MTMM-122-12-G-D-275 Rectangular Connectors - Headers, Male Pins

Application Field

The MTMM-122-12-G-D-275 rectangular connector is a compact two-part connector designed for application in harsh environment such as automotive and industrial. 
It is a 2-position connector typically used for making electrical connections between two cables or between a cable and a printed circuit board (PCB).
The piece of the MTMM-122-12-G-D-275 is a header, which provides 12 pins for connection. The body of the header is made of phosphor bronze, while the gold-plated contact pins are made of brass. The contact pins are designed for a rear plug connection to a printed circuit board.
The contacts are type G, which is designed for robust application requiring a high level of vibration resistance and temperature stability. The header has IP67 ingress protection rating, meaning that it is highly resistant to dust and liquids.

Working Principle

In order to make connections between the MTMM-122-12-G-D-275 header and the other cable/PCB, the header is first inserted into a matching socket. The socket is designed to hold the header module against the PCB.
Once the header is in place, the contact pins are connected to the other cable or PCB.
The connection is made via a friction fit between the contact pins and the mating female contacts. The contacts are made of a high-conductivity material, which results in very low electrical resistance. This ensures that the electrical connection is reliable and won\'t cause electrical interference or “hot spots.” 
The connection is further strengthened by a firmly crimped connection between the mating parts.

In addition to being used in harsh environment, the MTMM-122-12-G-D-275 is also suitable for use in high voltage applications, as the contacts are designed to handle high voltage without compromising the electrical connection.
Finally, the MTMM-122-12-G-D-275 is also suitable for use in applications requiring a high level of security, as the crimped connection makes it very difficult to tamper with the contacts.
