This allows for a maximum of 80 connections. The gold plated pins are also corrosion resistant, ensuring excellent service life.

Performance

The performance of the 69155-314LF is excellent, with low noise and signal loss. It is rated for a current of 1.5A per pin, and a voltage of up to 50V D.C. It is also highly resistant to shock and vibration, making it suitable for even the most demanding of applications.

The 69155-314LF also features a closed case design, ensuring optimal protection against dust, mechanical damage and contact with other metal parts.

Applications

The 69155-314LF is most commonly used for automotive applications, including remote keyless entry, powertrain control units, and other electronic control systems. It can also be found in medical devices, telecommunication equipment, and consumer electronics.

The 69155-314LF is also very popular in the industrial sector, with applications such as robots, machine tools, automation and control systems, and automation machines.

Working Principle

The 69155-314LF’s working principle is relatively simple, relying on electrical contacts to transmit signals, data and power. It works by having a set of pins which make contact with either wire or PCB pads, and then transmits the electrical signals as required.

The 69155-314LF relies on four major components. A conductor which carries electrical current, a dielectric which is used as an insulator, a physical separation between the contacts, and the contact itself.

The conductor is the main part responsible for transmitting the electrical current. It is typically made from brass and copper and is either plated with a thin layer of gold to provide protected contacts or it can be coated in a chemically resistant material such as PTFE.

The dielectric material helps to separate the contacts from one another and helps to reduce signal loss and other electrical interference. It is typically made from a variety of materials including insulating rubber, high temperature polymers, and glass-filled plastics.

The physical separation between contacts is provided by the connector’s housing. Depending on the type of connector, this can either be a snap-in type for quick disconnects, or a threaded type for more secure connections.

Lastly, the contact is the actual point of connection between the conductor and the PCB pad. It is often made from gold or silver plated brass and usually features a small spring to ensure a solid connection.

In conclusion, the 69155-314LF is a versatile right angle header which offers excellent signal integrity and stability. It is suitable for a wide range of applications and is designed for high speed transmission. It is also highly reliable and resistant to shock and vibration, making it suitable for harsh environments.
