Rectangular connectors — headers, male pins — are primarily used to connect two pieces of electronic equipment, often a cable or piece of hardware, to a motherboard or other printed circuit board. The type of connector to be used depends on the application, and one of the most commonly used is the MMT-134-02-L-DH-TR. In this article we\'ll discuss the application field and working principle of this connector.

MMT-134-02-L-DH-TR connectors are most commonly used in telecommunications, industrial automation, consumer electronics, and computer networking applications. They are a widely used, keying-based system, which allows for easier mating and unmating than traditional screw-type systems. Additionally, the MMT-134-02-L-DH-TR design allows for precise alignment of the pins to ensure that all connections are properly made.

The MMT-134-02-L-DH-TR connector utilizes two rows of four pins each on a dual-row header. The pins are arranged such that the leads extend directly from the bottom of the connector body. The contacts are 0.072" in diameter, and have a centerline spacing of 0.200". The retained metal shell securely holds the contact pins in place, and the mating face has a wall thickness of 0.019".

The working principle of the MMT-134-02-L-DH-TR connector is based on the contact between the male and female connectors. The MMT-134-02-L-DH-TR utilizes a physical barrier of plastic, which prevents the metal contacts on the male connector from having direct physical contact with those on the female connector. This prevents accidental contact and ensures that all connections are made properly.

Once the male and female components of the MMT-134-02-L-DH-TR are mated, the contacts are automatically polarized to ensure that a connection is made in the correct direction. This provides a superior ground and power connection as well as improving signal integrity. Additionally, the contacts are shrouded to provide dust and moisture protection.

In summary, the MMT-134-02-L-DH-TR connector is a widely used system, particularly for telecommunications, consumer electronics, and computer networking applications. It utilizes a physical barrier to prevent accidental contact between the metal contacts, and also automatically polarizes the contacts to ensure proper connection. Additionally, the contacts are shrouded for improved dust and moisture protection.
