Rectangular Connectors - Headers, Male Pins

The HTSW-202-09-G-S-RE is a rectangular connector, specifically a header with male pins, featuring very low-profile and wide-ranging applications. Manufactured by Hirose, this dimensional specification connector is made use of in headset applications, audio, telecom, automotive industry, and medical fields in order to assure quick and easy connection. The header uses a snap-in mounting style which is particularly conducive for blind-mate sockets and further ensures secure connections while also providing high-speed signals over long distances.

Design Specifications

The HTSW-202-09-G-S-RE header has a number of design specifications. Its contact arrangement is of TSSOP type, with 2 parallel rows and 20 positions in each row. The speed rating is 25 GBit/s. Furthermore, it is a right-angle type of connector, having a 1.25mm pitch, and made of stamped and formed contacts and an insulation body. Lastly, for easier mating, the header features a molded polarizing recess.

Materials Used

The HTSW-202-09-G-S-RE header is made with high-grade, durable material in order to ensure long-term stability and reliable electrical and mechanical performance. The contact plating is done with gold, the connector is made with UL 94V-0 rated polycarbonate, and the crimp is a tin plated copper alloy.

Compatibility

The Hirose HTSW-202-09-G-S-RE header is designed and built to mate with a number of similar connectors, namely Hirose’s EX2.0DF-20P-S-P-06 which is an SMT-type of connector, and the HFE-201-09-G-01 which is a surface Mount-type of connector. Moreover, it is also compatible with most industry standard circuit board sizes.

Features and Benefits

The low-profile design of the Hirose HTSW-202-09-G-S-RE header provides a number of advantages despite its small size. Besides the standard advantages of a Hirose connector such as its durable design with high contact counts, it offers improved connection reliability, as well as superior board-level EMI performance due to its highly shielded design.

In addition, because of the overall design economy, lightweight and space saving benefits, it is particularly suitable for use in very limited and low-profile application spaces. Another benefit of the HTSW-202-09-G-S-RE is its wide temperature range. This gives it the ability to work optimally and maintain reliable electrical connections from -15 and +105 ˚C in both air-bounded as well as condensation-laden environments.

Working Principle

The working principle of the HTSW-202-09-G-S-RE header relies essentially on its two distinct parts, the housing and contacts. The housing provides secure, complete mating, while the contacts have the main electrical function of conducting and transferring the current in and out of the system.

The contacts feature insulation displacement technology, which eliminates the need of manual soldering thus making it reliable and durable. On the other hand, the header also allows complete polarization, allowing for easy mating, and even enabling blind mating with its a snap-latch. And because of its flexible eight-finger design, it is even further beneficial for efficient signal transmission.

Conclusion

The Hirose HTSW-202-09-G-S-RE is a very useful header with male pins that can be used in a variety of applications, especially in headset, audio, telecom, automotive and medical fields. Even though it is low-profile, it offers numerous features and benefits, such as improved connection reliability, board-level EMI performance, and the ability to mate with similar connectors and industry standard circuit boards. And thanks to its insulation displacement technology and flexible 8-finger design, it provides highly efficient signal transmission with safe, secure connections.
