MTSW-140-22-G-D-394 is a type of rectangular connector which belongs to the category of headers, male pins. It is widely used for electronic transmission and connection for both PCBs and applicable wires, compatible with the density of 0,635mm. As for the working principle and other details, this essay will walk you through it.

MTSW-140-22-G-D-394 Overview

This type of rectangular connector utilizes a single row construction, which consists of 140 pins in total. Each pin is distanced apart 0,635mm from the next one in order to allow a seamless connection. Furthermore, the male pins arranged 6x2.32mm, delivering peak current rating of 2A. The total length of each pin comprises 2,54mm, as recommended in the industry for higher contact reliability, and each pin is preloaded to achieve a better fit between the two objects to transfer current.

Common Applications

MTSW-140-22-G-D-394 connectors are mostly used in the electronics industry for PCBs, wire, sheet steel or cable connection. Thanks to the distance regulation between each pin, it can effectively transfer signals or either component’s data from one side to another, making it suitable for applications such as electric fans, lighting systems and motor controls.

Working Principle

The MTSW-140-22-G-D-394 connector features a single row construction, with 120 male pins connected to one another with distance regulation of 0,635mm. This allows the connection of both PCBs and applicable wires. The material of the connector is tin-plated copper, excellent for transferring current and providing a reliable connection. Furthermore, the pins are preloaded as to achieve a better fit that will last during the transfer of current.

The connector utilizes spades as the common connection way: the device’s side has a hole with a circular section with a diameter of 3mm, and a minimum section of 8mm, perfect for soldering, while the other end of the connector has an external terminal suitable for solderless connections or pins that can be connected to the PCB. This also allows a better connection between PCBs and applicable wires, enabling the current to flow without any problems.

Advantages

The spacing enabled by the MTSW-140-22-G-D-394 connector makes it perfect for making multi-signal transfers between PCBs and applicable wires. Furthermore, its pre-loaded properties makes for an extremely reliable connection between the two sides, allowing for increased control and better current transfer. On top of that, the pins are constructed of tin-plated copper, which is much better than steel or nickel-plated copper when it comes to electricity and connection.

Disadvantages

The MTSW-140-22-G-D-394 has few to no disadvantages. The contact area between the male pin and the female end is flimsy and can be easily damaged. To prevent this problem, users need to take extra steps in ensuring the safety and security of the connection. Furthermore, due to the connector’s single row construction and high pin count, the material is prone to overheating. For this, users should install a heat sink to successfully dissipate the heat.

Conclusion

The MTSW-140-22-G-D-394 is an incredibly useful connector thanks to its single row construction and two different ways of connecting PCBs and applicable wires (either soldering or solderless connection). The tin-plated copper construction makes it highly conductive and reliable for signal transferring. Although it may be prone to overheating, users can mitigate the problem by using a heat sink. Overall, the MTSW-140-22-G-D-394 is an excellent way to connect two different points in a given circuit.
