The MTMM-103-04-G-S-157 are rectangular connectors, headers, and male pins which is positioned and engineered for reliable connections when used conjoined with mate connectors and frames.

Connectors Overview

The MTMM-103-04-G-S-157 is a family of epoxy filled, glass-filled polyester enclosed, and printed boards which facilitate fast single connection. The parts are tin plated coated and made of high quality phosphor bronze material with gold plated sockets. It has been tested to be compliant with UL and CSA certifications.

The rectangular connectors belong to the category of vertical pin header and vertical socket. They comprise of a solder cup with a tip and a body; also, the pitch is 2.54mm. The inner contact surface of the connector offers a friction fit with a mate connector. The header fits securely and resists any changes due to vibration and other external hardships which results in a reliable connection system.

Pin Header Specifications

The pin header come in a 2.54mm pitch with 4 pins and the positive locking feature. It is made of phosphor bronze material with gold plated sockets to increase conductivity. Furthermore, its resistance to corrosion enables it to outlast and remain connected over long periods. Additionally, when combined with its mate connectors it stays secured for better and reliable connections keeping the data secure.

The pins included in the pin header come in four types including straight, left angle, right angle, and down pitch. The pitch in the pin header is 2.54mm and the 0.45μm gold plated sockets are designed to be removable and replaceable.

Socket Specifications

The sockets are composed of 1.27mm pin/socket for reliable mates and they have 1mm pitch. The sockets are gold plated for a strong connection to the pins and are the most reliable in terms of stability and durability. The gold plating enables the connector to keep the connection secure even when used in harsher conditions.

The circuit protection is further enhanced due to the epoxy coating which is applied to the pin header contact area. Furthermore, the number of contact points allowed will depend on the number of lever arms inserted into the socket, with the four-armed pins being the most common.

Application Field and Working Principle

The applications field quite extensive and can be used in a variety of products and devises. It is excellent for temporary connectors, miniaturised connectors and many types of device interconnection. These connectors are highly-compatible with many electrical components and always provide reliable and robust connections. Examples of such include industrial and domestic products such as PCs, laptops, smartphones and tablets.

The MTMM-103-04-G-S-157 is designed to be used in dynamic use cases, thus they need to operate precisely even under conditions of vibration, shock, and temperature extremes. To enable this, the friction fit is provided by the pins along with their gold plated sockets. The contacts in the header are designed in a manner that enables a positive lock which restricts any undesired connections.

Hence, when the sockets and headers are combined, the pins provide a reliable friction fit between them which keeps the connection stable and shock resistant. Furthermore, due to the gold plating in the socket, it ensures corrosion protection and helps the pin to remain reliable for long periods.
