FTSH-121-02-SM-MT Application Field and Working Principle

Rectangular Connectors - Headers, Male Pins

The FTSH-121-02-SM-MT is a surface mounting rectangular connector with male pins from the FTSH series. As a space-saving alternative for through-hole headers, this connector is designed to provide a secure and reliable connection in a variety of applications.The FTSH-121-02-SM-MT is a two-row, right angle mounting connector with a maximum current rating of 7.5A and maximum voltage rating of 250VAC. It is available in multiple polarization and connector numbers, with each polarization having varying male pin lengths and columns. This connector can be pre-loaded for easier mating and use with standard rectilinear interface and housings, which makes it suitable for applications that require a fast assembly process.The versatile design of this connector also features a combination of low-contact resistance, excellent signal transmission, and high temperature resistance. It has two pins per row and low profile which allows for flush mount installation. The pins are fully insulated to ensure safety when connecting to appliances with metal housings. The connector also includes an extra, self-latching feature for extra retention and mechanical strength, as well as screw locking functionality for increased electrical contact performance.The FTSH-121-02-SM-MT is primarily used in industrial automation, consumer electronics, gaming, automotive, medical, and other applications that require a fast assembly process and reliable connection. It is also commonly used as a replacement for a through-hole header, as the low-profile design ensures that the connection is secure and quick to access in tight spaces.In order to understand the working principle of this connector, it is important to understand its composition and design. The connector features a two-piece assembly consisting of a pin segment and a metal contact body, with the pin segment being crimped onto the body. This two-piece assembly ensures a secure connection between the pin and body while also providing a low-profile design for a flush mount installation. The metal contact body is spring-loaded and provides electrical contact between the connector pin and the mating surface. When the connector is mated, the contact body is pushed into its socket in the mating surface which creates an electrical connection. The spring-loaded design ensures that the contact body is securely retained in the mating surface, even after vibrations cause by the operation of the device.The FTSH-121-02-SM-MT is a versatile and reliable connector for a variety of applications. Its combination of low-contact resistance, excellent signal transmission, and high temperature resistance make it an ideal connector for fast assembly in tight spaces. Furthermore, its two-piece assembly and spring-loaded design provide secure and reliable connections with minimal assembly time.
