Application Field

The FX5-68S2A-DSA is a versatile mezzanine connector that can be applied to a number of industries. It can serve in the fields of consumer electronics, medical, communications, automotive, military, and aerospace industries. Due to its high speed, high power, and robust design, it’s also commonly used in harsh environment applications, such as high-temperature or high-vibration applications. Its low-profile design and secure locking features make it suitable for high-density applications where space is limited.

Working Principle

The FX5-68S2A-DSA connector consists of two board-to-board mating connectors that are joined together to form an interface. The two connectors are held in place by two sets of locking ribs located on the mating sides. When the connector is properly mated, the two sets of ribs will lock into place and restrict separation. This secure locking design provides good strain relief and resists vibration, thus maintaining contact reliability.

The pins of the mating connectors will engage a combination of surface mount and through hole components on the printed circuit board. Each contact is crimped and soldered to ensure mechanical and electrical performance. The contacts are configured to ensure signal integrity and minimize crosstalk. The overall contact resistance is also reduced to maintain low signal attenuation.

The board-to-board configuration of the FX5-68S2A-DSA allows for easy high-speed data transmission and power transfer. The connector utilizes a combination of 50 Ω single-ended and 100 Ω differential signals to support high-speed data transfer of up to 12.5 Gb/s. The connector is also designed to handle up to 8 amps of current, enabling it to be used in applications that require a high power connection.

Conclusion

The FX5-68S2A-DSA is a versatile board-to-board mezzanine connector ideal for high speed and high power applications. Its robust construction makes it suitable for harsh environment applications and its two sets of locking ribs provides stable and reliable connection for various applications. This connector is widely used in industries such as consumer electronics, medical, automotive, military, and aerospace, and is suitable for high-density applications where space is limited.
