The HMTSW-220-11-T-S-011-RA: Application Field and Working Principle

The HMTSW-220-11-T-S-011-RA is a surface mount connector belonging to the rectangular headers family in the male pin category of connectors. This is a low profile connector which is designed for through hole applications and occupies minimal real estate on the PCB. It is suitable for power applications with high electrical performance and strong mechanical stability.

Application Fields

The HMTSW-220-11-T-S-011-RA is widely used in many industries and applications like computers, laptops, consumer electronics, telecoms, mobile phones, etc. It is mainly used for power, signal, and data transmission, enabling a wide variety of connections in any number of PCBs. It boasts of high quality performance and reliable contact connection, making it a great choice for device manufacturers needing a reliable electrical connection.

Moreover, this type of connectors also provides a quick and efficient way to add or replace electrical equipment, allowing for greater flexibility and a faster time to market. Its small size allows for use in applications such as wearable technology, where space is a premium and minimal size components are needed.

Working Principle

The HMTSW-220-11-T-S-011-RA uses a surface-mount technology (SMT) design for its contacts. SMT contacts are generally made of copper alloy with a gold-plated finish. This ensures high current carrying capability and high mechanical stability while also protecting against corrosive materials. Connectors in this series have a 2.20 mm contact pitch and 11 contacts, and are designed for use with flat copper-clad boards.

The contact pads of the contacts are slightly funnel-shaped for easy loading and precise contact alignment. There are three contact retention points on each row of the 11 contacts. Each contact is press fit in the SMT position during the manufacturing process to provide secure fixing. Both the wire-to-board and board-to-board contacts come with a retention force rating of 2.30N to ensure reliable connectivity. The connector has a current capacity of 7.7A with a voltage rating of 10V and is UL-approved.

The housing has four independent metal walls for effective shielding effectiveness and additional durability. It is designed for use with wires that are 26 to 28 AWG and has through-hole support with post-termination insulation. Furthermore, the housing has integrated 10 MΩ of insulation resistance which prevents crosstalk and ensures that the electrical connections are secure.

The HMTSW-220-11-T-S-011-RA is a highly reliable connector and is designed to address requirements for a wide range of consumer and industrial electronic applications. It provides a secure and durable connection, increase flexibility in design, and maximized PCB profitability with a small size connector.
