Rectangular connectors are one of the most common types of connectors used in the electronic industry today. They are commonly used to connect various devices including sensors, ports, and switches. A TSW-140-26-L-D is a type of rectangular connector, under the classification of headers, male pins. An understanding of its application fields and working principles is essential for proper use and maintenance of the device.

Application Field

The advantage of using this type of connector is that it is compact, yet provides sturdy connection and reliable contact. The TSW-140-26-L-D is designed for PCB connections and is most suitable for signal transmission and power distribution applications. It is commonly used in circuit boards due to its low profile design, ease of assembly, and stable contact resistance.

The metal housing allows for strain relief and improved mechanical robustness, and the integral male pins provide reliable co-planarity when mating. In addition, the gold plating on the contacts provides optimal protection against humidity and corrosion, which makes it suitable for harsh environments and extended exposure to extreme temperatures. The design of this header makes it suitable for general purpose applications such as industrial, automotive, and medical.

Working Principle

The working principle of this connector is simple and straightforward. To begin, the contacts are assembled into the channel of plastic sleeve. The sleeve acts as a guide for the contact and an insulator between components. The contacts are then securely held in place by a pair of metal clips, which are used to secure them tightly against the PCB. Then, when the pins are wiped across the board, they make contact with the copper pads, thus establishing a connection between the two components.

Once the connection is made, current passes through the contacts, which then transfer the electrical signal to the other device. As the current is transferred, the contacts in the header become hot and the metal clips secure the contacts in place so they stay firmly connected. The clips also protect against vibration and flexing, which ensures a secure connection even over time.

Conclusion

The TSW-140-26-L-D is a type of rectangular connector, under the classification of headers, male pins. It is commonly used for established PCB connections and provides reliable signal transmission. It features a metal housing for strain relief and excellent contact resistance, and its small profile allows it to be used in confined spaces. In addition, its gold plating on the contacts provides protection against corrosion and enhances durability. The connector is ideal for general purpose applications such as industrial, automotive, and medical.
