Rectangular connectors, also known as headers, receptacles, and female sockets, include a vast variety of products featuring different dimensions, pin counts, mechanical and electrical characteristics. The ESW-121-59-S-S-LL model belongs to this category and it’s used in a variety of applications. The following section will provide an overview of the properties of ESW-121-59-S-S-LL and explain its working principle.

ESW-121-59-S-S-LL Properties

The ESW-121-59-S-S-LL is an 8-position, 2-row, vertical header connector, featuring a design that accommodates up to 8-pins for creating electrical connections between two discrete surfaces. It has a rated current of 15A, a rated voltage of 300V AC, a wire gauge of 24-26AWG, and a contact resistance of less than 10 milli-ohms. Its insulators are made of high-temperature thermoplastic UL94V-0, whereas the contact and inlay parts are constructed of copper alloys.

Moreover, the ESW-121-59-S-S-LL features a standard above-board mounting process, which means it may be installed on PCBs without soldering and be removed by pressing down the locking tab. The connector also has a dual lock design that ensures a secure fit and a durable performance. The dual lock has two sections, the lock lock tab and the exit lock tab. When both the lock and exit tabs are pressed down, it ensures that the connector is firmly fastened in such a way to withstand dynamic forces.

ESW-121-59-S-S-LL Working Principle

The ESW-121-59-S-S-LL rectangular connector works through an electrical current path. Electrical current is created by the installation of pins that line up with holes in the PCB, which act as conductors. The copper alloys used in contact and inlay parts are designed to have a low contact resistance so as to reduce heat dissipation. On the contrary, the thermoplastic insulation prevents the passage of any electrical current between the pins.

The two rows of metal contact pins provide a connection between the two surfaces. Each pin is designed to accept up to 24-26 AWG gauge wire,insulating it from the other pins. Additionally, the exit lock tab offers a secure fit with a good electrical interface between the device and the PCB. Finally, the through-hole style mounting enables the connector to be tapped into the PCB and firmly connected to it.

ESW-121-59-S-S-LL Application Fields

ESW-121-59-S-S-LL connectors are ideal for a variety of applications, from interconnecting discrete components to power electronics to computer-based control systems. They are suitable for electrical contact and signal connections in the telecommunications, automotive, and industrial manufacturing industries, among others. In addition, they are designed to meet IP67/IP68 ingress protection ratings, making them suitable for harsh environment or dust-proof applications.

They are also commonly used for connecting two different points in circuits, providing isolation between components, in order to maintain signal and power integrity. For example, it can be used for the connection of battery packs, LED lighting strips, power supplies, ground lines, or input and output signals.

Conclusion

In conclusion, the ESW-121-59-S-S-LL rectangular connector is an 8-way, 2-row vertical connector that serves a variety of applications. Its insulators are made of thermoplastic and its contact and inlay parts are constructed of copper alloys for low contact resistance. It has a rated current of 15A, a rated voltage of 300V AC, a wire gauge of 24-26AWG, and a contact resistance of 10 milli-ohms. It is ideal for connecting discrete components, power electronics, and control boards, and is often used in the telecommunications, automotive, and industrial manufacturing industries.
