Background

A backplane connector is an electrical connector which is commonly used for the purpose of connecting the components of a computer bus. The connectors are usually configured to fit in a particular type of backplane panel, which is a standardized printed-circuit board used to provide a mounting hardware platform for the electrical connectors.

The 120681-2 backplane connector, manufactured by interconnect specialist Molex, belongs to the company\'s range of specialized connectors which are often used in unique applications.

Applications

The Molex 120681-2 backplane connector is designed for use in applications requiring a high number of connections in a small space. A variety of pin configurations are available, which allows for use in different applications.

The 120681-2 backplane connector is commonly used in medical instrumentation, robotics and internet communications systems. The connector offers excellent EMI shielding for use in any EMI sensitive application and the rugged die-cast shells offer reliable mechanical protection for reliable operation in any environment.

Working Principle

The 120681-2 connector is a shielded variant of the standard Molex 0.50mm contact used in many backplane connectors. The contacts within the connector are retained using a dual-beam searcher system which locks each contact into place when mated and allows for rapid disassembly of the connector and reinsertion of the contact bodies.

The connector features two contact positions at one end, and four contact positions at the other, allowing for low-risk and reliable signal and power routing with a minimum of connection steps. The rugged die-cast housings of the 120681-2 connector provide excellent protection for the contacts from shock, vibration and temperature extremes.

The 120681-2 connector uses standard Molex mating hardware, allowing for efficient configuration and assembly. The normal mating system is composed of the receptacle (plug) which is inserted into the backplane and the header (socket) which mates with the receptacle and is connected to the device. The header is available in a male or female configuration depending on the application.

Conclusion

The Molex 120681-2 backplane connector is an ideal solution for applications requiring a high number of connections in a small space. The connector provides excellent EMI shielding and robust mechanical protection, ensuring reliable and stable performance. The connector is easy to configure and assemble, allowing for efficient installation and removal.
