Rectangular connectors, or rectangular head connectors, are a commonly used type of electrical connector. They are named for their shape, the rectangular housing, relative to other connectors, which are often cylindrical. Rectangular connectors come in various sizes and can be used for a variety of applications, ranging from the automotive industry to consumer electronics. This article provides an overview of the SSM-112-LM-DV-A-TR rectangular connector, outlining its application field and its basic working principle.

Applications

The SSM-112-LM-DV-A-TR is a multi purpose rectangular connector with keys and posts and is designed mainly for secondary applications. It is suitable for connector systems in instrumentation, measurement and control. It is suitable for mounting on printed circuit boards, but also for cable wiring, for instance when quick field wiring is necessary. It is also compatible with a wide range of mateable connectors with various voltage and current ratings, including 10A, 16A, 20A, and up to 35A with 600V (or up to 630V in newer model). Depending on the exact choice, additional features like watertightness and dust protection can be achieved.

Working Principle

The SSM-112-LM-DV-A-TR consists of two main parts, the housing and the contacts. The housing is made of thermoplastic material in shape of a rectangular sleeve. The contacts are generally two or three sturdy rivet-type pins which are capable of carrying the relevant current and voltage ratings of the connector. The contacts slide into the corresponding slots in the body of the connector, and the close the connection with a strong snap. The contacts are made from copper, silver or gold plating and are designed to ensure a reliable and accurate connection.

Conclusion

The SSM-112-LM-DV-A-TR is a universal and versatile rectangular connector suitable for a variety of applications, ranging from instrumentation and secondary wiring, to PC boards mounting and cable wiring. It features robust and reliable contacts in a thermoplastic body, able to carry currents and voltages up to 35A and 630V. Depending on the choice of additional accessories, the connection can be adapted for special requirements, such as dust protection and watertightness.
