Introduction

The SMS9R1 is a field-mountable rectangular connector housing with 4 contacts. It is designed to couple high-frequency signals for interconnection of modular components in equipment servicing markets including audio, video, telecom, industrial, medical, gaming and instrumentation. Adding to its flexibility, these connector housings are available as either screw-terminated or solder-terminated.

Design & Construction

The SMS9R1 is a two-piece design that features both a polarized and audible mating indicator for correct mating. The 4-position plug housing is based on a threaded locking mechanism that gives it a secure connection when mated with opposing thread terminals, and an isolated pin-type connection system that provides a swift connection on the four-position terminal. The two-piece design allows for easy assembly and disassembly, making fabrication and maintenance of the connector housings very convenient. The housing is also polarized to provide visual assurance for proper mating and ensure that the signal path is correctly aligned.

The housings are white, made from a UL94V0 rated thermoplastic for durability and weatherability. They also feature secure mounting cubicles capable of accepting a range of standard mechanical and physical fixing solutions plus multiple wiring options. Blind mating and PCB cut-outs are also available to further simplify workmanship, assembly and inspection.

Working Principle

The SMS9R1\'s two-piece design is composed of a plug housing and a terminal. To ensure maximum electrical performance, the terminals are gold-plated and feature a unique pin-type connection system with high contact forces. The plug housing integrates a dual-cavity security lock that mates with the four-position terminals for secure contact stability.

When mated, the asperity between the two elements ensure positive contact and prevent deformation of the contact body. The mating results in a high retention force due to the tension between the locking fingers and the sides of the terminal. This locks the terminal in place and ensures spatial accuracy that is critical for secure signal transfer.

The signal path is shown in its mating window for visual assurance of proper mating prior to application. Furthermore, a spring-loaded mating mechanism ensures that only lenses with the correct footprints can be mate with the plug housing. This provides a safe, foolproof way to ensure correct imagery transfer.

Conclusion

The SMS9R1 is a rectangular connector housing designed for high frequency signals in demanding applications such as audio, video, telecom, industrial, medical, gaming and instrumentation. It features a two-piece design with a plug housing and four-position terminal, as well as a secure threaded locking mechanism and an isolated pin-type connection system for easy assembly and disassembly. Its blind mating and PCB cut-outs further simplify workmanship, assembly and inspection. With its secure contact stability and visual assurance for proper mating, the SMS9R1 ensures a reliable signal transfer in demanding applications.
