ESW-122-48-G-S-LL Rectangular Connectors - Headers, Receptacles, Female Sockets: Application Field and Working Principle

ESW-122-48-G-S-LL rectangular connectors are part of a series of standard rectangular pc board headers and receptacles made of natural or black polyamide. This series of connectors provides electrical connections with established mating dimensions, compatible with headers and receptacles made in accordance with MIL-DTL-38999, Series I. The ESW-122-48-G-S-LL rectangular connectors feature an impressive 50A current rating and a ferrule capacity of 10A (bushed mount socket) or 12cfm (sleeve mount socket). Additionally, they are user-friendly and easy to install.

This type of connector is designed for use in lateral, side by side, or ganged panel mount applications. They are ideal for applications in the aerospace, military, and medical industries, as they are dependable and capable of meeting the stringent requirements demanded in these industries. As a result, they are commonly used in lighting fixtures, audio systems, motion control, seismic control, and instrumentation systems.

The ESW-122-48-G-S-LL rectangular connectors feature a bussed mount socket, which effectively simplifies the assembly process, as there is no need for individual ferrules to be mounted in the customer’s assembly. Furthermore, a sleeve-mount socket is available for customization and higher current carrying capacities. Another advantage of this type of connector is the availability of board locks or board guides that provide positive line stability under mechanical shock or vibration conditions.

In terms of its operation, the ESW-122-48-G-S-LL connector consists of a shell, a contact sleeve, a contact pin, a sealing plug, and a cover:

• The shell is the protective cover of the connector assembly. It is used to provide environmental protection for the contacts and frictional locks.
• The contact sleeve provides electrical continuity between the mating components.
• The contact pin is used to provide electrical continuity in the contact system.
• The sealing plug may be used to provide environmental sealing in certain applications.
• The cover is used to protect the contacts and the internal components of the connector assembly.

These components collectively work together to create a dependable and reliable electrical contact between mating parts. When an external force is applied to the connector, the contact pins and contact sleeves move together to provide an electrical connection that is mechanically secure and dependable. The shell also provides additional protection for the contact system and seals to keep any external contaminants from entering the internal components.

Additionally, the ESW-122-48-G-S-LL rectangular connectors feature black polyamide housings with an operating temperature range of - 40 °C to + 125 °C and humidity resistance up to 90%. This ensures that they are suitable for a wide variety of applications and environments. The connector is also rated to IEC 60512-99-016 for shock and vibration resistance.

All in all, the ESW-122-48-G-S-LL series of rectangular connectors from HARTING provide reliable and secure electrical connections between mating parts. They are designed to meet the integrated and complex needs of the aerospace, military, and medical industries while remaining user-friendly and easy to install.
