Introduction to Rectangular Connectors

Rectangular connectors are components that allow electrical signals, power, and data to be routed between two points. Also known as headers, these connectors typically pass through a PCB (Printed Circuit Board) and connect to other components, such as power supplies, variable resistors, capacitors, or other electrical equipment. They may also be used to connect devices externally, such as between larger boxes or housings. Rectangular connectors come in a variety of sizes, shapes and configurations, and RSM-125-02-L-D-K is a prime example.

RSM-125-02-L-D-K Connectors

RSM-125-02-L-D-K connectors are a type of rectangular connector that features a 2mm pitch and a 2.54mm row spacing. The connectors offer both header and receptacle solder connections, with the header having one row of 125 pins and the receptacle having two rows of 125 pins. In addition, they are equipped with through-hole mounting facilities for easy installation. They also have a low profile design, making them ideal for areas of tight space.

Applications and Working Principles of RSM-125-02-L-D-K Connectors

RSM-125-02-L-D-K connectors have a wide range of applications. They are commonly used in PCBs to provide reliable connection between two components, such as connecting a microcontroller to a power supply, connecting a microcontroller to a display, or connecting a motor driver to a DC motor. They are also widely used in industries such as automotive, robotics and industrial automation where reliable performance is a must.The working principle of the RSM-125-02-L-D-K connectors is simple and straightforward. The pins on the headers are inserted into corresponding holes on the circuit board, and the contacts on the receptacles are placed over the contact pads on the board. When mating, the contacts are aligned with their respective copper contacts on the board and the components are secured in place by screws. This ensures a reliable electrical connection and optimal performance in a variety of conditions.These connectors also feature a number of other features that contribute to their performance. For instance, their contacts are gold-plated, which ensures a low contact resistance and a reliable electrical connection. This makes them suitable for high-speed applications, such as data buses between controllers and motors. Additionally, their surface mount design makes them suitable for high-density applications.

Conclusion

RSM-125-02-L-D-K connectors are versatile, reliable, and highly durable rectangular connectors. With their low profile design, they are ideal for tight spaces, and the gold-plated contacts ensure a low contact resistance and a reliable electrical connection. Additionally, their through-hole mounting facility provides simple and secure installation, making them well suited for a variety of applications.
