The MTMM-103-04-G-D-020 is a product of rectangular connectors – headers, male pins. It is a Class III, UL1950 approved device that provides a means of assuring the required insulation between different parts of a mating printed circuit board. This connector is used for dependable and effective interconnection of signal, power and ground paths between two printed circuit boards.

Dimensions

MTMM-103-04-G-D-020 has a standard double row, 4-position shrouded header series with an insulation gap of 1.0mm between mating surfaces. The overall dimensions of this connector are 8.6 x 4.6 x 4.0mm and the pins have a diameter of 0.64mm. It has a material finish of gold plated over copper with stainless steel clips.

Application Field

The MTMM-103-04-G-D-020 is ideal for medical and industrial applications that require electrical insulation between two connected boards. This connector is widely used in hand-held medical equipment, such as pulse oximeters, glucose meters, and syringe pumps; along with many other applications such as digital TVs, telecommunication devices and robotics.

Working Principle

The MTMM-103-04-G-D-020 works by using force from a pair of stainless steel clips – which are attached to the connector – to draw the two parts of the connector together. This creates an electrical connection between the two PCBs. The male pin is inserted into the female socket and the stainless steel clips are pressed onto the female socket. This creates the required electrical contact that passes the signal, power and ground between the two printed circuit boards. Additionally, the electrical contact provides the required insulation between the two passing signals and this helps to minimize potential problems due to static charge.

Conclusion

The MTMM-103-04-G-D-020 is a 4-position shrouded header series of rectangular connectors – headers, male pins, that provides a reliable contact for the safe transfer of signal, power and ground between two printed circuit boards. This connector is ideal for medical and industrial applications that require electrical insulation between two connected boards. In addition to its Class III, UL1950 certification, this product has a finish of gold plated over copper with stainless steel clips which helps to maintain a perfect connection. Moreover, it is very easy to use and can be quickly installed to connect two printed circuit boards.
