• Electronic boards with high-speed data communication.

As the connector provides superior mechanical stability, it can be used in security critical applications such as modern automotive, aerospace, military or other mission-critical applications.

Contacts

1757682-1 connector is an 8 mm Duplex connector, with 2 coax lanes and 1 shielded differential lane for signals that requires more protection. This type of connection offers increased protection to the signal thanks to the shielding effect of the LSRN between the two board planes.

• Type 1: 1 x Differential
• Type 2: 2 x Coax (Outer Shielded)
• Type 3: 1 x Differential + 2 x Coax

The Duplex construction is designed to transmit high-speed and different analog/digital signals at differential, coaxial, and shielded differential modes. The special C-clip and probe system ensures accurate connection between the board planes that prolongs the reliability of the connection.

Working Principle

1757682-1 connection system is designed for high-density applications and is ideal for tight space and high speed data communication. The unique design of the connector ensures maximum mechanical stability to the connection points. The connector is designed to perform in temperature operating range of -65°C to +125°C.

The connection system is equipped with LSRN contact that provides increased EMI protection and high-speed data rate. The differential contacts are designed to provide stability to the transmission line that ensures signal integrity. The coaxial contact protects the inner signal from outside noise, as well as the outer signal from the inner signal. The shield provides reduced crosstalk and minimizes the risk of external interference.

The special C-clip contact ensures stable connection that is able to hold up in an environment with high vibration. The contacts are designed to provide secure connection even under tight space. The secure connection ensures efficient transfer of data and provides long-term reliability to the connection points.

Conclusion

1757682-1 connection system is a type of backplane connector that is designed for high-density applications. The connector offers superior mechanical stability for long-term performance of the equipment. Its 8 mm board-to-board connection makes it suitable for a wide range of electronic applications, from automotive and telecommunication equipment to industrial instrumentation and aerospace applications.
