ESW-125-39-G-S-LL

Rectangular Connectors - Headers, Receptacles, Female Sockets

The ESW-125-39-G-S-LL is a popular rectangular connector. It consists of a male and a female part, connected by two parallel rows of pins. The pins are held in place by an insert flap on the female part and a practical “snap-system” on the male part. This type of rectangular connector is typically used in electronic assemblies for the medium power (up to 25 A) and high-frequency (up to 4 GHz) applications.

Application Field

These rectangular connectors can be used in a wide variety of applications. The most common application is as an electrical interconnect in power, signal, or control circuits. They are designed to be used for internal and external connections to a multitude of electrical devices, such as computers, monitors, batteries, power supplies, and other specialized equipment. They are also used in motor controllers, audio/video equipment, telecommunication devices, and automobile electronic systems.

The ESW-125-39-G-S-LL connector offers superior electrical and mechanical performance, with reliable contact force, excellent shielding, and high current carrying capabilities, making it suitable for use in a variety of applications from high-speed communications to automotive control applications. It is also designed for mating with other rectangular connectors, compliant components, and other connectors from the same ESW series.

Working Principle

The working principle of the ESW-125-39-G-S-LL rectangular connectors is based on the two sets of pins in each connector. The pins on each connector are arranged in two rows of 19 pins and each set of pins is connected together. The two groups of pins form a circuit and a connection is established when the two connectors are mated and the pins make contact. The pins are held in place with a practical snap-system on the male end and an insert flap on the female part.

The connector has an impedance of 50 Ohms and is designed to carry up to 25 A of current, making it suitable for power applications. The design also offers excellent shielding of the signal and power lines against crosstalk and electromagnetic interference (EMI) as well as a reliable contact force to ensure a reliable connection. In addition, the pins are plated to enhance corrosion resistance and durability.

The ESW-125-39-G-S-LL is a robust and reliable rectangular connector. It is durable and has a low insertion force for easy use. Its design makes it ideal for a wide variety of applications, from computers to telecommunication devices and motor controllers.
