SQT-149-01-L-5 rectangular connectors offer a broad selection of headers, receptacles, and female sockets for easy integration into any device. The double row design minimizes crosstalk and ensures clean and accurate signal transmission at high speeds. The connector housing is UL 94V-0 rated and the contacts are made from gold-plated copper for maximum corrosion resistance.

Product Applications

The low profile, small footprint, and multiple mounting options of SQT-149-01-L-5 connectors make them an ideal choice for many applications. Common applications include server-to-server interconnects, point-to-point connections, telecom/datacom, test instruments, and PoE devices. The connector can also be used in space-constrained areas, such as embedded systems and mezzanine boards.

Working Principle

SQT-149-01-L-5 rectangular connectors utilize a well-known friction retaining system to hold two mating halves together, making the connection reliable and vibration resistant. The friction retention system is made up of two parts: a helical retaining spring and a locking tongue/tab. The locking tongue/tab is part of one of the mating halves, while the helical spring is part of the other. As the halves are mated together, the helical spring is compressed, which increases the locking force of the mating halves. Additionally, the tongue/tab ensures that the halves are properly aligned before mating, further increasing the reliability of the connection.

Conclusion

SQT-149-01-L-5 rectangular connectors are designed for applications that require clean and accurate high speed signal connections. They offer a broad selection of headers, receptacles, and female sockets for easy integration into any device. These connectors use a friction retention system to provide a reliable, vibration resistant connection. Common applications include server-to-server interconnects, point-to-point connections, telecom/datacom, test instruments, and PoE devices.
