Rectangular Connectors - Headers, Receptacles, Female Sockets

ESQ-123-49-G-T is a user-friendly rectangular connector that delivers reliable signal and power connections for a variety of applications. It is an 8-Position connector equipped with two polarizing features to ensure correct mating. This connector is compliant to military specifications and meets the requirements of military MOPAS (Micro Electronic Package and Assembly Specification).

The ESQ-123-49-G-T connector is designed for applications requiring a plug-in connection between a printed circuit board (PCB) and other mating members. It is routinely applied in handheld electronic products, medical devices, land and marine navigation systems, and high-reliability industrial electronics. The relatively small size of the ESQ-123-49-G-T especially makes it advantageous for confined spaces, allowing for mounting at various angles.

Application Field

The directional signal or power connection provided by the ESQ-123-49-G-T connector can be applied in multiple fields. It is a convenient solution for consumer electronics, including handheld mobile phones and digital cameras, as well as portable device such as PDAs and tablet computers. This connector is also used in the automotive and military industries, as well as medical and laboratory facilities that need advanced protection from EMI/RFI radiation.

Working Principle

The ESQ-123-49-G-T rectangular connector features two polarization features: one end features an 8-position flange, while the other end has an 8-position window. This set-up prevents any incorrect connection. Together with the flatness of the contact’s mating surface, the ESQ-123-49-G-T ensures the maximum strength of the connection, while it prevents accidental disconnection. It is also designed to resist extreme environmental conditions, due to its heat-resistant and corrosion-proof silicone construction.

The ESQ-123-49-G-T connector gets power through socket contacts that can safely transmit current up to 10-15 amps. Contact pins are soldered onto the PCB, and the plug gets inserted at the other end and then locked into place, providing a secure connection. The male end’s contacts ensure the correct orientation of the two halves, while the female end’s contacts ensure the reliable connection between the pin contacts and the plug.

English units of the ESQ-123-49-G-T connector come in a miniature-sized 8-position form factor that fits all kind of rack and panel applications and is designed for straight or 180° mated connections. The European units are slightly larger in size and feature insulation displacement contact (IDC) type sockets. Both forms provide reliable and durable connections in mission-critical applications, even with vibration and jolting.

The ESQ-123-49-G-T, with its fast and easy installation, high performance, and secure connection, makes a perfect choice for a variety of applications. Its polarizing design ensures that the correct orientation of the two mating parts is achieved, making sure that the connection is established properly.
