The EJH-120-01-S-D-SM-LC-39 is a type of rectangular connector header, with male pins attached. It has two variants, a standard variant, with 2.54 mm pitch and 100 pin count, and a high-density variant with 1.27 mm pitch, also known as 2mm pitch, and 120 pin count. This header is metal shielded, single coated and made with press-fit technology. In terms of its physical design, the EJH-120-01-S-D-SM-LC-39 has a length of 50 mm, and a width of 15.55 mm, and the pins are each 3 mm in length.

This header has a number of applications, such as being used for connecting electronic components with boards, or for connecting two boards together. It is particularly useful when needing to connect high-speed pins for data transmission. The connector’s gold-plated contacts provide reliable electrical connection in the most demanding of applications and the metal shielding ensures optimal electromagnetic interference protection. Additionally, the press-fit technology reduces assembly time and increases consistency as the need for manual soldering is eliminated.

On a basic level, the working principle of this header is that it makes contact between the male pins and the female connectors of the board. Firstly, each pin of the male header is aligned with the contact holes of the board, and then the header is pressed down into place. This causes the connection between the board’s contacts and the male pins to be established. When the header is at the correct depth, the board can then be inserted into the electronic device and the connection is secured.

In conclusion, the EJH-120-01-S-D-SM-LC-39 is a type of rectangular header with male pins attached. Its two variants offer flexibility for different applications and the press-fit technology provides a reliable connection in a wide range of applications. The gold-plated contacts and metal shielding ensures electrical protection from interference, and the working principle is relatively simple – the male pins being connected to the board contacts when the header is pressed in.
