Introduction

The HMTSW-112-11-S-T-730 is categorized under rectangular connectors with headers and male pins. This connector type provides an electrical connection between two surfaces. This type of connector has been traditionally used in the telecommunications and computing industry. The most popular use of this connector is in electronics where it is employed in a wide variety of devices including communications systems, televisions, optical systems, musical instruments, stereocasting equipment, and automotive electronics. The purpose of this article is to provide an overview of the application fields and working principle of the HMTSW-112-11-S-T-730 connector.

Description and Characteristics

The HMTSW-112-11-S-T-730 connector is a two-piece molded plastic arrangement that is made up of a header block and male pins. The rectangular header block has three rows containing 11 terminal pins each, thereby providing a total of 33 terminal pins for connection. This block has four mounting bosses at each of the four corners. Each pair of the mounting bosses has corresponding holes for screws or other types of fastening devices. For ease of mating and unmating, the connector has an oval end tab that fits into the mating keyway for the mating plug connector. The use of this tab reduces the risk of misalignment and damage to the connector and its components.

Specifications

The HMTSW-112-11-S-T-730 connector is rated for use in environments with a maximum operating temperature of +105°C and a minimum temperature of -40°C. The voltage withstand capacity is rated at 500V. The current rating is 2.5A for power and 1A for signal. The insulation resistance for this connector is greater than 500 mΩ when tested using 500V testing voltage. The contact resistance is also low, running at 2.5mΩ or less. Finally, the pin contact force is rated at 30 - 55N, depending on the pin size.

Application Fields and Working Principle

The HMTSW-112-11-S-T-730 is mainly used in the telecommunications and computing industry. The selector applications of this connector can be categorized as follows: personal computers, workstations, data communication systems, office equipment, retail counters, banking systems, ATM machines, gaming systems, systems engineering, video surveillance systems, high-speed data communication, multimedia systems, entertainment systems, and more. The working principle of the HMTSW-112-11-S-T-730 connector is based on the electrical contact of its male and female pins. The electrical contact is ensured by tight fitting of the male pins into corresponding sockets in the header block. The contact force is established by the expansion pins of the male pins which is maintained by the contact spring that is present in the header block. Current then flows from the male pin through the contact spring and eventually to the corresponding female pin.

Conclusion

The HMTSW-112-11-S-T-730 connector is commonly used in the telecommunications and computing industry due to its ability to provide secure electrical connections between two surfaces. It offers a great level of performance with a voltage withstand of 500V, a current rating of 2.5A for power and 1A for signal and insulation resistance of more than 500mΩ when tested using 500V testing voltage. The working principle of this connector is based on the electrical contact established through the male and female pins of the connector. In conclusion, the HMTSW-112-11-S-T-730 connector is a reliable and secure connection solution.
