A TMM-117-01-G-D is a rectangular connector header (male pin). It is designed to provide an easy connection between electronic products and equipment. The TMM-117-01-G-D usually refers to a 2.54 mm male connector with a 1 mm spacing. This type of connector is particularly useful for connection between small electronic components that need to transmit power and signals, such as soldering boards and surface mount devices.

Application Field

The TMM-117-01-G-D is widely used in the electronic industry, especially in electronic communication and digital equipment. Examples of applications include motherboards, digital circuit boards, and other electronic products. Apart from being used in automotive industries and household appliances, it is also used in medical devices, consumer electronics, energy, and aerospace field.

A TMM-117-01-G-D is ideal for applications that involve the transfer of digital signals and power between different components. Compared to the classic through-hole type connectors, TMM-117-01-G-D is more cost effective and much easier to solder and assemble. Additionally, its small size makes it the best choice for applications that require a compact design.

Working Principle

TMM-117-01-G-D is a single-row, 2.54mm pitch, and 4-pin connector with a current-carrying capacity of up to 1.5A. It consists of an insulator, contacts, and a mating retention member. The contact pin is insulation-displacement type, and has gold-plated termination which ensures reliable electrical and contact performance.

When an external connector is inserted into the TMM-117-01-G-D, the contact pin will penetrate the insulation layer of the external connector, thus creating a connection between the contact pin and the conductor inside. This mechanism enables these rectangular connectors to make a solid connection even when the external connector is not completely inserted.

The TMM-117-01-G-D is designed to have excellent electromagnetic compatibility (EMC) performance. The internal contact pin is insulated from each other with plastic dividers which prevent crosstalk, thereby ensuring interference-free signal transmission. It is also designed to be corrosion-resistant and heat-resistant, allowing reliable and durable connections.
