Rectangular Connectors - Headers, Male Pins

HMTSW-120-21-L-Q-430 is a rectangular connector header with male pins. It is composed of a long, thin plastic body containing multiple pins or sockets, and is widely used in electronics products. There are many areas of application for rectangular connectors, including computers, automation systems, consumer electronics, and medical technology.

Application Field

Rectangular connectors have become a widespread part of many electronics products such as computers, office equipment, consumer electronics, and audio equipment. They are used as connectors between computer boards, power supply modules, and switch panels. They are also used to connect various peripheral devices such as external hard drives, TVs, video recorders, speakers, and microphones.

Due to their small form factor and flexible design, they are also widely used in applications where space is at a premium, such as modems, keyboards, and laptops. They are also an essential component in the signal communication and control of computers, automation systems, and medical equipment with embedded controllers.

Working Principle

Rectangular connectors typically consist of a molded plastic body which holds multiple pins or sockets. The pins or sockets are spring-loaded and can either be soldered onto the circuit board, inserted into a socket, or may be held in place by a snap-lock system. The 2 sides of the connector are connected via one or more wires or cables.

The electrical connection between the two ends is established when the connector is mated, causing the contacts to move into contact and make a solid connection. Once the connection is made, the current can be directed to its destination, and data can be transmitted. The connection is broken when the connector is disconnected.

Rectangular connectors are usually rated according to their current handling capacity, voltage rating, and frequency. The current ratings for a rectangular header usually range from 1 up to 20 amps, depending on the specific model.
