Rectangular Connectors – Headers, Male Pins

HMTSW-102-22-T-S-440 is a header type of male pins in rectangular connectors. It is specifically designed for printed circuit boards (PCBs) that feature SMT (Surface Mounted Technology). The device is composed of two rows of 22 male pin contacts having 1.0 mm pitch (space between pins). The component is ready to use for applications that require a top entry style of soldering to be used.

General Characteristics

HMTSW-102-22-T-S-440 generally has an overall width of 22.93 mm and an overall length of 6.5 mm. This male pin header is composed of a mated pair of (1) Plug and (2) Receptacle consisting of two rows each with 22 pins. It has an operating temperature range from -55°C to 105°C, a relative humidity from 0 to 95%, and voltage rating of 50V. The contact crimping / contact holder material of the pin header is phosphor bronze.

Application Field and Working Principle

The primary application of HMTSW-102-22-T-S-440 is in circuit boards as part of male/female connectors. The device functions to connect two separate circuits by providing a male (Plug) and female (Receptacle) pin connector contact points. Male pins are oriented in a vertical arrangement and protrude outwards so that a plug-like arrangement can be made with an appropriate socket. When using a pin header, the female plug contacts should be inserted into the female socket contacts first. The female plug contacts should then make direct contact with the female socket contacts, and thus establish a connection between the two circuits. Additionally, the male pin header should be locked afterward in order to ensure a firm mating of the contacts.The HMTSW-102-22-T-S-440 is usually assembled on the PCB by soldering using a ‘top-down’ technique. First, the male plug contacts are inserted into solder paste panel. This concentrates the heat generated in the cross section of the contacts to help rapid heat dissipation. Then, the joint should be soldered by reflow process. Finally, the joint can be examined through X-ray inspection process to check for solder defects.

Conclusion

The HMTSW-102-22-T-S-440 is a small but important device that enables connection of two separate circuits. With its 22 male pins, it is an important tool for modern printed circuit boards that require Surface Mount Technology. It is generally locked after insertion to ensure a secure mating of the contacts and is typically soldered using a ‘top-down’ process. All of these characteristics make the HMTSW-102-22-T-S-440 a suitable and reliable solution for various circuit board needs.
