Rectangular connectors refer to one of the most widespread types of electronic connectors. Typically, they consist of two mating parts, one with pins, the other with hidden sockets. The most common sizes of rectangular connectors are 26, 50, 51 and 70. Among these connectors, SSQ-120-02-G-S-RA is a three-rows, right angle (RA) type header with 2.00 mm (0.079”) pitch. Specifically, it belongs to the Header family.

Application Field

SSQ-120-02-G-S-RA is ideally suited for applications that require space-saving, high-density connections. It works best in applications where a combination of signal and power connections are required, such as personal computers, instrumentation and communication equipment, and even automotive infotainment applications. This header connector is compliant with RoHS, UL, and CSA standards, meaning it can safely and reliably be used in a variety of applications.

Working Principle

The principle of SSQ-120-02-G-S-RA rectangular header is the same as that of any other conventional header connectors. Generally, the headers consist of two mating parts: the socket with hidden pins and the pin with male blades. They connect the two mating parts by sliding them together and the male pins connect to the hidden sockets. The connectors are typically secured with latches at the sides to prevent them from coming apart.

The SSQ-120-02-G-S-RA header has two mating options to choose from: straight (S) and right angle (RA). When picking out the right angle (RA) option, the pins and sockets will be facing to the sides, while they will be facing forward and downward when choosing the straight (S) option. For both variations, the headers come pre-crimped and are designed with surface mount retention legs to ensure secure connections.

The SSQ-120-02-G-S-RA headers are designed to provide high-density packing and long-term reliability. It is meant for low-current applications and each terminal is designed to operate with an amperage rating of up to 0.5 Amp. The contacts are designed in a reversed configuration, meaning the female contact is on the header and the male contact is on the receptacle.

This header also uses gold plating to ensure a reliable connection and a lower contact resistance. Furthermore, the header also features smooth surfaces that provide improved mating and insertion force, as well as more secure contact force for making a long-term connection.

Conclusion

SSQ-120-02-G-S-RA is a type of rectangular headers with two mating options available and is perfect for applications requiring high-density connections. It has a 2.00mm (0.079”) pitch and is compliant with RoHS, UL, and CSA standards. This header comes pre-crimped and uses gold plating to ensure a reliable connection and lower contact resistance. It is designed to operate with an amperage rating of up to 0.5 Amp. Ultimately, SSQ-120-02-G-S-RA is a great choice of connectors for applications requiring space-saving, high-density connections.
