MTSW-101-21-T-S-1239

Rectangular Connectors – Headers, Male Pins

MTSW-101-21-T-S-1239 is an example of a rectangular header connector that uses male pins. This part number is part of the MTSW series from TE Connectivity. It is a single-row header with 16 pins, designed to mate with a combination of receptacles and female connectors. It is made of a thermoplastic material, Terminals and seals are tin-plated brass. The overall length is 22.1mm, width is 4.2mm, and the height is 4.5mm. The part is by shrouded type pin headers which means it has adhesive that prevents the wire from coming out.

Ideal Applications

The MTSW-101-21-T-S-1239 is a popular choice for applications in PCBs, computers, and telecommunication equipment due to its cost-effectiveness and flexibility. It is used as a connector for applications requiring signal transmission, such as PC motherboard expansion slots, power supply connectors, disk drives, and communications modules. Because of the multi- pin design, it is especially suitable for power connections.

Working Principle

The electrical contact at the mating face between the two components is maintained by a combination of pressure and physical interference. The male pins of the header connector are inserted into the receptacle or female connector. The retention force of the contact is maintained by surface tension, which is caused by the engagement of the pin casing, contact points and the receptacle cradle. As the pin is inserted, the contacts inside are compressed ensuring a strong and reliable connection. The physical interference creates an additional retention force due to friction, particularly in high vibration environments.

Conclusion

The MTSW-101-21-T-S-1239 is an ideal solution for power and signal connections when cost-effectiveness, reliable performance and flexibility are important. The male pins, combined with a strong retention force, ensure strong reliability in different electrical applications. The insulation materials used on the contact points protect contact surfaces from corrosion and ensures a reliable connection for the life of the product.
