Rectangular Connectors - Headers, Receptacles, Female Sockets play a significant role in allowing the transmission of signals and power between electronic components. ESQ-128-37-G-S-LL is a particular type of receptacle connector that consists of 128 contacts in a double-row horizontal format. The unique features of this connector include its very low profile height of only 2.75mm and its maximum operating temperature of up to +125°C, allowing the connector to be used in more demanding applications and extreme environments. Below, we will discuss the application fields and working principle of the ESQ-128-37-G-S-LL.

Application Fields

The ESQ-128-37-G-S-LL is well-suited to any application that requires a low-profile connector, as well as extreme temperature resistance. It is especially suited to applications that require high performance in the transportation, industrial, automation, medical, and consumer electronic markets. This makes it an ideal choice for applications such as safety electronics, HMI (Human Machine Interface) displays, and joystick control systems.

The double-row horizontal arrangement of the connector ensures that it can be used in tight spaces with ease. Since it is made with a high-density housing, the connector is suitable for applications with limited space and high signal density. Furthermore, due to its very low profile height of only 2.75mm, the connector can often be used even in those applications that demand a more compact profile. This ensures that the connector can also be used in applications where precise dimensional requirements are present.

Working Principle

The ESQ-128-37-G-S-LL consists of 128 individual female contacts that are arranged in a double-row, horizontal format. Each contact has a plated-through hole in its center, which allows for the insertion of a male pin, allowing them to transmit power or signals between electronic components. The connector also has two polarizing tabs, which help ensure that the connector is properly aligned and can only be inserted one way. This assures that the correct connection is being made, and helps to prevent potential damage to the pins due to incorrect alignment.

The connector’s contacts are made out of high-quality brass and have a gold plating of up to 7µm. This ensures a secure connection and ensures that the connector can handle a high number of insertions and removals over its lifetime. This also improves the connectors’ high temperature capability, while its high frequency performance is enhanced by a special double-contact design, which reduces crosstalk. Furthermore, the unique top insertion feature helps lower the time it takes to assemble the connector, making it a better choice for automated processes.

Conclusion

The ESQ-128-37-G-S-LL is an ideal choice for applications that demand a low-profile connector, high signal density, and extreme temperature resistance. Its high-quality brass contacts and gold plating allows the connector to handle a high number of insertions and removals over its lifetime, while its double-contact design helps to reduce crosstalk. Furthermore, the top insertion feature makes it ideal for automated processes. As such, the connector is well-suited to a variety of applications in the transportation, industrial, automation, medical, and consumer electronic markets.
