Rectangular connectors are a type molded connector with terminals embedded into a plastic body. A primary feature is that they come fitted with electrical contacts or pins, providing the connection to soldered wires. This style of connector is quite popular for meeting the requirements of various applications within the electrical field.

The HMTSW-221-12-S-T-730-RA is a variant of the rectangular connector, functioning as a header with male pins. It is made up of 12 pins with a flat housing structure. This particular design features a total height of 0.827" and a minimal pin length of 0.295".

The application fields typically associated with these kinds of connectors are those involving power delivery, signal transmissions, and/or ground configurations. As such, they are best suited for connecting control circuits and coaxial systems, the total length of the conductors thus having a direct bearing on the transmission speed. These connectors are widely used in the industrial automation, telecommunications, aerospace, consumer electronics, and automotive sectors.

As for its working principle, the HMTSW-221-12-S-T-730-RA pins make contact with the mating receptacle when the connector is fit into the assembly, thereby effecting the electrical connection. This secure connection is further enhanced due to the polarization feature that ensures only the correct housing matches the contacts.

The HMTSW-221-12-S-T-730-RA is designed to meet the requirements of a high-reliability connection in even the harshest of thermal, mechanical and electrical stress environments. This is achieved by sporting features like the high retention force to prevent accidental misalignment between contacts, radical temperature cycling from -55°C to 105°C, and contact resistance values of 0.1 ohm at 4 amperes. Additionally, dual beam contacts optimise contact durability and strength, ensuring optimal electrical performance.

The materials used in this connector also make an impact on the efficacy of the working principle. The contact material is made up of pure copper and alloy plating with tin or gold, while the housing material comes in thermoplastic and thermoplastic elastomer options. These two elements combined enable the connector to achieve a very high current rating, with some variants being able to carry as much as 20 amperes.

All in all, the HMTSW-221-12-S-T-730-RA is a rectangular connector header with male pins that has a vast range of applications. It is designed to provide reliable electrical connection through its working principle, which utilises precision contact design, high retention force and a range of materials to ensure optimum performance.
