TMM-102-01-S-S Application Field & Working Principle - Rectangular Connectors - Headers, Male Pins

Introduction

The TMM-102-01-S-S from JST is a low-profile, high-density, non-zippered, quality 10/100 Base-T connector that is specifically designed for reliable Ethernet connections. This connector is equipped with two rows of two pins each, providing a total of four contacts. The TMM-102-01-S-S is also fully compliant with 10/100 Base-T specifications.

Application Field

The TMM-102-01-S-S is a highly reliable connector for Ethernet applications, and it is commonly seen in numerous applications, such as industrial control, automotive, consumer electronics, medical equipment, instrumentation, communications, and test applications. This connector is ideal for Ethernet connections in these applications.

Design Details

The TMM-102-01-S-S features two rows of two pins each, providing a total of four conductive contacts arranged in a rectangular configuration. It has a robust shell design composed of a glass-filled polycarbonate material and a zinc-plated steel cable clamp. The electrical grounding is provided by the shells and a solid electrogalvanized finish is available to enhance robustness. A robust flat bezel is provided for positive latching and secure connection. Additionally, the TMM-102-01-S-S is equipped with a backshell occupying the full space behind the connector, ensuring a robust and reliable connection.

Working Principle

The two parts of the TMM-102-01-S-S consist of a housing and a female contact portion. The female contact portion contains the four contacts, arranged in two rectangular rows. The contact retention is ensured by a positive latching action after the female connector has been snap-fit into the housing. Once connected, the female contact portion is held securely inside the housing by a series of latches.

The TMM-102-01-S-S’s connection is via four 5A rated, dual-beam female contacts. The female contacts operate by interlacing and forming an electrical connection when the female portion has been snapped-in. The latch-action ensures that the female contacts will remain in contact with the male pins of the connected device. The contact forces of the four contacts self-align, creating a reliable connection. Additionally, the EMI-resistant constructions make the connection highly resistant to electromagnetic interference, ensuring a quality connection.

Conclusion

The TMM-102-01-S-S is a high-density and low-profile connector that can be utilized for Ethernet connection. It is equipped with two rows of two male pins, offering four electrical contacts, and is widely used in numerous applications, such as industrial control, automotive, consumer electronics, medical equipment, instrumentation, communications, and test applications. Its robust shell design and positive latching ensure a quality and secure connection, while its EMI-resistant design make it resistant to interference. The female contacts are self-aligning and form an Electrical connection with the male pins when the female portion is snapped-in, ensuring a reliable connection.
