68685-208LF Application Field and Working Principle

68685-208LF is a rectangular connector that belongs to Headers, Receptacles, and Female sockets. It is a wide used connector in the application of electronic, industrial process control, automotive, PC, data and communication, and instrumentation. It is designed with a heat resistant thermoplastic base material and has two rows of surface mount contacts with a standard 0.4mm contact pitch hub in between.

Features

• - Suitable for high-density surface mount routing
• - 0.4 mm terminal pitch
• - Brown UL94V-0 thermoplastic
• - High temperature resistant
• - Large variety of compatible mating contacts
• - UL/CSA approved

Applications

The connector is widely used in many fields that require signal transmission and power supply, such as:

• - Industrial process control
• - Automotive
• - PC and Data
• - Communication and instrumentation

Working Principle

The working principle of the 68685-208LF connector is quite simple. In a single-row rectangular connector, the two rows of contacts (pins or sockets) are arranged in parallel between the two sides of the connector. The pins are inserted into the corresponding sockets or holes, usually held together by friction. When the two sides are plugged in, the pins create a physical and electrical connection. In a double-row rectangular connector, two sets of pins are arranged one above the other and the pins and sockets are press-fitted into the holes of the circuit substrates of the two housing parts to create a physical and electrical connection.

The 68685-208LF connector is one type of two-row rectangular connectors, and it is designed to be easy to mount on the surface mount type PCB. It has 0.4mm contact pitch hub in between two rows of terminals, allowing it to be used for high-density surface mount routing.

The material of 68685-208LF connector is heat resistant thermoplastic, UL 94V-0, guaranteeing good performance under high temperatures and harsh environment. It is UL/CSA approved, and can be used in a wide variety of applications.
