Rectangular connectors have been widely used in many electronic applications to securely interconnect two circuits. The LTMM-120-02-G-D, a rectangular connector manufactured by Avnet, features reliable contact connection and vibration-resistant mechanical design which makes it perfect for use in medium density mechanical applications. This article will discuss the application field and working principle of this type of connector.

Application Field of the LTMM-120-02-G-D

The LTMM-120-02-G-D is a medium-density mechanical application connector made of a 0.250” centerline, two-piece header with 2.0mm center pins, and 2mm pin retention. This type of rectangular connector is an excellent solution for high frequency noise and vibration suppression applications. Due to its small and compact size, it is commonly used in wiring harnesses, backplanes, PCB Assemblies, and power supplies. The LTMM-120-02-G-D is suitable for a wide variety of applications including medical, consumer electronics, automotive, and telecom markets.

The LTMM-120-02-G-D’s gold-plated terminals, provide maximum corrosion resistance and low contact resistance. Its terminal lances ensure maximum electrical performance while the nylon insulators provide superior insulation barriers. This prevents electrical energy from flowing from one circuit to the other and maintain reliable data transmission. The terminals also exhibit high impact strength and longevity, which allows them to withstand multiple pluggings and unpluggings.

Working Principle of the LTMM-120-02-G-D

The LTMM-120-02-G-D connector is designed to securely connect two circuits with electrical current. The connector’s two-piece header consists of two rows of two-metre center pins called terminals. When two pieces of the connector are mated, the terminals create an electrical connection allowing current to pass between the two circuits.

To ensure maximum contact connection, the LTMM-120-02-G-D employs a two-piece header with dual-bevel lances. The dual-bevel lances serve as contact blades that fit into the mating channels of the other connector. This ensures a secure and reliable connection when two connector pieces are mated as the dual-bevel lances are able to penetrate through the mating channel and make contact with the other lances.

This type of rectangular connector also features a vibration-resistant mechanical design that allows it to with stand shocks and vibrations that commonly occur within medium-density mechanical applications. This is done through the use of a two-piece shell and pin retention. The two-piece shell provides both mechanical and electrical protection while the pin retention ensures that the pins stay securely connected and provide reliable electrical connection when the connector is mated.

Conclusion

The LTMM-120-02-G-D is a medium-density mechanical application connector capable of securely connecting two circuits. This type of rectangular connector is suitable for a wide variety of applications thanks to its gold-plated terminals which provide maximum corrosion resistance and low contact resistance, its two-piece shell and pin retention which provide mechanical and electrical protection, and its dual-bevel lances which ensure a secure and reliable connection when two pieces are mated. The LTMM-120-02-G-D is an excellent solution for high frequency noise and vibration suppression applications.
